摘　　要：介绍了研究和开发的新型节能协调控制系统由锅炉控制负荷,汽机控制压力,调整压力设定值使得汽机高压调门全开,并通过凝结水节流参与负荷调节和优化锅炉燃烧率控制来加快负荷响应,同时应用汽机调门阀限调节技术实现一次调频功能。在基本满足电网AGC变负荷和一次调频功能要求的前提下,实现汽机高压调门全开的新型协调控制方式,提高机组运行经济性,实现节能减排。A new economical coordinated control system has been developed,where boiler controls load and turbine controls pressure.The HP control valves keep open by adjusting pressure set-point.Load changing ability is improved through condensate throttling and optimization for boiler burning rate control.The primary frequency control function is realized with the technique of control valve limit adjustment.So the new coordinated control system helps to improve unit′s economic performance and to attain energy saving and emission reduction,and basically satisfies the requirements for unit′s AGC load change and PFC.
