摘要
为了避免对双馈型异步发电机(DFIG)使用定子磁链定向控制而可能带来的系统不稳定现象,同时也为了验证DFIG的定子电压定向(SVO)的控制性能,对DFIG的定子电压定向进行了研究。首先介绍了定子电压定向相对于定子磁链定向的优点,然后根据DFIG的数学模型,推导得出了定子电压定向控制的表达式,并给出了其控制框图。最后在Matlab/Simulink仿真环境中对该控制算法进行了验证,结果表明定子电压控制能很好地对DFIG进行控制,是一种性能优良的控制方法。
In order to avoid instability of DFIG due to stator flux oriented control method,and to verify the stator voltage oriented strategy′s performance,stator voltage oriented strategy was researched.First the advantage of stator voltage oriented control method was introduced.Then the expression formula was developed according to DFIG model.And the control diagram was given.At last a simulation in Matlab/Simulink environment was performed to verify the validation of stator voltage oriented strategy.The result shows that stator voltage oriented can control the DFIG well and is a good control scheme.
