The Research of Quick Response Magnetically Controlled Reactor in the Wind Farm

针对目前风电场使用的磁控电抗器的反应速度较慢,不能满足风电场快速无功补偿要求的现状,提出了一种快速反应型高压磁控电抗器的技术方案.给出了该磁控电抗器的铁芯与绕组结构以及快速跟踪原理,并对电抗器的稳态工作过程及其稳态运行参数进行了分析,提出了其快速跟踪时间的表达式.仿真结果表明,该快速反应型磁控电抗器具有很快的电流跟踪速度,可以满足风电场快速无功动态补偿装置的跟踪时间要求.

The magnetically controlled reactor in the wind farm had a slow reaction speed,it could not meet the requirements of fast reactive power compensation in the wind farm. In order to solve the problem,a scheme of quick response magnetically controlled reactor which took advantage of improved winding structure as well as the quick response principle was presented. The steady state operation process and steady state parameters were analyzed,and the quick response time expression was given. The simulation results showed that the current tracking speed of the quick response magnetically controlled reactor was quick,it could meet tracking time requirements of the fast reactive power dynamic compensation device in the wind farm.
