Binary Inputs and Outputs

Binary inputs and outputs from and to the computer system are routed via the I/O modules (inputs and outputs). The computer system obtains the information from the system (e.g remote resetting) or the external equipment (e.g. blocking commands). Outputs are mainly commands that are issued to the switching devices and messages for remote signalling of events and states.

Introduction

1.1 Overall Operation

Front Elements

Light-emitting diodes (LEDs) and a display (LCD) on the front panel provide information on the functional status of the device and report events, states and measured values. The integrated control keys and numeric keys in conjunction with the LCD enable local interaction with the device. They allow the user to retrieve any kind of information from the device such as configuration and setting parameters, operational indications and fault messages (see also /1/ SIPROTEC 4 System Manual) and to change setting parameters.

Serial Interfaces

A personal computer running the DIGSI software can be connected to the serial the front panel to conveniently operate all device functions.

A separate service interface can be provided for remote communication with the device via a personal computer using DIGSI 4. This interface is especially well suited for a permanent connection of the devices to the PC or for operation via a modem.

All data can be transferred to a central control or monitoring system via the serial protocols and physical arrangements are available for this interface to suit the particular application.

A further interface is provided for sources.

Further communication protocols can be implemented via additional interface modules.

Analog Outputs

Depending on the ordering variant and configuration, ports B and D can be equipped with analog output modules for the output of selected measured values (0 to 20 mA or 4 to 20 mA).

Power Supply

Introduction

1.2 Application Scope

1.2

Application Scope

The digital paralleling devices 7VE61 and 7VE63 of the SIPROTEC 4 family are multifunctional compact devices, which may be used for parallel switching systems and generators. Its technical version warrants a high security during parallel switching. This can be reached by means of the 11/2 channel measurement tech-

nique in device 7VE61 or the two-channel measurement technique in 7VE63 and a special hardware design. Additionally, numerous monitoring functions serve as support.

Except for the synchronizing functions, in the devices 7VE61 and 7VE63 are available optional voltages and frequency functions. Thus, the devices can be used for the protection function and for network decoupling tasks.

The devices are recommended for the different applications: 7VE61:

Synchrocheck monitoring for systems and manual synchronization. In this option a total of 3 synchron-

•

izers can parallel operate.

Parallel switching for systems

•

Systems Disconnection and Automatic Re-synchronization

•

Automatic synchronization of small to medium generators.

•

7VE63:

Operation with increased safety requirements through a two-channel feature

•

Parallel switching for high-voltage and extra high-voltage systems

•

Automatic synchronization of large generators

•

Operation of several synchronizers by a device (up to 8 are possible)

•

Visualization of the condition system through a graphic display and local control.

•

Synchronization Functions

The devices recognize automatically the operating conditions and react depending on the pre-settings.

In the operation mode “Synchrocheck” will be checked the validity of a restart according to different

•

considerations.

In the operation mode “Switching Synchronous Systems” will be determined the frequency difference

•

with high accuracy. The connection will take place if the difference frequency is for a long time near to 0.

If asynchronous conditions are available as in the case of synchronization for generators and systems,

•

thus the speed can bring near automatically at the system frequency and the generator voltage at the system voltage. A considering factor of the circuit breaker closing time is that the generator will be switched to a point of synchronism.

A very high security for recognition of a de-energized line or bus is achieved via the multi-voltage circuit

•

and the multiple inquiries of the voltage. As a result, a connection of the network is trouble-free reestablished.

Protection and Automation Functions

The devices include the following basic functions:

Overvoltage protection U>

Undervoltage protection U<

Vector jump protection Δφ

•

Fast threshold supervision of the voltages (U>; U<)

•

Control Functions

The device is equipped with control functions which operate, close and open, switchgear via the integrated operator panel, the system interface, binary inputs, and using a personal computer with DIGSI software.

The status of the primary equipment can be transmitted to the device via auxiliary contacts connected to binary inputs. The present status (or position) of the primary equipment can be displayed on the device, and used for interlocking or plausibility monitoring. The number of the operating equipment to be switched is limited by the binary inputs and outputs available in the device or the binary inputs and outputs allocated for the switch position indications. Depending on the primary equipment being controlled, one binary input (single point indication) or two binary inputs (double point indication) may be used for this process.

The capability of switching primary equipment can be restricted by a setting associated with switching authority (Remote or Local), and by the operating mode (interlocked/non-interlocked, with or without password request).

Processing of interlocking conditions for switching (e.g. system interlocking) can be established with the aid of integrated, user-configurable logic functions.

Messages and Measured Values; Fault Recording

The indication list provides information about conditions in the power system and the device. Measurement quantities and values that are calculated can be displayed locally and communicated via the serial interfaces.

Device messages can be allocated to a number of LEDs, externally processed via output contacts, linked with user-definable logic functions and/or issued via serial interfaces.

During a generator or network fault (fault in the power system), important events and state changes are stored in a fault annunciation buffer. The instantaneous or rms measured values during the fault are also stored in the device and are subsequently available for fault analysis.

Introduction

1.2 Application Scope

Communication

Serial interfaces are available for the communication with operating, control and memory systems.

Front Interface

A 9-pin DSUB socket on the front panel is used for local communication with a personal computer. By means of the SIPROTEC 4 operating software DIGSI, all operational and evaluation tasks can be executed via this ator interface, such as specifying and modifying configuration parameters and settings, configuring userspecific logic functions, retrieving operational and fault messages and measured values, readout and display of fault recordings, querying of devices statuses and measured values.

Rear Interfaces

Depending on the individual ordering variant, additional interfaces are located at the rear side of the device. They serve to establish an extensive communication with other digital operating, control and memory components:

The this reason, remote operation is possible via personal computer and the DIGSI operating software, e.g. to operate several devices via a central PC.

The can be operated via data lines or fibre optic cables. Several standard protocols are available for the data transfer:

2.1.1

General

The settings associated with the various device functions may be modified by using the operating or service interface in DIGSI. The procedure is set out in detail in the /1/ SIPROTEC 4 System Manual. For changing configuration parameters in the device, password no. 7 (for parameter set; default setting: 000000) is required. Without the password, the settings may be read, but may not be modified and transmitted to the device.

The settings associated with the various device functions, limit values, etc. can be modified using the controls on the front panel of the device or by using the operator interface with DIGSI in conjunction with a personal computer. Password No. 5 (for single parameter; default setting: 000000).

Device

The device can issue a serie of general annunciations about itself and the substation. These annunciations are listed in the following information list. Most annunciations are self-explanatory. The special cases are described below:

Reset: Device is reset on each Power ON. Initial Start: Initial start occurs after initialization of the device by DIGSI. Restart: Restart occurs after loading a parameter set or after reset.

The indication of messages masked to LEDs, and the maintenance of spontaneous messages, can be made dependent on whether the device has issued a trip command. In this situation, messages are not reported, if one or more protective functions have picked up on a fault, but a trip signal has not been issued yet by the 7VE61 and 7VE63, because the fault was cleared by another device (for example, outside the own protection range). These messages are then limited to faults in the line to be protected.

2.1.1.1

Spontaneous Fault Display

Resetting stored LEDs / relays

Setting Notes

After a fault has occurred, the device display spontaneously shows the most important fault data. In address 610 FltDisp.LED/LCD you can select whether the spontaneous fault display is updated for each fault (Target on PU) or only for faults that included a trip (Target on TRIP).

For devices with graphical display use parameter 611 Spont. FltDisp. to specify whether a spontaneous fault display will be shown automatically YES) or not (NO). For devices featuring a text display such displays will always appear a power system fault.

[logik-spondanmeld-display-081024, 1, en_GB]

Figure 2-1 Generation of spontaneous fault indications on the display

A new pickup will generally erase any stored LEDs/relays so that only the latest fault information is displayed at any time. A time can be set in address 615 T MIN LED HOLD during which the stored LEDs and relays will not be deleted. Any information occurring during that period of time will be linked via OR.

The option Target on TRIP in address 610 FltDisp.LED/LCD allows you to delete the information of the most recent fault stored on LEDs and relays provided that this fault has not resulted in a trip command of the device.
