摘要
介绍了珙县电厂超临界直流炉机组一次调频的功能设置,通过对数字电液控制系统(DEH)和协调控制系统(CCS)一次调频速度变动率的合理设置,实现了在一次调频动作时DEH侧快速动作,满足了电网一次调频要求,保证了电网频率稳定和电网优质运行。
The function set-up of primary frequency regulation for the supercritical once-through boiler unit in Gongxian Power Plant was introduced.Depending on the rational setup of the speed variation rate of DEH and CCS for primary frequency regulation,the fast action of DEH side in primary frequency regulation operating process was realized;the primary frequency regulation requirement of the power grid was satisfied;and the frequency stabilization and fine operation quality of the power grid were ensured.
