1 Comprehensive Feeder Protection FCOMP FEEDER CONTROL METERING PROTECTION RELAY

2 Larsen & Toubro (L&T) is a technology-driven company that infuses engineering with imagination. The Electrical & Automation Group of L&T offers a wide range of advanced solutions through its state-of-the-art products backed by world-class in-house capabilities in technology development customer support. For complete feeder protection of air, vacuum or gas-insulated circuit breaker operated feeders in medium and low voltage switchgear assemblies, L&T offers a comprehensive Feeder Control Metering Protection Relay the FCOMP. ABOUT FCOMP The FCOMP combines the ruggedness of conventional feeder protection and the versatility of advanced feeder protection features, annunciations and metering in MV and LV switchgear assemblies into one single, simple-to-configure, communicating module with a large color display. It is scalable, modular and of the right size to cater to your varied feeder protection requirements. To make it suitable for the often dusty and corrosive environs of substations (as in process industries and petrochemical complexes), the FCOMP has a conformal coating on its hardware. User-friendly options and features Universal auxiliary power supply of VAC / VDC o o Operating temperature range of -20 C to 85 C Current-based metering and protection with optional scalability for voltage-based metering and protection built into a single unit Reduced and simplified wiring(especially in auto bus transfer schemes) and reduced dependence on auxiliary components in different schematics through varied DI/DO combinations Facilitation of reconfiguration of auto bus transfer conditions /interlocks, configuration of load shedding and load-sharing, reverse interlocking, conditions for tripping and closing of the circuit breaker, annunciation and status exchange. Six configurable pushbuttons for control and 2 configurable LEDs for indication Advanced substation communication protocol options, viz.: Modbus RTU, Profibus, IEC Modbus TCP/IP, IEC 6850 Scaled up substation communication network architectures with redundancy for IED communications through dual Rj45 and FO(SC/ST) ports for ethernet communication and dual RS485 ports for serial communication Easy connection with a computer through the default USB 2.0 port Easy relay configuration through the indigenous interface software, COMPfigurator, which is provided with configuration settings, communication settings, protection settings, gate logic, latches, timers, event recording and disturbance recording. It allows for online and offline creation of settings files for uploading and downloading to the relay. 4 setting groups, multiple stages in each protection settings and user selectable option on protection source between Fundamental Metering and RMS metering.

8 INTERFACE SOFTWARE The COMPfigurator is a specialized software designed to interface with the FCOMP. FCOMP parameters can be configured, metered, monitored through the COMPfigurator. The FCOMP settings file can be generated by the COMPfigurator by either of these methods: Online mode (FCOMP-powered on and connected with the COMPfigurator ) Offline mode (FCOMP disconnected). The settings file is generated with FCOMP disconnected and downloaded later onto it. The settings file comprises the following configurations which can be modified as per user requirement: General settings (CT ratio, PT ratio, sync input, DIO, AIO, phase rotation, nominal freq, etc.) Protection settings (All current and voltage-based protections) Pushbuttons LEDs Digital output, analog output Event record Pre- and post-fault settings of disturbance record Single line diagram The COMPfigurator can also be used for real time / online metering of: Analog Data: Current, Voltage, Frequency, Power, Power factor Digital Data: Digital input status, digital output status, electrical fault status The COMPfigurator can also be used to monitor and record parameters like event history, sequence of events (024), disturbance record (64 samples / cycle x 6 channels) and hour meter. The COMPfigurator has an option to save the setpoint files file and event records, as required, with password protection.

9 COMPlogic The COMPlogic is part of the COMPfigurator software. It is used to programme the FCOMP to tailor the control and operation of the circuit breaker. The COMPlogic includes: Arithmetic operation (+, -, >, <, =) Logic Gate (AND, OR, NOT) Timer (Pick up, Drop out) Latch 52 lines for control equations Note: For details of sample control equations to implement schematics, refer to the FCOMP operation manual.
