摘要
介绍了紧凑型线路的技术特点及国内外应用情况,特别对位于南方电网高海拔地区的500 kV罗平—百色紧凑型输电线路主要技术特点、工程造价、运行情况进行了分析。500 kV罗平—百色紧凑型线路工程投运后,云南电网出口断面稳定极限提高了,西电送广东的容量增加了,也进一步提高了南方电网的技术含量,对南方电网的技术升级起到了重要的推动作用。最后指出,从西部高原到南方沿海地区的南方电网系统,因其输电线路走廊用地紧张,赔偿费用高,采用紧凑型输电线路将有广阔的前景。
This paper introduces the technical characteristics of compact transmission lines and their applications at home and abroad, emphatically analyzing the main technical features, project costs and operation of 500 kV compact transmission line from Luoping to Baise located at high altitudes of southern power grid of China. The operation of the 500 kV Luoping - Baise compact transmission line raises the stability limit at Yunnan grid outlet, increases the capacity of west-to-Guangdong power transmission, further improves the technical level of southern power grid, and promotes the technical upgrading of the grid. It is finally indicated that due to the shortage of land for transmission line corridor and the high compensation, the compact transmission technique will have broad prospects in southern power grid that ranges from western altiplano to southern coastal area.
