摘要
在电网中,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和系统不平衡度进行了深入的研究,提出了全电容补偿策略。最后,根据补偿策略提出了一种新的控制算法,并对其进行的验证,表明此补偿策略是有效的。
Three unbalanced phase loads varies randomly to lead to three phases unbalance in low voltage distribution system, which brings a series of problems on power grid. The article deeply studies the compensation principles of three unbalanced phase loads and unbalanced degree, provides the compensation arithmetic of the whole capacitance. The last, the article provides the new control arithmetic basis of the compensation policy. The simulation results and practical operation show that the integrated compensation is ef- fective.
