摘要: 高海拔、低气温均会对1 000 kV变电站设备选择和布置方案产生较大影响。目前尚没有在上述环境条件下的特高压变电站设计、建设经验以及相关的技术储备。通过调研设备制造水平及工程运行情况,结合实际需求,对不同的技术方案进行比较后,提出了–45℃、海拔3 500 m以下1 000 kV设备的外绝缘修正建议方法、1 000 kV设备套管建议型式、GIS伴热带设置原则;通过技术经济比较,提出了推荐的设备布置方案。其结论可供后续1 000 kV变电站建设参考。

Abstract: High altitude and low temperature will have a significant impact on type selection and layout of 1 000 kV substation equipment. At present, there are no design and construction experiences as well as related technical reserves for UHV substations under such ambient conditions. Based on an investigation of the current equipment manufacturing level and the operation conditions of existing projects in such environment, and after a comparison of different technical schemes, the paper proposes the external insulation correction method for 1 000 kV equipment, the type of 1 000 kV equipment bushing and the installing principle of heating belt for GIS under the ambient temperature of –45℃ and below the altitude of 3 500 m. The recommended equipment layout scheme is presented through technical and economic comparison. The research results can provide a reference for construction of the follow-up 1 000 kV substations.
