And some indexes of power quality: voltage deviation, real power, reactive power, harmonic content, voltage fluctuation and unbalancedthree-phasevoltage and current, are discussed at length.
This paper presents a new converter control algorithm for the direct drive permanent magnet wind generator under the unbalancedthree-phase source voltage.
提出了一种用于电网侧三相电压不平衡情况下的永磁直驱式风力发电机的逆变控制算法。
