Abstract:

考虑电励磁直驱风力发电系统的运行特点,基于电励磁同步发电机(EESG)电压模型的磁链观测器是较合适的磁链观测方案。本文采用改进型二阶广义积分器(ImprovedSecond-OrderGeneralizedIntegrator,ISOGI)来代替电压模型中的纯积分器,能有效解决纯积分器存在的直流偏置、积分饱和等问题,从而得到的一种新型的基于ISOGI的磁链观测器。采用此磁链观测器可以得到气隙磁链的幅值和相位,从而可实现基于气隙磁链定向的EESG矢量控制系统。仿真和实验结果表明基于ISOGI磁链观测器是可行的,且此方案在风力发电系统要求的频率范围具有较好的稳态及动态性能。
