【Abstract】 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.更多还原
