1.引言“十二五”期间特高压电网作为智能电网建设的骨干网架,在电力系统中将发挥越来越重要的作用,而特高压电网具有覆盖范围广(多为跨区域电网)、传输距离长、输电容量大等特点,但其线路路径位置偏远,设置光中继站维护不便且成本较高,因此采用带有远程泵浦的超长站距光通信技术已成为跨大区电网联网的重要技术基础;经济的飞跃发展,带动了城市群的兴起,在长江三角洲、珠江三角洲、环渤海湾等地都出现相邻间隔不大于350公里
1. INTRODUCTION UHV grid, as the key grid for smart grid construction, will play an increasingly important role in the power system during the 12th Five-Year Plan period. UHV grids have wide coverage (mostly trans-regional grids ), Long transmission distance and large transmission capacity. However, its route location is remote and optical repeater stations are inconvenient to maintain and costly. Therefore, adopting long-distance optical communication technology with long-range pumps has become a cross-regional grid The important technical basis for networking; economic leaps and bounds, led to the rise of urban agglomeration, in the Yangtze River Delta, Pearl River Delta, the Bohai Bay and other places appear adjacent intervals of not more than 350 km
