线路限流电抗器对工频过电压的影响
|
摘要
加装限流电抗器使线路的正序及零序阻抗参数发生变化,对线路的工频过电压产生影响。利用电磁暂态计算软件EMTP,研究了江苏苏南500 kV惠泉-梅里线路加装限流电抗器对工频过电压的影响。仿真结果表明:在500 kV惠泉-梅里线路加装限流电抗器可减小线路的工频过电压。
Adding a current-limiting reactor on a line can change the system forward-sequence and zero-sequence impedance parameters, which can further affect the power frequency overvoltage.The electromagnetic transient calculation software EMTP was used to research on the affect of adding a current-limiting reactor on the 500 kV Huiquan ～ Meili lines' power frequency overvoltage.The simulation results show that the 500 kV Huiquan ～ Meili lines with current-limiting reactors can reduce the power frequency overvoltage.
