摘要: 为解决超大规模规划电网暂态安全风险评估时考虑的场景和多重故障不全面的问题,提出一种多重暂态安全预想故障筛选方法,并开发能应用于实际电网的软件。首先,文章建立基于改进K-means聚类的关键场景生成指标和算法;其次,从系统降维的角度提出多重故障筛选思路,建立考虑功角稳定破坏风险、电压稳定破坏风险的多重故障筛选指标和算法;最后,基于PSD-BPA潮流程序,开发超大规模电力系统故障集合平台。以实际规划电网为例验证所提方法的有效性。

Abstract: In order to solve the problem that scenarios and multiple failures considered are not sufficient in transient-security risk assessment of super large scale power grid, a multiple transient security preconceived fault screening method is proposed, and software that can be applied to the actual power grid is developed. First, index and algorithm of key scenarios based on improved K-means cluster are established. Secondly, the idea of multiple faults screening combined with dimension reduction is proposed. The multiple faults screening indexes and algorithms  considering the risk of power angle stability and voltage stability are established. Finally, large-scale power system fault collection platform based on PSD-BPA power flow program is developed. The effectiveness of the proposed evaluation method is validated by the simulation results of actual power grid.

Key words: super large-scale, multiple faults, key scenarios, power angle stability, voltage stability
