无功过补偿和欠补偿都会造成损耗的增加.如何较合理地把无功电流限制到最低限度呢?我们认为:在集中补偿与分散补偿相结合的同时,应侧重于分散补偿和随器补偿,这样,才能达到最佳补偿效果.1 随器补偿和分散补偿比集中补偿优越1.1 变电站集中补偿:能补偿主变压器的无功功率损耗及变电站进线侧输入电线路的无功功率损耗,但不能降低配电网络的电能损耗.由于网络负荷的变化,功率因数也随之变化,过补偿和电压升高现象会时有发生.
Reactive compensation and undercompensation will cause the loss increase.How can we reasonably limit the reactive current to a minimum? In our opinion, the combination of centralized compensation and distributed compensation should be focused on the distributed compensation and the follow-up compensation , So as to achieve the best compensation effect.1 The compensation of the slave and dispersion compensation is superior to the centralized compensation 1.1 The centralized compensation of the substation can compensate the reactive power loss of the main transformer and the reactive power loss of the input power line on the line side of the substation Can not reduce the power loss of the distribution network.As the load of the network changes, the power factor also changes, overcompensation and voltage increase will happen from time to time.
