粒子群优化模拟电荷法在HGIS工频电场计算中的应用

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建设中得到越来越多的应用。研究分析HGIS工频电场分布规律,对智能变电站设计与建设、电磁环境评估、消除民众对输变电工程电磁辐射不必要的担忧等有着重要的指导和现实意义。鉴于传统模拟电荷法（CSM）在布点和校验上过于繁琐,难以应对复杂计算场景的问题,本文提出将粒子群优化算法（PSO）和传统模拟电荷法结合,形成优化模拟电荷法（PSO-CSM）,并将其应用到500kV HGIS配电装置区工频电场的计算与分析中,计算分析配电装置区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分布状况,并提出了电场优化的相关建议和改进措施。

Power-frequency electric field calculation of HGIS based on particle swarm optimization and charge simulation method

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 and safe and reliable operation. The research of HGIS power frequency electrical field is of great significance for intelligent substation design and squash people''s unnecessary worrying. Traditional Charge Stimulation Method (CSM) is too complicated to deal with the problem of complex computing scenarios, this paper proposes a new method, which combines Particle Swarm Optimization (PSO) with traditional charge stimulation method, to form an optimized Charge Stimulation Method (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 are put forward.
