摘要: 电力系统由众多不同类元件构成,不同元件的参数对电力系统暂态稳定性的影响程度不同。以暂态稳定性测度指标为基础,通过电气介数加权,综合分析网络参数对暂态稳定性的影响程度,从而为电网规划和运行提供参考。在PSASP中搭建华中某省500 kV主干网络模型,根据所提出的计及电气介数的暂态稳定性测度指标,对该网络的变压器和输电线路进行测度指标排序,并按照排序结果修改元件的相应参数,通过暂态仿真计算发现,按照测度指标排序对元件参数进行修改能够有效提高电网的暂态稳定性,验证了所提指标的有效性。

Abstract: Power system is composed of many different types of components. Different component parameters have different impacts on power system transient stability. A comprehensive analysis is performed on impacts of grid parameters. The analysis is based on transient stability measure indexes weighted by electrical betweenness. According to proposed transient stability indices, a Central China province 500 kV power grid is modeled and analyzed in PSASP. The transformers and transmission lines are evaluated per ranking of proposed transient stability indices. The simulation results validate the effectiveness of proposed indices.

Key words: network structure, element parameters, electric betweenness, transient stability, transient stability measurement index
