摘要
随着负荷不断增长,同时由于线路走廊日益紧张,中高压电缆越来越广泛地被应用于大城市的220 kV和110 kV电网中。由于电缆的充电功率比普通架空线路高一个数量级,如何进行无功补偿是一个需要认真研究的课题。针对北京电网中电缆不断增加的情况,探讨分析了合理调节电缆线路产生的充电功率问题,提出了装设感性无功补偿设备的具体方法。
Along with continued increasing power load and shortage of line corridor, medium-high voltage cable was generally used at 220 kV and 110 kV power grid in metropolis. As charging power of cable is about one order of magnitude higher than general overhead line, how to compensate reactive power is a new subject to us. The article aimed at increasing cable application in Beijing Grid, tried to find a way to adjust charging power of cable to a reasonable level, and proposed installation methods of inductance reactive power compensation equipment
