摘要:
[目的] 云南富宁±500 kV换流站由于系统要求复杂、进出线回路多、站址地形条件恶劣等限制因素,有必要优化电气总平面布置,以减少占地、节约工程投资。 [方法] 从影响并制约电气总平面布置的系统条件、线路条件、地形条件等外部条件适应性入手,探讨本站电气总平面可利用的区域范围及合理的各配电装置区域布置分布图,根据对站内各配电装置区域典型布置的分析研究,提出各区域典型布置图,并给出了4个电气总平面布置方案。 [结果] 经过技术经济综合比较,推荐了占地少、投资省、建设快、运行便利的总平面布置方案。 [结论] 依据系统条件、出线条件、站址地形条件,并综合考虑建设、投资和运维等因素进行的总平面优化思路能为后续工程提供有益借鉴和参考。
Abstract:
[Introduction] As far as Yunnan Funing converter station (±500 kV), it is necessary to optimize the general electric arrangement to reduce the land occupation and save project investment because of the complicated requirements of the system, the large number of circuits and the rough site terrain and so on. [Method] To start with the adaptability of the external conditions such as the system conditions, line conditions and terrain conditions which affect and restrict the general electric arrangement, the available area coverage of the general electric plane and the reasonable distribution map of the distribution devices were discussed. Afterwards, based on the analysis of the typical distribution of the distribution units in the station, the typical layout of each regions was presented, meanwhile four proposals were concluded. [Result] In the end, it is recommended one proposal which requires less land, less investment, faster construction and more convenient operation after the comprehensive technical and economic comparison. [Conclusion] Based on the system conditions, line conditions, site terrain conditions, and comprehensive consideration of the construction, investment and operation and maintenance, the optimization ideas in this article is able to provide a useful reference for follow-up projects.
