Finite Element Method for Direct Axis Reactance Parameters Calculation of Superconducting Circuit-Based Synchronous Condenser

直轴电抗参数是影响国家电网有限公司新一代大型调相机动态无功输出能力的关键参数,尤其是瞬变电抗x’d及超瞬变电抗x"d,结合二维有限元仿真分析,将超导回路法应用于调相机动态电抗参数计算中,并与真机试验结果进行对比验证,以证明本方法的适用性及准确性。

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.
