北京十三陵蓄能电厂自动准同期装置是监控系统集成的一种同期模件,该模件只能设置一套同期参数,而抽水蓄能电厂存在多种运行工况,不同工况下的同期并网条件并不相同。一套适合发电工况的同期参数,在其它工况下机组并网,会给机组带来一定的电气冲击。文中通过北京十三陵蓄能电厂对其同期控制回路的改造,论述了可选择多套参数的南瑞集团公司SJ-12C同期装置在抽水蓄能电厂中多种工况下同期并网的成功应用,为其他抽水蓄能电厂进行同期回路设计和改造提供了借鉴作用。
The automatic synchronizing device of the Shisanling Pumped Storage Power Plant in Beijing is a contemporaneous module integrated with the monitoring system. The module can only set one set of parameters in the same period. However, the pumped storage power plant has many operating conditions. Under different operating conditions Synchronization and network conditions are not the same. A set of parameters for the same period of power generation conditions, and in other conditions the unit and the grid, will give the unit a certain amount of electrical impact. In this article, through the reconstruction of the control circuit of the Ming Tombs Pumped Storage Power Plant in Beijing at the same period, the success of SJ-12C contemporaneous units with multiple sets of parameters that can select multiple sets of parameters in the same period of grid-connected operation under various working conditions in pumped storage power plants Application, for other pumped-storage power plant for the same period of circuit design and transformation provide a reference.
