GE IS200EPSMG1ABB is an Exciter Power Supply Board designed for the Mark VI Turbine Control System. It provides regulated, isolated power to the turbine's exciter field, ensuring precise generator voltage control. This module is critical for reliable and stable power generation in gas and steam turbine applications, featuring robust protection and diagnostics.
Product Specifications
Official Product Designation: This unit is officially designated as an Exciter Power Supply Board, part number IS200EPSMG1ABB, designed explicitly for integration into the GE Mark VI series turbine control system.
Core System Function: The board's primary function is to provide a precisely regulated and isolated DC power output to the exciter field of a synchronous generator. This is a critical function for maintaining automatic voltage regulation (AVR) and overall generator stability.
High-Capacity Power Output: The module is engineered to deliver the high current levels required to directly drive the generator's exciter field, ensuring robust and responsive control of the main generator field current.
Integrated Protection and Diagnostics: The board incorporates comprehensive protective features, including overcurrent and overtemperature protection. It provides detailed diagnostic feedback to the Mark VI controller for real-time system monitoring and fault annunciation.
Robust Industrial Design: Built for maximum reliability in demanding power plant environments, the board operates effectively across a wide temperature range and is designed with high immunity to electrical noise and vibration.
Seamless System Integration: The IS200EPSMG1ABB is designed as a plug-in module for the Mark VI system rack. It communicates directly with the central controller, ensuring fully synchronized operation within the turbine control and protection sequence.
