Condensing Steam Turbine Control System

A Westinghouse turbine with an electrical rating of 44.5MW was upgraded at a coal power utility in Panama. The mechanical governing system upgrade was considered due to the following reasons: poor control response, hard to adjust and it was very expensive to service and maintain. The customer wanted automation of the turbine governor to improve system performance and maximize unit availability and efficiency.
