三相不平衡与无功功率综合补偿系统的研究

The Study of Integrated Compensation System for Three Phases Unbalance and Reactive Power

在中低压配电网中 ,三相负荷随机变化 ,产生三相不平衡 ,从而给电网带来了一系列的问题。本文针对三相不平衡负荷的补偿原理进行了深入的研究 ,提出了补偿算法 ,并且设计了无功功率和三相不平衡补偿的综合系统。仿真结果和实际运行表明 ,此方法是有效的。

Three unbalanced phase loads varies randomly t o lead to three phases unbalance in middle and low voltage distribution system,whi ch brings a series of problems on power grid. The article deeply studies the co mpensation principles of three unbalanced phase loads,provides the compensation arithmetic, and designs the integrated compensation system for three phases unba lance and reactive power. The simulation results and practical operation show t hat the integrated compensation is effective.
