Details
The IS200ERSCG1A is an Exciter Regulator Static Converter board developed by GE used within EX2100 Excitation control.
The board interfaces with different boards depending in whether it is used in simplex or redundant applications.
This system is designed for retrofit and new control of hydro, steam, or gas industrial turbine systems, typically connected to GE’s Mark VI Integrated Control System.
The ERSC board provides the pulse width modulated (PWM) dc output current andthe field discharge function for the regulator control.
These two functions are definedas the power conversion module (PCM).The PCM consists of an integrated IGBT inverter module that contains six IGBTsconnected in a 3-phase inverter configuration.
Two of the six IGBTs are used to cre-ate the PWM dc output for field excitation. A third IGBT is used to discharge the dclink capacitors into an external dynamic discharge (DD) resistor.
Maximum output is20 A dc continuous, 30 A dc for 10 seconds. Input power is either rectified ac, dcfrom a station battery, or both.A relay, K3, is provided to bypass the dc link charging resistor.
The dc link chargingresistor provides a soft charge on initial power up for the dc link capacitors.
