摘要
结合西北３３０ｋＶ电网的实际，本文详细分析了取消３３０ｋＶ断路器合闸电阻后的系统合问、重合间过电压及ＭＯＡ吸收能量，得出了大部分３３０ｋＶ线路可以取消断路器合闸电阻的结论。在线路两侧加装ＭＯＡ的情况下，更多的线路可取消断路器的合闸电阻。
According to the practical situations of 330kVpower system in Northwest China and under the conditionof eliminating closing resistors for 330kV circuit breakers,the switching-surge overvoltages and the MOA energy dissipation is analyzed in this paper, and it is proved from theanalyses that the bulk of reclosing resistor for most 330kVcircuit breakers can be eliminated. Installing MOA at bothendes of the transmission line, it is possible for more transmission line to eliminate the closing resistor for 330kV circuit breakers.
