魁北克电力40年经验简介

2005年是输电技术领域取得重大突破40周年的标志。1965年11月,世界上第一条735kV线路投入运行,将远在加拿大魁北克省东北部莫尼考尔根河上水电站的电力输送到魁北克南部的主要负荷中心。这是由巨大的水力资源和远距离大规模水电开发前景决定的。魁北克电力不仅仅是这项技术的先锋,而且依靠它发展了庞大的输电网络。现在2500万kW电力通过735kV电网传输,是最初预计的5倍。其中,80%的电力输送距离超过1000km。40年的发展突出说明了735kV输电对远距离大容量电力开发的重要作用。

Introduction of Forty Years of Experience at Hydro-Quebec

The year 2005 marks the fortieth anniversary of a major breakthrough in the field of power transmission technologies.in November 1965,a 735-kV line was commissioned for the first time in the world.It transmitted power from a remote hydroelectric plant on the Manicouagan River,in the northeastern part of the province of Quebec,Canada,to major load centers in southern Quebec.This perspective was inspired by the availability of vast hydraulic resources and the prospect of large scale hydroelectric power plants at remote sites.Hydro-Quebec not only pioneered this technology,but has relied on it ever since to develop an extensive anticipated.Of this,80% is traansmitted over a distance of about a thousand kilometers.This growth over four decades highlights the potential of 735 kV power transmission to sustain latge power system development over a long period.
