摘　　要：对红雁池二电厂#2机组协调控制系统试验与分析总结基础上,合理使用了前馈及反馈的作用,修改了多执行机构手自动切换逻辑,使系统在实际投运时既能快速对负荷进行响应,同时又能保证无扰切换,机前压力稳定在允许范围内。By analyzing and summarizing coordinated control system （CCS） of Hongyanchi No. 2 power plant unit 2, some improvements on A/M change logic of several actuators has been made by using the feedforward and feedback in CCS logic. By these improvements, this CCS is able to response the load requirements quickly and keeps bumpless transfer at the process. The main steam pressure before governor is stable and is kept in the permitted range.
