摘　　要：某1000MW超超临界机组电厂试验综合利用凝结水流量调节、补汽阀调节、低压加热器和高压加热器回热系统蓄能等,在高压调节门全开方式下,当电网低频动作时较快地增加相应负荷,以满足一次调频性能要求,同时不牺牲机组经济性。为满足机组快速响应一次调频需要,同时考虑机组经济性,仙桃项目尝试采用一种新的一次调频控制优化方案:汽轮机高调门与#0、#1高加抽汽调门联合调节。The test of a 1000MW ultra-supercritical unit power plant comprehensively utilizes condensate flow regulation,supplemental valve adjustment,low-pressure heater and high-pressure heater regenerative system energy storage,etc,in the full-open mode of the steam turbine high-profile door,when the power grid is at low frequency action.The corresponding load is increased quickly to meet the performance requirements of the primary frequency modulation without sacrificing the economics of the unit.In order to meet the unit's need for rapid response to primary frequency modulation,and considering the economy of the unit,the Xiantao project tried to use a new control optimization solution for primary frequency control:steam turbine high-profile doorand#0、#1 high extraction steam control door combined regulation.
