Details
IS200ERDDH1A is a Dynamic Discharge board devloped by GE, Used in the EX2100 Regulator Control, simplex, and redundant applications.
One ERDD is installed in the IS200ERBP Exciter Regulator Backplane (ERBP) and interfaces with the IS200ERIOH A Exciter Regulator I/O board (ERIO) and the Exciter Regulator Static Converter board for simplex applications (ERSC).
In redundant applications, one ERDD is installed in the ERBP (M1), while the other is installed in the Exciter Regulator Redundant Backplane (ERRB, M2/C) and interfaces with the ERIO, ERSC, and the Exciter Regulator Redundant Relay board.
The ERDD is used in the EX2100 Regulator Control, simplex and redundant applica-tions. For simplex applications, one ERDD is mounted in the ERBP and interfaceswith the ERIO and the IS200ERSC Exciter Regulator Static Converter board(ERSC).
In redundant applications, one ERDD is mounted in ERBP (M1) and asecond ERDD is mounted in ERRB (M2/C) and interfaces with the ERIO, ERSC,and the IS200ERRR Exciter Regulator Redundant Relay board (ERRR).
The ERDD provides the following major functions:
•Gate drive control for field excitation
•Dynamic discharge to control excessive dc link voltage
•Bridge feedback to monitor dc link voltage, output shunt current, output fieldvoltage, bridge temperature, and IGBT gate drive status (power supplies and de-saturation conditions)
•Control of the de-excitation relay (K41) in simplex applications or control of thecharging relay (K3) in redundant applications.
