黑启动方案的空载合闸过电压分析与仿真

Switching Over-voltage Verification and Simulation of Unloaded Line in Black-start Scheme

针对电力系统黑启动过程中的空载合闸过电压问题进行理论分析,并用MATLAB/SIMULINK软件进行仿真,将计算结果和仿真结果进行对比,证明理论分析的正确性,同时提出抑制空载合闸过电压的措施。

This paper carries on the theoretical analysis to switching over-voltage question in the power system black start procedure, and makes the simulation with MATLAB/SIMULINK software,comparising the simulation result with the calculating result,the result shows that the over-voltage theoretical analysis has been proven correct, at the same time, advances the controlling measure to restrain unloaded closing over-voltage.
