General Electric DS200ADGIH1A DS200ADGIH1AAA Auxiliary Interface Board

GE DS200ADGIH1A/DS200ADGIH1AAA is the Auxiliary Interface Board of GE Mark V series, which is an auxiliary DC 2000V generator interlocking/control board. This module is mainly used to protect the generator excitation and unit operation in the high-voltage DC (2000V) auxiliary system. The DS200ADGIH1A component is usually installed in the excitation cabinet, generator control panel, auxiliary switchboard, etc.

Function & Features

• Input power: usually comes from the power station battery or dedicated DC bus, providing high-voltage DC for the static excitation system (such as thyristor rectifier bridge) to directly drive the generator excitation winding.

• Fast fault triggering: When the DC system is overvoltage (ANSI 59), overcurrent (ANSI 40), or ground fault (ANSI 64), DS200ADGIH1A/DS200ADGIH1AAA immediately sends a trip signal to the gas turbine control system (such as Mark VIe).

• DS200ADGIH1A/DS200ADGIH1AAA interlock protection:

1. Excitation voltage interlock: Before the generator circuit breaker is closed, it must be ensured that the excitation voltage has been established.
2. Excitation input conditions: rated speed of the unit, closed excitation circuit breaker
