摘要
在交流电网中,常常采用移相电容器补偿无功功率损耗的方法来提高网络的功率因数。介绍了移相电容器在电网中的补偿方法主要有三种,即随机补偿、随器补偿和低压集中补偿。给出了合理选择移相电容器容量的计算公式,满足电网的安全、经济、合理地运行要求。
In AC power network, the way of phase-shifting capacitors to compensate reactive power loss is always adopted to raise network power factor. Introduction was made to the three compensation ways of phase-shifting capacitors in power network mainly, that were optional compensation, following apparatus compensation and low-voltage centralized compensation. The calculation formula to reasonably select phase-shifting capacitors＇ capacity was given, meeting the requirements for power network in safe, economic and reasonable operation.
