摘　　要：城市电缆线路的广泛应用带来了大量的充电功率,在轻负荷时可能导致电网无功功率倒送。文章介绍了变压器无功平衡计算,采用蒙特卡洛模拟法计算不同条件下电缆线路发生无功倒送的情况并进行分析,最后结合具体算例进行分析研究。Widespread application of urban cable lines has brought a large amount of charging power,which may lead to reactive power reversal in power grid under light load.The calculation of transformer reactive power balance was discussed.Based on Monte Carlo simulation method,the reactive power reversal of cable lines under different conditions was calculated and analyzed.Finally,a specific example was analyzed and studied.
