摘　　要：一次调频是火电机组的重要功能,对电网稳定有重要的作用。常规一次调频仅利用锅炉蓄热,在某些工况不能满足一次调频的需求。从机组回热系统及抽汽系统的蓄能原理出发,挖掘机组可利用的综合蓄能。通过特性试验,验证了回热及抽汽系统的蓄能情况,并采用了粒子群算法对综合蓄能对象特性进行了建模与仿真。Primary frequency regulation (PFR)is an important function of thermal power units and plays an important role in power network stability.Conventional primary frequency regulation only uses boiler heat storage,which can not meet the demand of primary frequency modulation in some working conditions.Starting from the energy storage principle of the regenerative system and the extraction system of the unit,the comprehensive energy storage available to the unit is excavated in this paper.The energy storage of the regenerative and extraction system is verified by the characteristic test,and the particle swarm optimization (PSO) algorithm is used to model and simulate the characteristics of the integrated energy storage object.
