2020年上海并网发电机组跳闸对电网的影响分析

Influence Analysis of Grid-connected Generator Sets Tripping on Power Grid in Shanghai in 2020

重点整理汇总了2020年度上海地区发生的并网主力发电机组跳闸事件,根据电网运行数据,分析了发电机组跳闸对电网频率和潮流的影响。希望借此提供经验教训,实现尽可能地避免大机组故障导致电网频率下跌和潮流越限,保障了电网的安全运行稳定性。

This paper summarizes the tripping events of grid-connected generator sets in Shanghai in 2020.Based on the grid operation data,the influence of generator sets tripping on power grid frequency and power flow is analyzed.It is hoped that the experience and lessons can be provided to avoid the power network frequency drop and power flow overrun caused by large unit failures as far as possible,so as to guarantee the safe operation and stability of the power grid.
