可控电抗器在特高压输电系统中的应用

Application of controlled reactor in ultra-high voltage transmission system

分析了我国发展特高压输电的必要性,介绍了可控电抗器在特高压输电系统中的优异性能。可控电抗器能够随着传输功率的变化而自动平滑地调节本身的容量,因而能显著改善电网的无功补偿、减少电网损耗和提高输电质量。论文还介绍了两种最具应用前景的特高压可控电抗器的结构与功能。

The paper analyzes the necessity of developing ultra-high voltage （UHV） transmission system in China and introduces the excellent performance of controlled reactor in UHV transmission system. According to the change of transmitted power,controlled reactor can automatically and smoothly adjust its capacity. Therefor e,it can conspiciously improve the reactive compensation,minimize the losses and raise transmission quality in electdc networks. The structure and function of two type of UHV controlled reactor with the most development prospect are introduced in the paper.
