改进型500kVHGIS配电装置横向尺寸优化研究

Study on Lateral Size Optimization of Improved 500 kV HGIS Distribution Device

针对当前应用较为广泛的改进型500kVHGIS配电装置,以某500kV变电站500kVHGIS配电装置设计方案为依托,提出了配电装置横向尺寸优化方案,即根据给定的外部环境条件,分别计算和校验500kV配电装置跨线和跳线的相间、相地距离,压缩常规方案不必要的裕度,达到优化配电装置横向尺寸的目的。优化后,500kV配电装置横向总宽度由可研方案212m优化至183m,横向尺寸减少13.6%,优化效果较为显著。

Aiming at the layout of improved 500 kV HGIS distribution device, based on the design scheme of 500 kV HGIS distribution device in a 500 kV substation, a lateral dimension optimization scheme of distribution device is proposed, which calculates and verifies the phase-to-ground distances of 500 kV distribution device and jumpers respectively according to the given external environment conditions, and compresses the unnecessary margin of conventional scheme. To achieve the purpose of optimizing the lateral size of distribution devices. After optimization, the total transverse width of 500 kV distribution device is optimized from 212 m to 183 m, and the transverse dimension is reduced by 13.6%. The optimization effect is remarkable.
