摘　　要：近年来,复合型气体绝缘组合开关设备(HGIS)以其造价适中、占地面积小、运行安全可靠等优点,在我国超高压变电站的建设中得到越来越多的应用。研究分析HGIS配电装置区的工频电场分布规律,对智能变电站的设计与建设、电磁环境评估以及消除民众对电磁辐射问题的不必要担忧等方面具有重要意义。鉴于传统模拟电荷法(CSM)布点和校验环节过于繁琐,难以应对复杂场景。提出将粒子群优化算法(PSO)和传统模拟电荷法结合,形成粒子群优化模拟电荷法(PSO-CSM)。并将其应用到500 kV HGIS配电装置区工频电场的计算中,研究分析配电装置区内各主要设备对工频电场的影响以及整个配电装置区工频电场的分布状况,并提出变电站工频电场防护的相关建议和改进措施。In recent years,hybrid gas insulated switchgear(HGIS)has been used quite frequently in the construction of UHV substations in China due to its advantages of moderate cost,small area,safe and reliable operation.The research of distribution of HGIS power frequency electrical field is of great significance for the design and construction of smart substation,the electromagnetic environment assessment and the elimination of unnecessary worries of people about electromagnetic radiation.Traditional charge simulation method(CSM)is too complicated to deal with the problem of complex computing scenarios,this paper proposes a novel method,which combines particle swarm optimization(PSO)with traditional charge simulation method(CSM),to form an optimized PSO-CSM,and applies it to the calculation of power frequency electric field in 500 kV HGIS area.During this process,the influence of main equipment on power frequency electric field and the distribution of power frequency electric field in the whole area are calculated and analyzed,and the relevant suggestions and improvement measures for the protection of power frequency electric field in substation are put forward.
