无功补偿在配电系统中具有重要的作用。在疆南电网10伏及以下配电网中,供电线路上“T”接有几台或十几台甚至二、三十台容量不等的配电变压器。变压器的三相间不平衡电流是客观存在的,每台变压器的用电不平衡状况不具备规律性,每相 Reactive power compensation plays an important role in distribution system. In Xinjiang Power Grid 10 volts and below the distribution network, the power supply line “T ” then there are several or more than a dozen or even two or thirty distribution transformers ranging in capacity. Transformer unbalanced three-phase current is an objective reality, each transformer does not have the regularity of the imbalance in electricity consumption, each phase
