GE IS200FHVBG1A

Part Number IS200FHVBG1A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockIS200FHVBG1A is a high-voltage gate input board developed by General Electric for the EX2100 excitation control system. The GE Energy EX2100 Excitation Control System is a cutting-edge platform for generator excitation, which includes transformers, numerous controllers, power bridges, and a protective module. IS200FHVBG1A Features The EX2100 Excitation Control (EX2100 or exciter) generates the field excitation current used to control the generator's AC terminal voltage and/or reactive volt-amperes. It is a complete static excitation system designed for generators on new and retrofit steam, gas, and hydro turbines. The exciter is a modular system that can be assembled to provide various output currents and levels of system redundancy. Options include power from a potential, compound, or auxiliary source, with single or multiple bridges, warm backup bridges, and simplex or redundant controls. High Voltage Interface The High Voltage Interface (HVI) includes the AC and DC buses and line filter fuses. It also features two terminal boards that provide bridge feedback to the control and the EXAM board. Software Overview The exciter control code is executed by microprocessor-based controllers. The software comprises modules (blocks) that work together to provide the necessary system functionality. Variables are stored in random-access memory (RAM), while block definitions and configuration parameters are stored in flash memory (RAM). Traditional analog controls are emulated by the exciter application software. It uses an open architecture system with a library of preconfigured software blocks from the toolbox. Individual blocks, such as logic gates, proportional-integral (P.I.) regulators, function generators, and signal level detectors, perform specific functions. The control switches between two modes: generator voltage regulation (Auto Regulation) and direct control (voltage or current, depending on the application). The control includes generator protection functions such as over and under-excitation limiting, power system stabilization, and V/Hz limiting. Using the toolbox, the blocks can be interrogated while the exciter is running. During operation, dynamically changing I/O values of each block can be viewed, which is useful for startup or troubleshooting.HIGH VOLTAGE GATE IN (*2)
