LM2500燃气轮机发电机组双同期点并网的研究

Research on Dual Simultaneous Point Connection of LM2500 Gas Turbine Generator Sets

航改型燃气轮发电机组的设计运用中,同期并网是至关重要的一步。在以往大量实际应用案例中,绝大多数燃气轮发电机仅设计了单点同期并网的运行方式,即利用发电机出口断路器进行同期并网。随着分布式能源站市场的发展,航改型轻型燃气轮发电机组的应用越来越广泛,单点同期的设计已经不能满足客户的需求,因此,在传统单点同期方式基础上增加利用高压断路器作为备选同期控制点的设计与研究成了必然趋势,具有很高的实用价值。

Simultaneous grid-connection is a very important step in the design and application of navigation modified gas turbine generator sets.In a large number of previous practical application cases,the vast majority of gas-turbine generators only designed the operation mode of single-point synchronous grid-connection,that is,synchronous grid-connection by generator outlet circuit breaker.With the development of the distributed energy market,the application of the navigation light gas turbine generating sets for module is more and more widely,the design of the single point at the same time already can't meet customer demand,therefore,based on the traditional single point at the same time increase the use of high voltage circuit breaker as alternative design and research has become inevitable trend of the control points at the same period,and has a high practical value.
