摘要
建立牵引变压器及电源的谐波和负序模型,利用MATLAB编制仿真程序。基于牵引变电所的实测数据进行仿真计算,分析三相电源侧的电能质量指标,即谐波电压畸变率,各次谐波含有率,电压不平衡度,并与实测数据分析结果进行比较,验证仿真模型的正确性。
Firstly,the MATLAB simulation model of traction transformer and power system for harmonic and negative sequence was established. Then simulation calculation was carried out based on the measured data of traction substation,and the power qualities of three-phase power system including voltage distortion rate,harmonic voltage ratio and three phase voltage unbalance were analyzed and compared with the analysis results of measured data to test the correctness of simulation model.
