Abstract:

提高双馈式风力发电机(doubly-fedinductiongenerator,DFIG)机电暂态模型精度的关键在于对各种类型故障的模拟,如何在对称故障机端电压跌落中等幅度或不对称故障机端电压跌落较深等工况下,建立准确的撬棒电阻(crowbar)保护模型是DFIG机电暂态模型故障模拟的难点。提出一种提高DFIG机电暂态模型crowbar保护仿真精度的方法。首先,建立DFIG感应电机5阶数学模型,以保留转子电流基频分量作为故障下crowbar保护的动作依据;其次,基于动态相量法,提出5阶感应电机模型与机电暂态电力网络的接口算法;最后,在crowbar控制器机电暂态模型中引入转子负序电流补偿,以模拟严重不对称故障下crowbar保护持续投入,恶化系统电压的情况。以华锐1.5MWDFIG机组为例,分析了两种工况下的运行特性,仿真结果与实测曲线一致,表明所提方法可准确模拟crowbar保护的动作过程,提高了DFIG机电暂态模型仿真的精度。
