摘要
针对风速随机性引起的机组并网有功功率波动问题,提出在采用最大风能捕获策略的永磁直驱风电机组交-直-交变流器的直流侧接入飞轮储能系统,利用飞轮系统的能量缓存作用,以实现永磁直驱风电机组的输出有功功率平滑控制。设计了飞轮储能系统的能量控制策略,并对采用了飞轮储能系统的永磁直驱风电机组的运行特性进行了仿真研究,经仿真验证:采用所提出的飞轮储能系统能量控制策略能够有效平滑风电机组输出有功功率,提高了风电机组的输出电能质量。
Considering the active power fluctuation of wind turbine grid caused by random wind speed, having AC-DC-AC converter＇s DC side equipped with flywheel energy storage system was proposed to implement active power smoothing control through the flywheel energy eaehe; and the control strategy for flywheel energy storage system was designed. Simulating the running characteristies of permanent magnet direct-driven wind turbine shows that the proposed energy control strategy can effectively smooth the exported active power of wind turbine and the power quality can be improved.
