摘要
风电机组宽泛的使用环境,使作为机组关键设备之一的大容量变流器必须满足高功率密度、高可靠性与优良控制性能等要求。国产风电变流器的研发近几年有了较快的发展,但总体上依然落后于国外先进水平。文章对风电变流器,重点是直驱式全功率变流器的若干关键技术做了介绍,给出了相关问题的解决思路。
The power converter, which is one of the critical equipments of the system, must meet the requirements of high power density, high reliability and excellent control performance. Great development has been achieved in China about wind power converters, which is still lagging behind the advanced level of the world. In this paper, some critical technologies of direct driven wind power converter systems are introduced and the related design ideas are proposed.
