| 摘 要： | 我国超/特高压输电正在蓬勃的发展,但仍面临这很多重大的技术难题,其中很多问题的根源就是超/特高压交流线路的充电功率大,需要无功补偿。目前的超/特高压无功补偿方法都有着自身的缺陷,无法满足要求。本文将12脉波法引入常见的TCR无功补偿技术中,通过MATLAB建模验证了其具有动态无功补偿效果好、响应速度快和谐波小的优点,为超/特高压输电线路的无功补偿提供了一个更好的解决办法。

| Abstract: | Extra and ultra high voltage AC transmission are developing vigorously in China,but which still face many of the major technical problems. The root of those problem is extra and ultra high voltage AC transmission line have great charging power,so the transmission line need reactive compensation.The current extra and ultra high voltage reactive compensation methods have their own defects, and which cannot meet the requirements. In this paper, 12 pulse wave method was introduced into the common TCR reactive compensation technology,then through MATLAB bulid the simulation model and verified the 12 pulse wave TCR have advantages of good dynamic reactive compensation effect, fast response and small harmonic.So the 12 pulse wave TCR provides a better way to solve the problem on the reactive compensation of extra and ultra voltage high AC transmission line. |
