摘要
天津国华盘山发电有限责任公司500 MW超临界汽轮机原系统属于电液联合控制,其系统功能和控制精度均存在不足。2007年利用大修的机会对调速系统进行了纯电调改造,为机组的协调控制及AGC功能的实现奠定了基础。
The original governor system of 500 MW supercritical turbine in Tianjin Guohua Panshan Power Generation Co. Ltd. is the electro hydraulic control system. There were defects in the system function and the control accuracy. The DEH improvement was implemented on the occasion of the capital repair of unit, it laid the foundation for the cooperative control of unit and the realization of the AGC function.
