System Overview

The model GCS-407 Generator Control System is designed to control the speed of the four EMD model 16 645E9B diesel engines via a Woodward model PG 12R actuator on each unit using a industry standard Woodward model 2301D Digital Load Sharing and Speed Control. The voltage each of the AC Generator model AB20-6 is controlled using an industry standard Basler model DECS-200 Voltage regulator for each generator. Two modes of syncing the generator with the bus are provided for each unit. The first mode is automatically via an industry standard Woodward GCP-31 Genset Control Package. The second mode is manually via a sync scope and Veri-Sync relay.

Power Systems

The Generator Control System components are powered from new circuit breakers fed from redundant 24 VDC battery chargers and battery banks. Individual Circuit Breakers in the Generator Control Cabinets power each different control component. Each sub system component has a dedicated circuit breaker located in the Generator Control cabinets.

The photo above was taken in Jume 2007. Since that time the generator control bay cabinets have been completed, tested at our facility and shipped to the shipyard in Mississippi for installation and commissioning.
