摘要
Abstract
A typical model of 500kV double circuit transmission on the same tower is established by PSCAD .The waveform of secondary arc current and recovery voltage are simulated through the short-circuit fault set by FAULT module , which provide not only a basis of the reclosing time of switching equipment and the related parameter relay protection value , but also important parameters of the secondary arc produced by electrostatic coupling and electro -magnetic coupling .At the same time , the impacts of reactance compensation ,fault location and soil resistivity on sec-ondary arc current and recovery voltage are analyzed .Article 500kV with double towers of power transmission and transformation project commissioning , start-up and operation has a certain guiding significance .关键词
