摘要
本文提出用瞬时统计法确定大气参数以计算海拔修正系数。文章认为,选择高海拔500kV配电装置最小电气距离应根据500kV变电站特点、已有高海拔地区变电站的运行经验及合理确定变电站的绝缘配合等三个方面综合考虑。结合高海拔(2000m)500kV草铺变电站的具体情况,文中提出了最小电气距离的推荐值。
Up to now there is not enough experience on the selection of 500kV substation minimum air clearance in high altitude area. This paper presents a composite method of selecting 500kV substation minimum air clearance in high altitude area. The method considered altitude correction coefficient, substation operation experience in high altitude area and rational substation insulation level. Altitude correction coefficient is determined by instantaneous meteorological probability method.
