摘要
从换相失败的机理出发，依据银东直流系统实际参数建立其PSCAD电磁暂态仿真模型，对受端山东交流电网等值建模，并对山东青岛地区电网的220KV交流联络线设置单相接地故障，研究分析其对银东直流输电系统换相失败的影响，能够为±660kV银东直流输电工程的稳定运行和故障解决提供指导和理论依据。
The commutation failure is analyzed in the paper. The PSCAD model of the HVDC system is established based on actual parameters. Equivalent model of Shandong power grid is established using a physical equivalent method. Through setting single-phase faults in 220kV AC lines of Qingdao power grid, impacts on Yindong HVDC transmission system are analyzed. The analysis will provide guidance and theoretical basis for stable operation and troubleshooting of the ±660kV Yindong HVDC transmission system.
