Reactor combination optimization method in submarine cable withstand voltage test

The basic principles of series resonance are analyzed. Combined with the instrument model and the actual parameters of the wind farm submarine cable, a combination optimization method including series resonance and parallel compensation is proposed. The calculation process of this method is summarized, which can effectively reduce the number and power of test equipment. Based on the proposed method, the AC withstand voltage test of 66kV submarine cable is completed by using portable and small capacity test instruments for offshore wind power.
