摘　　要：在探讨现有电压闪变检测方法的基础上,结合平方检测法和补偿迭代检测法提出了抵消基波分量法,借助LabVIEW平台建立了闪变检测系统并进行了仿真。结果表明,在此平台上采用基于抵消基波分量法建立的闪变检测系统,低频段具有精度高和实时性好的特点,多频调幅信号时更具优越性,更加适合风电场电压闪变的检测。On the basis of research of the current voltage flicker test methods, and with a combination of square method and compensation iteration method, the thesisi puts forward offset base wave component method and establishes flicker detection system and performs simulation by dint of Lab VIEW platform. The result shows that the flicker detection system, established on this platform, adopting offset base wave component method, posseses the characteristics of high accuracy and good real-time performance in low frequency stage. Besides, in multi-frequency amplitude modulated signal, it is more advantageous and more suitable for the detection of wind power voltage flicker.
