【Abstract】 The direct axis reactance parameter is a key parameter that affects the dynamic reactive power output capability of the new generation of large synchronous condenser of the State Grid Corporation of China,especially transient reactance x’_d and super-transient reactance x"_d. Combining with two-dimensional finite element simulation analysis,this paper applies the superconducting loop method to the calculation of dynamic reactance parameters of phase modifier. And the paper also compares the results with real machine test results to verify the applicability and accuracy of the proposed method.更多还原
