选择某地区实际电网,建立了典型牵引供电系统和公用电网的PSCAD/EMTDC仿真模型,所谓典型公用电网,是指通过大量的资料搜集和整理,得到的电能质量问题突出,特别是电气化铁路负荷较重,且电网结构比较薄弱的某地区电网.
Select an area the actual power grid, the establishment of a typical utility grid power supply system and the PSCAD / EMTDC simulation model, the so-called typical utility grid, is through a large number of data collection and collation, power quality problems are highlighted, in particular electric railway load heavier, and the relatively weak power grid structure of a regional power grid.
采用上述仿真模型进行仿真,得到变电站母线谐波情况,将仿真结果和实际测试数据进行了对比,仿真结果表明所建立模型可以很好地反映牵引供电系统的谐波情况和负序影响等.验证了所建立仿真模型的可靠性.
The simulation model using simulation, harmonic case of Bus, the simulation results and actual test data were compared with simulation results show that the established model can well reflect the situation of traction power supply system and the negative sequence of harmonic impacts. verify the reliability of the established simulation model.
利用所建立模型详细分析了不同接线牵引变压器对公用电网产生的谐波和负序影响,并从谐波、负序等电能质量污染因素和经济因素综合评价,得到Scott接线和阻抗匹配平衡牵引变的综合性能最好.
Using the established model to analyze the different traction transformer on the utility grid and the negative sequence harmonics generated by the impact and from the harmonics, negative sequence power quality and other pollution factors and economic factors evaluation, by Scott wiring and impedance balanced traction best properties.
仿真分析结果具有较高的可信度和工程参考价值.
Simulation results with high reliability and value of engineering.
随着高压直流输电的发展和各种电力电子装置的大量应用,电力系统的非线性负荷部分越来越不容忽视,使得谐波问题更加突出。对不平衡的三相系统,由于系统自身的不对称或者负荷的不对称使得系统的谐波呈现明显的不对称性。
With the development of high-voltage direct current transmission and a variety of large-scale application of power electronic devices, power system, part of the nonlinear loads more can not be ignored, making the harmonic problems become more prominent. Of unbalanced three-phase system, due to the asymmetric or the system itself makes the system asymmetric load harmonic showed obvious asymmetry.
