The resonance issue is generated with the motor in the load because the series compensation capacitor is in series in the line. For solving the problem

the design series compensation degree shall not too high

otherwise the compensation effect will be affected. In this paper

a kind of series and parallel mixed capacitor compensation technology which is suitable for 10 kV power distribution line is proposed.Its basic operating principle is studied in detail

the formula of compensation voltage and compensation reactive power is derived and the influence of relative position of series and parallel compensation capacitor on the compensation result is analyzed. The strategy on deterring the parallel and series compensation capacity is proposed and the capacity design strategy is described further by way of compensation design and computer simulation calculation of one circuit real 10 kV line and the correctness of the theoretical analysis is verified.Finally

one real engineering case with the technology is introduced.
