摘要
本文研究一种直驱风力发电在煤矿蓄水系统中的应用,基于背靠背双三电平拓扑结构,分析永磁直驱风力发电系统的运行特性,并给出永磁同步发电机(PMSG)数学模型及其具体的矢量控制策略,分析一种简化的三电平电压空间矢量调制算法。基于MATLAB仿真,验证了系统在风速变化时能够实现追踪最大功率,充分利用风能进行抽水蓄能。
The paper researches the application of direct- driven permanent magnet synchronous wind generator in coal water storage systems, and investigates the operation characteristics of direct - driven wind power system based on three levels of back - to - back topology, give out the mathematic model of permanent magnet synchronous genera- tor and its detailed vector control strategy, and analyzes a simplified three level voltage space vector modulation algo- Based on MATLAB simulation, the paper demonstrates that the system could realize maximum power point tracking with wind speed changes, and make full use of wind energy for pumping water storage.
