With analyzing the 10kV distributing network structure in Tonglu

the method and strategy of selecting transformer taps reasonably and compensating reactive power automatically in 10kV line were provided in this paper

which improved the voltage quality preferably.Configuring static compensation equipment optimally was a effective method to resolve the problem of fluctuated load disturbed each other resulting in electric machine burning out.Low cost way was used to mitigate the effect of voltage dip or swell and make each motor running stably.
