摘要
提出一种基于补偿法计及牵引供电系统的故障计算方法。在该算法中只需更改故障模型中的相关阻抗参数即可描述不同牵引变压器牵引侧的各种短路故障。将该算法应用到现有输电网故障计算软件中,并通过PSCAD建立仿真模型进行验证。忽略由计算带来的舍入误差,仿真结果和补偿法计算结果相等,验证了该方法的正确性和有效性。
This paper proposes a compensation method based fault calculation method for traction power system, by which various faults of diltereut traction transformers can be described changing relevant impedance parameters. The method is applied tu existing transmission network fault calculation software and verified with the simulation model established by PSCAD. Ignoring the rounding error in calculation, the results are equal in both simulation and calculation, and show the correctness and eftectiveness of the method.
