摘要
大型火电厂的一次调频和AGC功能一直以来都是电网稳定频率的重要手段,珠海发电厂2台机组都为700MW亚临界机组,DCS系统采用的是三菱DIASYS Netmation系统。目前AGC投运情况较差,无法长期稳定运行。为快速、高效地应对电网AGC调频服务需求的持续增长,珠海发电厂2台机组通过增加辅助调频外挂控制系统,达到优化改善机组调频性能,改善K值,提升机组调频竞争优势。
The primary frequency modulation and AGC functions of large thermal power plants have always been important means to stabilize the frequency of the power grid.The two units in Zhuhai Power Plant are both 700MW subcritical units.The DCS system uses the Mitsubishi DIASYS Netmation System.At present,the operation of AGC is poor,unable to run stably for a long time.In order to quickly and efficiently respond to the continuous growth of the demand for AGC frequency modulation service,two units of Zhuhai Power Plant added auxiliary frequency modulation plug-in control system to optimize and improve the frequency modulation performance of the units,improve the K value and enhance the competitive advantage of the units in frequency modulation.
