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.
