1 Introduction

1.1 Overall Operation

The SIPROTEC 7SJ62/63/64 are numerical, multi-functional, protective and control devices equipped with a powerful microprocessor. All tasks are processed digitally exclusively , from acquisition of measured values up to commands to the circuit breakers. Figure 1-1 illustrates the basic structure of the devices 7SJ62/63, Figure 1-2 illustrates the basic structure of the device 7SJ64.

Analog Inputs The measuring inputs (MI) convert the currents and voltages coming from the instru-

ment transformers and adapt them to the level appropriate for the intern al processing of the device. The device provides four current inputs. Depending on the model, the device is also equipped with three or four voltage inputs. Three current inputs serve for input of the phase currents. Depending on the model, the fourth current input (I may be used for measuring the ground fault current I

(current transformer starpoint)

or for a separate ground current transformer (for sensitive ground fault detection I and directional determination of ground faults).

1.1 Overall Operation

Volt age inp ut s ca n either be use d to measur e the three ph ase-to-g round volt ages, or two phase-to-phase voltages and the displacement voltage ( V

voltage). It is also pos-

sible to connect two phase-to-phase voltages in open-delta connection. The four voltage transformers of 7SJ64 can either be ap plied for the input of 3 phase-

to-ground voltages, one displacemen t volt age (V

voltage) or a further voltage for the

synchronizing function. The analog input quantities are passed on to the input amplifiers (IA). The input am-

plifier IA stage provides high-resistance term inations for the analog input quantities. It consists of filters that are optimized for measured-value processing with regard to bandwidth and processing speed.

The analog-to-digital (AD) stage consists of a multiplexor, an analog-to-digital (A/D) converter and of memory components for the transmission of digital signals to the microcomputer system.

Microcomputer System

Apart from processing the measured values, the microcomp uter system ( μC) also executes the actual protection and control functions. They especially include:

• Filtering and preparation of the measured quantities

• Continuous monitoring of the measured quantities

SIPROTEC 4, 7SJ62/63/64 Handbuch C53000-G1140-C147-A, Edition 07.2015

1 Introduction

• Monitoring of the pickup conditions for the individual protective functions

• Interrogation of limit values and sequences in time

• Control of signals for the logic functions

• Output of control commands for switching devices

• Recording of messages, fault data and fault values for analysis

• Management of the operating system and the associated functions such as data recording, real-time clock, communication, interfaces, etc.

• The information is provided via output amplifiers (OA).

Binary Inputs and Outputs

The computer system obtains external information th ro ug h the bin a ry inp u t/output modules (inputs and output s). The computer system obtains the information from the system (e.g remote resetting) or the external equipment (e.g. blocking commands). Outputs are, in particular, commands to the switchgear units and indications for remote signalling of important events and statuses.

Front Elements With devices with integrated or detached operator panel, information such as messag-

es related to events, states, measured values and the functional status of the device are provided via light-emitting diodes (LEDs) and a display screen (LCD) on the front panel.

Integrated control and numeric keys in conjunction with the LCD facilitate interaction with the remote device. Via these elements all information of the device such as configuration and setting parameters, operating and fault messages, and measured values can be accessed. Setting parameters may be changed in the same way.

In addition, control of circuit breakers and other equipment is possible from the front panel of the device.

Serial Interfaces A serial PC interface on the front panel is pr ovided for local communications with the

device through a personal computer using the operating program DIGSI.This facilitates a comfortable handling of all device functions.

A separate service interface can be provided for remote communication with the device via a personal computer using DIGSI. This interface is especially well suited for dedicated connection of the devices to the PC or for operation via a modem. The service interface can also be used to connect an RTD box (= resistance temperature detector) for entering external temperatures (e.g. for overload protection).

The additional interface (only 7SJ64) is designed exclusively for connection of a RTD-Box (= resistance temperature detector) for entering external temperatures.

All data can be transferred to a central control center or monitoring system via the serial system interface. This interface may be provided with various protocols and physical transmission schemes to suit the particular application.

A further interface is provided for the time synchronization of the internal clock via external synchronization sources.

Further communication protocols can be realized via additional interface modules. Over the operating or service interface you can serve the device (only with 7SJ64)

from a distance or locally with a standard Browser . This can take place during the initial start-up, examination and also during the operation with the devices. For this the SIPROTEC 4 standard "Web monitor" is available.

1.1 Overall Operation

Power Supply The before-mentioned function elements and their voltage levels are supplied with

power by a power supplying unit (Vaux or PS). Voltage dips may occur if the voltage supply system (substation battery) becomes short-circu ited. Usually , th ey are bridged by a capacitor (see also Technical Data).

1 Introduction

1.2 Application Scope

The numerical, multi-functional SIPROTEC 4 7SJ62/63/64 are versatile devices designed for protection, control and monitoring of busbar feeders. The devices can be used for line protection in networks that are grounded, low-resistance grounded, ungrounded, or of a compensated neutral point structure. They are suited for networks that are radial or looped, and for lines with single or multi-terminal feeds. The devices are equipped with motor protection applicable for asynchronous machines of all sizes.

The devices include the functions that are necessary for protection, monitoring of circuit breaker positions, and control of the circuit breakers in straight bus applications or breaker-and-a-half configurations; therefore, the devices can be universally employed. The devices provide excellent backup facilities of differential protective schemes of lines, transformers, generators, motors, and busbars of all voltage levels.

Protective Functions

Non-directional overcurrent protection (50, 50N, 51, 51N) is the basis of the device. There are two definite time overcurrent protective elements and one inverse time overcurrent protective element for phase and ground current. For inverse time overcurrent protective elements, several characteristics of differen t standards are provided. Alternatively, user-defined characteristics can be programmed.

Depending on the version of the device that is or dered, the non-directional overcurrent protection can be supplemented with directional overcurrent protection (67, 67N), breaker failure protection (50BF), and sensitive ground fault detection for high-resistance ground faults. The highly sensitive ground fault detection can be directional or non-directional.

In addition to the fault protection functions already ment ion ed , ot he r pr ot ect i ve fun ctions are available. Some of them depend on the version of the device that is ordered . These additional functions include frequency protection (81O/U), overvoltage protection (59) and undervoltage protection (27), negative sequence protection (46) and overload protection (49) with start inhibit for moto rs (66/68) and motor starting p rotection (48), as well as automatic reclosing (79) which allows dif ferent reclosing cycles on overhead lines. The automatic reclosing system may also be connected externally. To ensure quick detection of the fault, the device is equipped with a fault locator.

A protection feature can be ordered for the detection of intermittent ground faults which detects and accumulates transient ground faults.

External detectors account for ambient temperatures or coolant temperatures (by means of an external RTD-box).

Before reclosing after thre e-pole tripping 7SJ64 can ve rify the validity of the reclosure by voltage check and/or synchronous check. The synchronization function can also be controlled externally.

Control Functions The device provides a control function which can be accomplished fo r activa ting an d

deactivating switchgears via the integrated operator panel, the system inter face, binary inputs, and the serial port using a personal computer with DIGSI.

The status of the primary equipment can be transmitted to the device via auxiliary contacts connected to binary input s. The presen t status (or po sition) of the primar y 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 de vice or the binary inputs and outputs allocated for the switch position indications. Depending on the primary equipment being con-

C53000-G1140-C147-A, Edition 07.2015

1.2 Application Scope

trolled, 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. switchgear interlocking) can be established with the aid of integrated, user-configurable logic functions.

Messages and Measured Values; Recording of Event and Fault Data

The operating messages provide 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 assigned to a number of LEDs on the front cover (allocatable), can be externally processed via output contacts (allocatable), linked with userdefinable logic functions and/or issued via serial interfaces.

During a fault (system fault) important events and changes in condition s are saved in fault protocols (Event Log or Trip Log). Instantaneous fault values are also saved in the device and may be analized subsequently.

Communication Serial interfaces are available for the communication with operating, control and

memory systems. A 9-pole DSUB socket at the front panel is used for local communication with a per-

sonal computer. By mea ns of the SIPROTEC operating sof tware DIGSI, all operation and evaluation tasks can be executed via this user interface, such as specifying and modifying configuration parameters and settings, configuring user-specific logic functions, retrieving operational messages and measured values, inquiring device conditions and measured values, issuing control commands.

Depending on the individual ordering variant, a dditio nal inter faces a re lo ca ted on the rear side of the device. They serve to est ablish an extensive communication with other digital operating, control and memory components:

The service interface ca n be operated via electrical d ata lines or fiber optics and also allows communication via modem. For this reason, remote operation is possible via personal computer and the DIGSI operating sof tware, e.g. to operate seve ral devices via a central PC.

The additional port (only 7SJ64) is designed exclusively for connection of a RTD-Box (= resistance temperature detector) for enteri ng external tempe ratures. It can also be operated via data lines or fibre optic cables.

The system interface ensures the central communication between the device and the substation controller. It can also be operated via data lines or fibre optic cables. For the data transfer S tandard Protocols a ccording IEC 60870 870-5-103 are available via the system port. The integration of the devices into the automation systems SINAUT LSA and SICAM can also take place with this profile.

The EN-100-module allows the devices to be integrated in 100-Mbit-Ethernet communication networks in control and automation systems using protocols according to IEC61850. Besides control system integra tio n, this interf ac e en a ble s DIG S I-c om m unication and inter-relay communication via GOOSE.

Alternatively , a field bus coupling with PROFIBUS FMS is availa ble for SIPROTEC 4. The PROFIBUS FMS according to DIN 19245 is an open communication standard that has particularly wide acceptance in process co ntrol and a utomation engineer ing, with especially high performance. A profile has been de fined for the PROFIBUS com-

munication that covers all of the information types required for protective and process control engineering. The integration of the devices into the power automation system SICAM can also take place with this profile.

Besides the field-bus connection with PROFIBUS FMS, further couplings are possible with PROFIBUS DP and the protocols DNP3.0 and MODBUS. These protocols do not support all possibilities which are offered by PROFIBUS FMS.
