摘要
随着大气污染防治重点输电通道的建设,出现了点对网输电通道,对于电网的安全稳定运行带来了新的挑战。基于2019年夏平运行方式数据,利用电力系统仿真软件,对电网运行的稳定性进行分析。研究输电通道扩建、线路串补投退、设备检修等对电网稳定性的影响,提出对发电厂输电功率及电压的要求。
With the construction of key transmission channels for air pollution control,point-to-network transmission channel appears.It brings new challenges to the safe and stable operation of power grid.Based on the data of peak operation data in the summer of 2019,it analyzes the stability of power grid operation using power system simulation software.By studying the influence of transmission channel expansion,operation and exit of line series compensation device and equipment overhaul,the requirements of transmission capacity and voltage for power plant are proposed.
