摘　　要：随着如风电、太阳能等可再生能源的并网,使得火电机组需要进行深度调峰且快速响应调度指令。然而,传统的负荷调节控制方法难以使得机组应对调度指令的频繁变化。火电机组热网包含着大量的管道与热力设备,它们均具有很强的蓄热能力,合理利用其蓄热可在短时间内提升机组负荷响应速度。针对上述问题,对利用热网蓄能辅助供热机组负荷调节进行了研究,并设计了基于调度指令与负荷响应偏差的协调控制系统。仿真结果表明,所设计的协调控制系统能够提高机组负荷响应调度指令的能力,且保证供热压力的稳定。With the gird-connection of renewable energy sources such as wind and solar,the coal-fired units are required to participate in the deep-peak-shaving and respond quickly to automatic generation control(AGC)command.However,the traditional control method of load regulation is difficult to make the unit handle with the frequent variations of the AGC command.The thermal network consists of tubes and thermal equipments,which has strong ability to store energy.The rational utilization of the energy storage can improve the speed of load in a short time.To solve this problem,this paper studied on the load regulation of the heat supply unit assisted by the heat storage in the thermal networks,and designed the coordinated control system(CCS)based on the deviation between the load of the unit and the AGC command.Simulation results illustrate that the proposed CCS can improve the ability of the unit to respond the AGC command and guarantee the stability of supply steam pressure.
