| 摘要: |
| 为解决中低压配电网中普遍存在的三相负荷不平衡问题，详细分析了三相不平衡负荷的特性，对三相不平衡负荷的补偿原理进行了深入的研究，给出了三相不平衡负荷补偿的一般原则，并在此基础上，提出了使用TCR＋TSC型SVC作为三相不平衡负荷的补偿装置，从数值仿真结果可知，这种无功补偿装置不仅可平衡三相负荷，而且可将三相负荷的功率因数补偿到1。 |

| Abstract: |
| Asymmetric load is quite common in distribution network and its compensation is a serious problem under some situations.The power capacitor is incapable of balancing asymmetric load although it improves power factor.The characteristics of asymmetric load are analyzed and its compensation concept is detailed.The general principle to compensate asymmetric load is given and SVC (TCR+TSC),a kind of compensator,is proposed based on it to balance the asymmetric load in distribution network.The numerical simulation results show that it can not only balance the three phase load,but also improve the power factor to 1. |
