唐湖电厂1号机组AGC功能无法投入原因分析及处理

Analysis on the Malfunction of the No.1 Power Generating Unit AGC in the Tanghu Power Plant and Treatment

针对唐湖电厂1号机组在实际运行中MCS(模拟量控制)系统存在的问题,对其控制逻辑及执行机构现状进行分析研究,优化控制系统策略,保证了机炉协调控制系统的调节品质,最终实现了机组AGC功能的正常投入。

This paper analyzes the problems in the MCS of the No. 1 generating unit experienced in operation. Based on study and analysis on the control logic and the actuator,an optimal control strategy is given. Through the application of the proposed strategy the control quality of the unit-boiler coordination control system is guaranteed and then the AGC is put into service.
