粒子群优化模拟电荷法在HGIS工频电场计算中的应用
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.
