摘要
大型火电机组目前普遍采用了超速保护控制系统(OPC),其定值一般取自出厂值。文中以实际电网为例,分析了孤岛运行过程中,因为OPC定值选择不当给电网造成的影响,并指出了OPC定值选择需要注意的几个问题。
Large size turbine units generally have over speed protection control system, the setting value is general from factory value. This paper takes the actual power network as an example, analyzes the island in the process of operation, and finds the At last, OPC fixed value choices of factors need to pay attention
