应用矢量正交分解法计算背靠背换流站中氧化锌非线性电阻片有功电流的方法

摘要

阐述了S.Fryze功率理论,将金属氧化物避雷器泄漏电流分解为相互正交的有功分量与无功分量,研究了半波、全波、换流阀侧、换流桥侧、换流器侧等5种典型电压作用下金属氧化物避雷器有功电流的计算方法。%Based on the S. Fryze power theory, metal oxide varistor（MOV） leakage current is decomposed into mutu- ally orthogonal active and reactive components. Then algorithms for MOV active current were studied under five typi- cal voltages, namely, half wave, full wave, converter valve side, converter bridge side, and converter side.
