摘要
2019年,西南电网与华中电网实现异步联网运行。结合西南电网异步联网后水电机组调速器开度模式一次调频运行情况,介绍了异步联网前后西南电网水电机组调速器功率开度模式下功率调节和一次调频实现方式,分析了目前调速器开度模式一次调频存在的问题,提出了调速器区分机组功率变化一次调频成分和监控有功调节成分方法,探讨了调速器开度模式一次调频优化策略方案,研究结论可供水电机组调速器开度模式功能完善参考。
In 2019,Southwest power grid was asynchronously interconnected with Central China power grid.Combined with operation condition of primary frequency modulation in governor opening mode of hydropower unit,this paper introduces the power regulation and primary frequency modulation of hydropower units before and after asynchronous networking of southwest power grid,analyzes the problems existing in the primary frequency modulation of the governor opening mode,puts forward a method for distinguishing the primary frequency component and monitoring regulation component of hydropower power variation in governor,discusses the optimization strategy of primary frequency modulation in governor opening mode.The conclusions can be used as a reference for improving the function of governor opening mode of hydropower units.
