Abstract

In this article, the offshore production platform´s two 25-MW turbine generator units were evaluated to determine the safe operating limits of the units if the entire load is to be carried by one generator. A case study is performed to determine whether load shedding will be necessary if only one generator is in operation. The generator reactive capability curve was constructed based on limited data due to the age of the generators. The real power output capability of the turbine-generator combination was evaluated based upon the data provided. The generator was rated in accordance with British Standard BS.2613/1957. The analysis was based upon the requirements the superseding standards, International Electrotechnical Commission (IEC) 60034-1 (2004) and IEC 60034-3 (2005).
