针对煤矿配电网无功优化存在的问题,综合考虑煤矿配电网负荷特点以及传统无功补偿装置的优缺点,提出利用静止无功发生器SVG以及电容器组配合实现配电网无功优化的两阶段无功优化方法.两阶段分别以有功网损最小和电压谐波畸变率最小为目标,根据灵敏度法确定补偿位置,运用改进的粒子群算法进行无功补偿容量的优化配置.研究结果表明:配电网的有功损耗明显下降,电压水平明显改善,为配电网无功优化提供了一种灵活高效,易于实现的有效方法.
Aiming at the problems existing in reactive power optimization of coal distribution network, considering the load characteristics of coal distribution network and the advantages and disadvantages of traditional reactive power compensation device, it is proposed that reactive power generator (SVG) and capacitor bank cooperate to realize reactive power optimization of distribution network Two-stage reactive power optimization method, the two phases are respectively aimed at the minimum of active power loss and the minimum of voltage harmonic distortion, the compensation position is determined according to the sensitivity method, and the optimal particle swarm optimization algorithm is used to optimize the reactive power compensation capacity. : The active power loss of the distribution network is obviously decreased, the voltage level is obviously improved, which provides a flexible, efficient and easy-to-implement effective method for the distribution network reactive power optimization.
