摘要

巴西从1989年开始在Furnas 765 kV交流输电中采用串联补偿,以保障大量水电的稳定输电。今天,总共有9个系列电容器在运行,其中8个由ABB提供,6个在Ivaipora, 2个在Itabera,变电站位于距离电缆两端约三分之一的地方。评级在1017 MVAr (Ivaipora)和1242 MVAr (Itabera)之间变化。当引入时,串联电容器是世界上第一个安装在765千伏的电容器。本文对串联电容器组进行了描述,并对串联电容器组的运行性能进行了评价

Operational experience of 800 kV series capacitors
In Brazil, series compensation has been used since 1989 in the Furnas 765 kV AC power transmission to safeguard stable transmission of large amounts of hydro power. Today, a total of nine series capacitors are in operation, eight of which were supplied by ABB, six at Ivaipora and two at Itabera, the substations located about one third from each end of the tie. Ratings vary between 1017 MVAr (Ivaipora) and 1242 MVAr (Itabera). When introduced, the series capacitors were the first in the world to be installed at 765 kV. The paper gives a description of the series capacitor banks and comment on the operational performance of the banks
