Introduction

Powerware 9330 UPS true double conversion online power protection can be utilized to prevent loss of valuable electronic information, minimize equipment downtime, and/or minimize the adverse effect on equipment production due to unexpected power problems.

The Powerware UPS System continually monitors incoming electrical power and removes the surges, spikes, sags, and other irregularities that are inherent in commercial utility power. Working with your building’s electrical system, the UPS System supplies clean, consistent power that your sensitive electronic equipment requires for reliable operation. During brownouts, blackouts, and other power interruptions, internal and optional external battery strings provide emergency power to safeguard your operation.

The UPS system is housed in free-standing cabinets. The cabinet sections line up and match in style and color, and have safety shields behind the front panels for hazardous voltage protection. The following illustrations depict a typical Powerware 9330 (10 kVA--- 20 kVA) UPS System and a typical Powerware 9330 (25 kVA---40 kVA) UPS System

Understanding UPS Operation

6.1 Looking Inside the UPS System

The Powerware 9330 is a continuous duty, solid-state, transformerless (at 208 VAC), three phase, true online system that provide conditioned and uninterruptible AC power to the UPS systems output. The UPS supports process control, data processing, telecommunications/PBX, research, and non ---patient medical equipment. The Powerware 9330 maintains power to the critical loads during commercial electrical power brownout, blackout, overvoltage, undervoltage, and out-of-tolerance frequency conditions.

The basic system consists of a rectifier, battery charger, DC booster, inverter, monitoring/operation control panel, integrated communications server, and microprocessor controlled (DSP) logic.

In this manual, the power required by your equipment is called the critical load.The UPS supplies the critical load with conditioned power that is synchronized with your utility power. Figure 6--- 1 shows the main elements of the UPS.

Figure 6 ---1. Main Elements of the UPS System

If utility power is interrupted or falls outside the parameters specified in Chapter 15, “Product Specifications,” the UPS uses a backup battery supply to maintain power to the critical load for a specified period of time or until the utility power returns. Forextendedpoweroutages,theUPSallowsyoutoeithertransfertoanalternative power system (such as a generator) or shut down your critical load in an orderly manner.

The emergency bypass consist of a continuous duty static switch, and backfeed protection contactor (K5). The backfeed protection contactor is located in series with the static switch. For manual transfers to bypass, the static switch is also used. The static switch is armed and ready during both types of transfers.

A wraparound Maintenance Bypass switch provides a means of isolating the UPS Power Processsing Unit (PPU) for servicing, while still suppling power to the critical load.

The operation of the UPS system is described in greater detail in the following paragraphs.

6.2 UPS Modes

The UPS system functions automatically to supply AC electrical power to the critical load. There are four standard operation modes:

· In Normal mode, the critical load is supplied by the inverter, which derives its power

from rectified utility AC power. In this mode, the battery charger also provides charging current for the battery, if needed.

· In B attery mode, the battery provides DC power, which maintains inverter operation.

The battery supports the critical load.

· In Bypass and High Efficiency mode, the critical load is directly supported by utility

power.

· In Maintenance Bypass mode, the critical load is directly supported by utility power, but

the UPS can be shut down for maintenance. This is accomplished by the operator moving the Maintenance Bypass Switch to Bypass.

The UPS continually monitors itself and the incoming utility power, and automatically switches between these modes as required, with no operator intervention, except for the Maintenance Bypass mode. The sophisticated detection and switching logic inside the UPS ensures that operating mode changes are automatic and transparent to the critical load. The UPS switches operating modes in response to these system events:

· A command is an intervention that is externally initiated by an operator or by some site

action. A command causes the UPS to switch operating modes; it usually does not require any further action by you.

· A notice is a minor system event that may or may not require your attention.

· An alarm is a system event that requires immediate operator intervention.

System events, alarm horns, and indicator lights are described in Chapter 11, “Responding to System Events.”

The following descriptions provide the differences in UPS operating modes.

Figure 6 ---2. Path of Current Through the UPS in Normal Mode

During normal UPS operation, power for the system is derived from a utility input source through the input breaker CB1 and contactor K1. ”Normal” appears on the front panel and indicates the incoming power is within voltage and frequency acceptance windows. Three phase AC input power is converted to DC using a full--- wave, six---pulse, solid ---state rectifier block which supplies unregulated DC voltage to a boost converter which in turn supplies a higher and regulated DC voltage to the inverter. The battery is not charged directly from the unregulated rectifier. Instead, a separate battery charger is used to maintain the proper charge level on the battery during normal operation.

164201300 REV. G 061502

Page 79

The battery charger derives its input from the unregulated DC output of the rectifier and provides regulated DC voltage and charge current to the battery. The battery charge condition is monitored by the UPS and reported by status indicators located on the LCD monitor panel. The battery is always connected to the UPS and ready to support the inverter should the utility input become unavailable.

The DC boost converter derives power from the unregulated DC rectifier and produces an elevated and stable DC voltage and current source for the inverter . The boost converter also establishes the systems output neutral for supporting single phase AC loads from any phase of the inverter output. The output neutral of the system is connected with the required neutral supplied at the utility bypass input and should never be bonded to ground at the modules output.

The inverter produces a three phase AC output to a customers load without the use of a transformer. The inverter derives power from the boost converters regulated DC and utilizes IGBT devices and pulse---width modulation (PWM) to produce a regulated and filtered AC output. The AC output of the inverter is delivered to the system output through the output contactor (K3).

If the utility AC power is interrupted or is out of s pecification, the UPS automatically switches to Battery mode to support the critical load with no interruption. When utility power returns, the UPS returns to Normal mode.

If the UPS becomes overloaded or unavailable, the UPS switches to Bypass mode. The UPS automatically returns to Normal mode when the overload condition is cleared and system operation is restored within specified limits.

If the UPS suffers an internal failure, it switches automatically to Bypass mode and remains in that mode until the failure is corrected and the UPS is back in service.

Figure 6 ---3. Path of Current Through the UPS in Bypass Mode

In Bypass mode, the output of the system is provided with three phase AC power directly from the system input. While in this mode, the output of the system is not protected from voltage or frequency fluctuations or power outages from the source. Some power line filtering and spike protection is provided to the load but no active power conditioning or battery support is available to the output of the system in the Bypass mode of operation.

6--6

The internal bypass is comprised of a solid state silicon controlled rectifier (SCR) static switch (SSW), and a back feed protection contactor (K5). The static switch is rated as a continuous duty device that is used anytime the boost converter and inverter is unable to support the applied load. The static switch is wired in series with the back feed protection contactor and together they are wired in parallel with

Powerware 9330 (10 kVA--40 kVA) Installation and Operation

164201300 REV. G 061502

Page 81

the inverter rectifier. The static switch being an electronically controlled device can be turned on immediately to pickup the load from the inverter while the inverter output contactor K3 opens to isolates the inverter. The back feed protection contactor is normally always closed ready to support the static switch unless the bypass input source becomes unavailable.

During an outage, transfers to bypass are prohibited and for the safety of those who may be working on the power lines upstream from the UPS, the back feed protection contactor is opened, preventing system output voltage from bleeding across the static switch snubber components to the bypass input source.

If the inverter is unable to support the load on the output of the system, to ensure the load remains energized, the UPS will transfer the load to the internal bypass. The output of the system will be transferred automatically to the internal bypass if any of the following abnormal conditions occur on the output of the system: If the output of the system exceeds acceptable voltage tolerances; System is overloaded; Inverter failure. The transfer is initiated by turning on the static switch and opening the output contactor K3. This kind of transfer is normally referred to as a Make--- Before---Break transfer. The transfer should take place in less than 4 mS (quarter cycle) to ensure loads on the systems output are not interrupted. The static switch remains on until either the inverter is able to support the system output or the unit is placed into a maintenance position where repairs can be made.

If the UPS initiates its own transfer to bypass for any reason other than operator intervention, the UPS will attempt to restart the inverter (if not running already) and attempt a retransfer back on line to support the output of the system. Three attempts will be made within ten minutes to bring the inverter back on--- line automatically before the UPS will lock out any further attempts. After three attempts have been made, the UPS will remain in bypass and an alarm condition will be enunciated. The UPS can also be transferred to bypass using the front panel controls.

Bypass mode is a normal operating mode, and not an alarm condition. However, if the UPS is unable to return to Normal mode following an automatic transfer to Bypass mode, an alarm condition is recorded.

In High Efficiency mode, the output of the system is provided with three phase AC power directly from the system bypass input. Some power line filtering and spike protection is provided to the load but no active power conditioning or battery support is available to the output of the system in the High Efficiency mode of operation. However if the bypass source falls outside of a predetermined voltage or frequency window, the system forward transfers and the inverter assumes the load. The transfer takes place in less than 4 ms (quarter cycle), to ensure loads being fed by the system output are not interrupted.

The internal bypass is comprised of a solid state silicon controlled rectifier (SCR) static switch (SSW), and a back feed protection contactor (K5). The static switch is rated as a continuous duty device. The static switch is wired in series with the back feed protection contactor and together they are wired in parallel with the inverter.

In the High Efficiency mode, the static switch is turned on to supply the majority of the load current directly to the load while the Inverter remains on line, ready to assume suppling the load.

Figure 6 --- 5. Path of Current Through the UPS in Battery Mode

During a utility power failure, the rectifier no longer has an AC utility source in which to supply the DC output current required to support the battery charger and boost converter. The input contactor (K1) is opened, the battery charger is turned off, and battery SCR (Q10) and battery contactor (K2) both receive signals to turn on enable to supply battery power to the system. Because the battery SCR is an electronic device, it supplies momentary battery power to the system during the time it takes the contacts of K2 to close. Energy stored in the battery is supplied instantaneously to the boost converter so that the inverter and customers load can be supported without interruption. If the bypass is common with the rectifier input, the Feed Back Protection contactor (K5) will also open. The opening of contactors K1 and K5 prevent static system voltages from bleeding backwards through the static switch and rectifier snubber components and re ---entering the input source.

While in battery mode, the UPS will enunciate an audible horn, light a visual indicator lamp on the front panel (System Normal, On Battery), and make an entry into the alarm event history. As the battery discharges, the boost converter and inverter constantly makes minute adjustments enable to maintain a steady output. The UPS will remain in this operating mode until the input power to the rectifier is again within the specified voltage or frequency acceptance windows.

164201300 REV. G 061502

6--9

Page 84

If the input power fails to return or is not within the acceptance windows required for normal operation, the battery will continue discharging until a DC voltage level is reached where the inverter output can no longer support the connected loads. When this occurs, the unit will issue another set of audible and visual alarms indicating SHUTDOWN IMMINENT. Unless the rectifier has a valid input soon, the output will only be supported for 2 minutes before the output of the system shuts down. If the bypass source is available, the system will transfer to Bypass instead of shuting down.

If at any time during the battery discharge the input power becomes available again, contactors K1 and K5 are closed and the rectifier will begin to supply DC current to the boost converter and inverter. The battery contactor K2 is opened while the battery charger is turned back on to begin recharging the battery. At this point, the unit returns to normal operation. Depending on the amount of load on the system and the duration of the battery discharge, battery current limit alarms may be seen for a short time due to the current required to recharge the battery.

The systems total operating time on battery will depend on many factors. Some factors that affect battery support times are battery type and capacity, number of parallel strings, environmental temperatures, age of the battery, and fluctuations in load demand during the discharge. The greater the load, the less support time the battery will have. Decrease the load, and the battery support time will generally increase.

6.2.5 Test and Maintenance Bypass Modes

An internal maintenance switch is used to safely supply utility power to the system output during periods of maintenance or repairs. Before this switch is used, the UPS should be transferred to bypass and the Power Processing Unit (PPU) should be turned off. This switch has three positions: UPS (normal), TEST, BYPASS. The bypass source supplies the commercial AC power to the load directly.

While on internal bypass, when a user rotates the maintenance switch from the UPS position to the TEST position, the load is wrapped around the UPS, while power is still supplied to the internal bypass. The static switch remains energized to support the load should the user rotate the switch back to the UPS (normal) position. When the maintenance switch is rotated back to the UPS position from the TEST position, the load is switched back to the internal bypass. If the maintenance switch is rotated to BYPASS instead of to UPS from the TEST position, the load remains wrapped around the UPS and power is removed from the entire upper half of the unit allowing service work to be completed on the unit safely.

Figure 6---6 shows the path of electrical power through the UPS system when operating in Test mode and Figure 6---7 shows the path of electrical power through the UPS system when operating in Maintenance Bypass mode.

CAUTION: The critical load is not protected while the UPS is in Test or Maintenance Bypass modes.

6.3 Functional Description

The UPS is a true online unit with a series power train. An uncontrolled rectifier feeds a boost converter, which in turn powers the inverter. The bypass utilizes a static switch and a maintenance bypass switch is internal to the unit. The unit input is 3---wire in (plus ground) at the rectifier and 4---wire in (plus ground) at the bypass, and 4 wire output. The unit does not incorporate any galvanic isolation, input to output. The battery string comprises 144 cells (288 volts nominal) and is charged via a buck or boost converter powered from the raw DC IN from the input rectifier.

6.3.1 Input Rectifier

The Input Rectifier is a full wave bridge uncontrolled rectifier, which produces an unregulated DC IN Bus. The raw DC at this point will be approximately 290 VDC. A pre--- charge system pre--- charges the DC IN Bus prior to the input contactor being closed.

164201300 REV. G 061502

Page 87

6.3.2 Boost Converter and Neutral Regulator

A Boost Converter converts the raw DC IN to a regulated DC Link of approximately 400 volts DC. It is operated in current mode and controlled using a variable frequency modulation technique at approximately 18---20 kHz. An artificial neutral is generated by the Neutral Regulator (Buck/Boost configuration in current mode control), which balances the center point to 1/2 the DC Link (+/--- 200 Volts).

6.3.3 Inverter and Filter

The Inverter is a traditional (current mode controlled) hard ---switched IGBT 3---phase topology. The IGBTs are modulated by a variable frequency, current--- mode control technique at approximately 18 ---20 kHz. An output filter filters out the high frequency switching components (line to neutral).

6.3.4 Battery and Battery Charger

The Battery is comprised of a string of 144 cells, made up of twenty---four 12 volt Battery blocks. The Battery Charger is configured as a simple Buck or Boost current mode controlled converter (mode auto selected based on I out), powered by the raw DC IN, which regulates the battery charge voltage/current. The unit utilizes Advanced Battery Management (ABM) technology, which essentially isolates the Battery from the electrical environment, except for periodic charging or reserve mode operation, extending its life.
