VRQF is the RMS deviation in the fundamental component of an AC voltage from a desired AC voltage. It is computed as the square root of the sum of the squares of deviations in the fundamental component of the voltage from the desired value. The sum is computed as a running recursive average of frequently taken samples of the fundamental component, obtained in at least one full cycle of the wave. The time constant of the recursive computation is 6 hours. The recursive average takes at least six hours to settle to a proper sum, and is generally never stopped, once started.

Introduction – 1

1 Introduction

The Beckwith M-2601/02/03 Series of Autodaptive Regulator Controls (ARC) are unique microcontroller-based solutions to regulator control requirements. Using conventional inputs, the control accomplishes regulator control, based on voltage. The unit has a user-defined Bandcenter and Voltage Regulation Quality Factor (VRQF) that permits optimization of the tapchanging process, as well as a variety of configuration setpoints to allow maximum flexibility.

The ARC senses voltage and current which permits the control of voltage through the regulator. The control utilizes nonlinear integrating algorithms which adapt to system operating conditions to reduce the number of tapchanger operations while maintaining the desired VRQF.

The ARC is protected from noise and transients likely to be found in typical regulator control applications. The control is designed to withstand the application of 1500 V ac for one minute between any terminal and ground connection, and meets or surpasses the requirements of ANSI/IEEE C.37.90.1-1989, which define surge withstand capability.

Interrogation of the control and setting changes are made through an optically-isolated RS-232 communications port mounted on the front of the unit. Using the M-2802 SLIMcom™ software, with a computer running Microsoft® Windows 95/98, the user can configure and monitor operation of the unit. Two passwords are available to the user and are accessed through the communications port. All setpoints are stored in nonvolatile memory which is unaffected by control voltage disturbances.

Two operation counters are provided. One counter may be reset; the other may be preset. The control has adjustable bandcenter, over and undervoltage, runback, and line drop compensation.

Nine LEDs are used to indicate Regulator RAISE and LOWER (Fast, Intermediate and Slow) command status, CPU OK, REV PWR, and NEUTRAL LIGHT.

The basic control settings allow regulation of the voltage at a remote location while assuring that the customer nearest the regulator is protected against overvoltage.

The control has a VT User Correction Voltage setting, and the capability to correct for current transformer and voltage transformer phasing connections without making wiring changes. This feature allows phase angle corrections in 30° increments from 0° to 330°.

M-2601/02/03 Instruction Book

The Autodaptive® Regulator Control uses a Motorola microcontroller which has a self-testing watchdog system, which is illustrated in Figure 1-1, below.

Use of LDC

The use of Line Drop Compensation (LDC) is outlined in Section 4.2, Voltage Regulation. This feature is recommended for use on regulators connected to distribution feeders which have switched capacitor banks that are controlled by Beckwith M-2501 Series Autodaptive Capacitor Controls, placed beyond the theoretical load center, or where other methods of cap bank control are used.

2.1 COMM Port ............................................................................... 2–1

2.2 Status Indicators ....................................................................... 2–1

2.0 Introduction

The front-panel user interface consists of an RS-232 serial communications port and five status indicators as shown in Figure 2-1, M-2601 Front Panel (M-2602 and M-2603 each possess identical user interface).

2.1 COMM Port

The RS-232 serial communications port is located at the top of the Autodaptive® Regulator Control front panel. Connections are made through a standard DE-9 type female connector. The pinout is of the computer type (DTE) configuration, and will typically require a null-modem type cable. See Appendix A, Null Modem Cable for pinout.

2.2 Status Indicators

RAISE LEDs – These LEDs indicate that the voltage

is below the band and the timer has started timing for a tapchanger raise operation. The timer circuit first illuminates a GREEN LED, to indicate the initial timing phase, which is greater than 5 minutes to the anticipated switch operation. The middle timing period is indicated by an AMBER LED, which anticipates a switch operation in one to five minutes, and the final timing phase prior to switching is indicated by illuminating a RED LED, which anticipates a switch operation in less than 1 minute.

2–1

Page 25

M-2601/02/03 Instruction Book

LOWER LEDs – These LEDs indicate that the

voltage is above the band and the timer has started timing for a tapchanger lower operation. The timer circuit first illuminates a GREEN LED, to indicate the initial timing phase, which is greater than 5 minutes to the anticipated switch operation. The middle timing period is indicated by an AMBER LED, which anticipates a switch operation in one to five minutes, and the final timing phase prior to switching is indicated by illuminating a RED LED, which anticipates a switch operation in less than 1 minute.

CPU OK LED – The GREEN LED will flash at approximately 1 Hz whenever power is applied to the unit and the watchdog program (internal to the microcontroller), indicates the microcontroller is working properly.

Each time the control is powered up, it will briefly light all LED's to verify that LED indicators are functioning properly. After that brief period, the CPU

OK LED will begin flashing.

REV PWR LED – The RED LED will light to indicate

when the unit detects reverse power flow.

NEUTRAL LIGHT LED – This AMBER LED will light when the regulator is in the neutral tap position.

3.4 Transient Protection

In the Autodaptive® Regulator Control, transient voltages are suppressed by varistors.

Multiple VT grounds far apart must be avoided, however, since a varying difference in ground potential could add or subtract from the effective potential and cause a variation in the voltage setpoint.

3.5 External Connections

External connections are accomplished via a (12connection) terminal strip located on the rear of the unit. See Figures 3-4, 3-8, and 3-12, External Connections, for connection points.

Terminal 1 – Counter Input

This digital input registers the counter contact closure. The operation count will increment when terminal 1 is connected to neutral (terminal 7) or disconnected from neutral through an external dry contact. The counter is configured through SLIMcom for X1 level sensing (G.E. regulators) or X2-edge sensing (Siemens regulators) operation. See Chapter 7 for details.

Terminal 2 – Load Current Polarity

The line current input range is 0–400 mA with 200 mA representing the nominal 1.0 per unit value. The measured current value is used for line drop compensation and metering calculations.

Terminal 3 – Load Current Return

This is the non-polarity input to the load current measuring transformer. The companion polarity input is terminal 2. The line current transformer input is isolated from other terminals.

Terminal 4 – Neutral Position (Neutral)

This is the input to the Neutral side of the Neutral Contact detection circuit. It is connected to the Neutral Contact output of the Regulator.

Terminal 5 – Neutral Position (Hot)

This is the input to the Hot side of the Neutral Contact detection circuit. It is connected to 120 V ac via the harness.

Terminal 6 – Tapchanger Lower Output

This switched output connects the tapchanger lower winding or an interposing relay to the source of

motor power. It is capable of switching up to 6 A at 120/240 V ac.

Terminal 7 – Neutral

This is the return for the voltage input (terminal

9).

Terminal 8 – Tapchanger Raise Output

This switched output connects the tapchanger raise winding or an interposing relay to the source of motor power. It is capable of switching up to 6 A at 120/240 V ac.

Terminal 9 – Motor Hold

This output is used only with Cooper Regulators. It is left open for Siemens and GE Regulators.

Terminal 10 – Drag Hands Reset

This output is used to activate the Drag Hands Reset mechanism. It is protected by F4, a 2 A fuse.

Terminal 11 – Motor Power Input

The source for powering the tapchanger motor or interposing relay is connected here. It may have a nominal voltage of 120 or 240 V ac. This input is protected by F1, a 6 ampere fuse. Direct current may

not

be switched through these contacts.

Terminal 12 – Voltage Input

This input accepts nominal 120 V ac, 60 Hz to operate the control's power supply and voltage sensing input. The acceptable voltage range for proper control operation is from 80–140 V ac. Power consumption is 6 VA or less. The input voltage is referenced to line neutral (terminal 3). This input is protected by a 0.25 A fuse, F2. The unit will withstand 1000 V ac hi-pot from neutral to ground, since it is recommended that the VT neutral be grounded at only one point.

See Figure 3-4 for typical external connections.

■ NOTES:

■■

1. Motor voltage may be 120 or 240 V to neutral or 240 V phase-to-phase.

2. The customer is to provide earth ground connection to CT/VT's neutral connection, external to the control.

4.0 Introduction

The Autodaptive® Regulator Control (ARC) is a unique control that relies on Autodaptive-style algorithms to optimize voltage control while minimizing the number of tapchange operations required. This results in reduced tapchanger maintenance and optimized loading.

VRQF

VRQF (Voltage Regulation Quality Factor) is defined as the RMS deviation in voltage from a reference voltage, as averaged over a selected time period. The reference voltage for Autodaptive

Regulator Controls is the voltage setpoint of the control. One purpose for the regulator control is to minimize the VRQF or variation of the supply voltage on a distribution system.

Use of the VRQF algorithm rather than conventional voltage setpoint/bandwidth/preset timer results in more precise distribution voltages with reduced tap operations. The autodaptive voltage controls operate with a voltage setpoint and a desired VRQF setting. The bandwidth is a function of the tapchanger voltage change per tap, and the timing is adapted from past voltage (VRQF) history, and the desired VRQF at the bus.

4–1

Page 41

M-2601/02/03 Instruction Book

For example, with a condition of 5/8% taps (0.75 V) (therefore 1 V bandwidth setting), if the bus voltage varies more than 0.5 V (1/2 of bandwidth) from the voltage setting, the regulator control will begin timing towards an operation. The accumulating timer has an operational threshold which is adapted from the VRQF history and the VRQF setting. If the history illustrates a VRQF less than the setting (indicating a relatively stable bus voltage), the threshold will be increased. This allows the natural stability of the system to correct the voltage, and in many cases to avoid the need for a tapchange. If the history illustrates a VRQF higher than the setting (indicating a relatively variable bus voltage), the threshold will be decreased. This allows tapchanges to occur sooner, and system voltage variations to be minimized.

VAr Bias

Use of VAr Bias allows the Autodaptive® Regulator Control (ARC) to coordinate its operation with the M-2501A Autodaptive Capacitor Control (ACC) devices on the distribution system in order to minimize losses, subsequent voltage variations, and equipment capacity requirements of transmitting VArs.

The application of both the ARC and the ACCs on a circuit provides for an interaction between the devices that provides for faster response in times of rapidly changing conditions on the distribution system. This application combination adds a “substation requirements” aspect to the feeder requirements control of pole-top capacitor banks.

For example, with one transformer, six feeders, and 1200 KVAr pole-top feeder capacitor banks, if each feeder is correctly compensated to within 400 KVAr, all feeder bank controls would be operating correctly. However, the transformer would be transforming 2400 KVAr (six feeders times 400 KVAr) from the transmission system. The ARC on the transformer would detect this condition and affect additional line capacitor operation by making a temporary voltage level setting change. By effectively delaying a voltage tap change for a short time, a line capacitor bank control could be biased into operation by the tapchanger control, with reduced losses, better voltage profiles, and fewer tap changes.

4.1 Measurements & Calculations

Voltage Measurements

Normal

The ARC accomplishes waveform sampling by sampling a 60 Hz signal at a rate of four hundred and eighty samples per cycle, or two hundred and forty samples per half-cycle. This measurement is repeated twenty times per second. Two conditions terminate the sampling for one halfcycle. They are:

1. The voltage being sampled crosses the zero value line.

2. 240 voltage samples have been collected.

These samples are correlated with sine table entries and processed to produce a voltage value. This voltage is the fundamental component of the voltage wave.

Bandcenter

In the ARC, Bandcenter is the value of voltage selected by the customer as the desired value of voltage for regulation. This value is the center point for the selected bandwidth.

measured

is the value of voltage which the control

measures for regulation.

Current Measurements

Line Current

Current is measured by its two components with respect to the voltage signal, the in-phase or real component (P) and the 90° or quadrature component (Q). Values of P run from a positive maximum to a negative maximum. Values of Q run from a positive to a negative maximum, with the negative values indicating a lagging power factor on the load.

A vector sum of these current components is displayed as secondary current.

RAILS AND LIMITS Lower Voltage Limit

If the value of the regulated voltage is below the Lower Voltage Limit, the control will not time towards a lower tapchange.

Upper Voltage Limit

If the value of the regulated voltage exceeds the Over Voltage Limit, the control will not time towards a raise tapchange. If the value of the regulated voltage exceeds the overvoltage limit plus a 2 volt Deadband, the control will issue a lower command in one second until the regulated voltage falls, at minimum, back into the deadband.

Tap Position Limits

The control is programmable to prevent automatic tapchanges that will allow excursions beyond the set values of minimum and maximum tap positions. This function does not have priority over any values of Voltage Limits programmed into the control.

4.2 Voltage Regulation

Standard Control Settings

With the Level 1 password implemented, the following setpoints are adjustable: BandCenter, Line Drop Compensation, Upper Voltage Limit, Lower Voltage Limit, and VRQF. The History sample period is also adjustable. Alarm Enables and Resets are settable, and VAr management can be enabled or disabled. See Table 4-1 for the ranges. All other setpoints and configuration choices require level 2 password clearance.

The control will send commands to the tapchanger to change taps as needed to hold the voltage within the bandwidth setting, as modified by the line drop compensation settings.

The control will only respond to an out-of-band voltage excursion after the timer has reached the Autodaptive

time delay which is set by the algorithms. The algorithm functions as an integrating timer dependent on the VRQF, which increments during time out-of-band and decrements during time in band, but not below zero. The further the voltage is away from the setpoint, the shorter the time delay between tapchanges and vice versa.

Bandcenter

The center of the voltage band is adjustable from 90 to 135 V ac in 0.1 volt increments.

Voltage Regulation Without LDC

When the control is only used to regulate the voltage on the transformer or regulator low-side bus, the only input required is voltage from a lineto-line or line-to-ground VT with a nominal 120 V ac secondary.

Voltage Regulation with LDC

When it is desirable to regulate the voltage at some distance from the transformer or voltage regulator, the Line Drop Compensation (LDC) feature is used.

The bandcenter function is set the same as if LDC were not used, and still represents the desired voltage at the remote location.

Password Applicability

Metering panel and list can be read under all circumstances.

No Password: Setpoint screen can be read, but not changed. Config screen cannot be read.

Level 1 Password: Setpoint screen can be read, but only bandcenter, limits, alarms, LDC, VRQF and history sampling can be changed. Ratio Corr, multipliers, CT phasing, counters, and clock cannot be changed. Config screen cannot be read.

Level 2 Password: All parameters in Setpoint screen can be changed. Config screen can be read and changed.

A classical approach can be used to determine the settings for the LDC, however this assumes a load center point and is usually not applicable to the typical distribution feeder. For more information, contact Beckwith Electric for Application Note #17.

A simpler method is recommended which will work for most applications. This involves analyzing the feeders leaving the station and estimating the reactance/resistance (X/R) ratio. The reactive and resistive line drop compensation setpoints should then be entered in this same X/R ratio.

If the CT and VT phasing corrections have been made, only positive values of R and X compensation need to be used.

Table 4-2, Approximate Ratio of Line Reactance to Resistance (X/R) of Typical Distribution Circuits, gives the X/R ratio for various wire sizes.

By knowing the ratio of the maximum expected load to the present load, the amount of voltage compensation needed is found as shown in the following example.

Example:

Desired: local voltage @ min load=120 volts

local voltage @ max load=124 volts

Using the following assumptions:

Desired Bandcenter = 120 volts Desired Bandwidth = 1 volt The device being controlled is 50%

loaded

Setting

Start with R=0 and X=0, and increase both values using the ratio shown in the table for the feeder conductor. Keeping the X/R ratio, increase R and X

until tapchanger raises the voltage by

set

two volts (50% of the desired voltage rise at full load).

With this simplified method of LDC setting, the first customer’s voltage will be limited by the upper voltage limit at the highest daily load, depending on the accuracy of the daily load projection. At the same time, the furthest customer will receive the highest voltage possible under the line and loading conditions. The first customer protection can be set on the control. Refer to Section 4.3, Regulation Limits.

Since the daily load projections will likely have a seasonal variation, the best balance of first customer to furthest customer voltage may require seasonal adjustment of the LDC settings. Note that the settings of R and X compensation are proportional to the peak load projection and that new settings can be scaled from the first setting obtained by the experimental process just described.

4.3 Regulation Limits

Upper Voltage Limit

A setpoint is available to establish a block raise limit. The overvoltage limit is adjustable from 90.0 V to 136.0 V. This limit is equivalent to a First Customer Protector to limit overvoltage from line drop compensation action during heavy loading.

If the voltage exceeds the upper voltage limit plus the 2 V deadband, the control will immediately call for an “automatic” lower without any time delay.

The upper voltage limit block can be effectively disabled by setting it to 136 V.

Lower Voltage Limit

This limit is adjustable from 89.0 V to 135.0 V in

1.0 V increments. This limit can be set to limit low customer voltage to safe limits and will block voltage reduction action that could cause motor stalling and other undesirable low voltage effects. Lower Voltage Limit can be effectively disabled by setting it to 89 volts. If the voltage is below the Lower Voltage Limit setpoint, the control will not issue further lower commands.

Tap Position Limits

This provides for the settings of upper and lower tap positions beyond which the control is blocked. Note that these settings can interact with the over and under voltage limits. Refer to Section 4.8, Tap Position.

The tap change output is initiated after the Autodaptive

integrating timer has timed out. The waiting time between the tap changes is adaptive, subject to a minimum value as set by the Intertap Minimum Delay.

4.5 Counters

Operations Counter

Two counters, resettable and presettable, are available on the Autodaptive Regulator Control. Both counters accommodate numbers up to 999,999, and will record from either an X1 or X2 operations counter output, settable in SLIMcom™.

The resettable counter is reset to zero by command, and does not retain the value prior to reset.

The presettable counter can be preset from zero to 999,999 by command, and does

not

retain the preset value after operations counts are received. Counters are not affected by a loss of power to the control.

4.6 CT/VT Phase Shift

With the CT and VT signals in-phase for unity power flow to the load, the control will properly calculate line drop compensation. In the majority of regulator operations, the CT and VT are inphase. If an application arises where the CT and VT are not in phase, the phase shift can be corrected through software. The characteristics of three phase systems only allow multiples of 30° phase shifts. The control, therefore, has a range of 0° to 330° in 30° increments.

When two single-phase regulators are connected in open delta, the current signals will be out-ofphase with the voltage signals. For one regulator, the current will lead the voltage by 30° and is called the “leading” regulator. For the “lagging” regulator, the current will lag the voltage by 30°.

4.4 Non-Sequential/Blocking

The control operates in non-sequential mode. The control will make one tapchange and then timeout once more before making another. This is accomplished by energizing an Output until a counter contact input is received.

4.7 Ratio Multipliers

VT User Correction Voltage This feature is included to permit VOLTAGE

TRANSFORMER ratio correction. It permits the

measured voltage to be adjusted over a K12 V ac range to compensate for voltage transformer ratios that would yield an improper representation of customer voltage.

CT User Correction Multiplier This feature is included to permit CURRENT

TRANSFORMER ratio correction. It permits the

measured voltage to be adjusted over a 50 to 200% range to compensate for current transformer ratios that would yield an improper representation of customer voltage.

Primary Voltage and Current Multipliers

Primary quantities are displayed when voltage and current multipliers are set into the control. The voltage multiplier is: V (V

)(V

sec

)). For example: If the VT ratio is

corr

mult

= V

pri

/(V

sec

7620/120 = 63.5 and the correction multiplier is +5.8%, the ratio of the voltage multiplier is 60.

The current multiplier is the value of the line CT primary rating divided by 0.2 A.

For a CT primary rating of 1000 A, the multiplier is:

= 1000/0.2 = 5000

mult

The current multiplier setting range is from 20 to 25,000 in increments of 1.

4.8 Tap Position

The Autodaptive® Regulator Control applies to tapchanger designs with a lowest tap position configuration of –16 to a highest tap position configuration of +16.

Tap Position by Keep Track

This feature allows the control to keep track of the presently operating tap.

It is recommended that the indicated tap position be compared to the mechanical tap position indicator at regular intervals, and that the indicated value be corrected, if necessary.

The user initializes the control at a given, known, tap position upon installation by performing the following steps:

1. Determine the actual tap position from the external tap position indicator on the regulator.

2. Using the SLIMcom™ communications program, calibrate the tap position by entering the current tap value under "tap position". The tap position is now calibrated to recognize all subsequent operations so as to “keep-track” of the present tap position.

3. The present tap position is indicated in the Tap Position screen.

The keep-track procedure recognizes tapchanges commanded via:

• The control software.

• The panel switches.

• External contacts.

The tap position stored in memory is not affected by a loss of supply power.

Erase Control Submenu

Retrieve Data Menu

The Retrieve Data menu provides four com- mands: History Data, Outage Data, Tap Sta- tistics, Metering Data, and M-2501 Import.

■ NOTE: These are the only commands which provide print control.

History Data

If a control is connected to your PC, then any history data stored in the control is added to the main history database. If no control is connected, then the main history database is loaded for viewing. The database is capable of storing months to years of data at 0 to 60 minutes intervals. Selection of the History Data submenu dis- plays a history plot of Voltage, VRQF and MWatts waveforms (see Figure 7-3

Outage Data

The Outage Data command allows retrieval of five Autodaptive Regulator Control outages, for a period of 10 seconds each. The outages (see Figure 7-5), are similar to the waveforms shown in Figure 7-3.

Tap Statistics Tap Statistics provides a continuously updated

graph of the taps being made by the control. See Figure 7-4 for an example of the graphic format.

Metering Data Metering Data provides a continuous update of

user-selected data quantities (refer to Metering Setpoints Selection Table).

The Erase Control submenu allows the user to erase all data for History or Tap Statistics. This function erases not only the on-board flash in the control, but all downloaded data files stored on your hard drive. To erase current History and Tap Statistics files from the computer only, use the Erase Data command from the File menu.
