| 摘 要： | 为提高有源滤波器谐波电流检测的跟踪速度和精度,对传统FBD检测方法进行了改进。结合FBD检测方法和瞬时无功理论,实现三相四线制电容分裂式有源电力滤波器上下电容的均压控制;为提高谐波电流的检测精度和动态响应速度,利用滑动窗口均值滤波方法替代原有的低通滤波器,对有源电力滤波器的补偿效果有很大的提高。最后通过仿真分析比较,验证了改进方法有效性和可行性。

| Abstract: | An improved FBD detection method is improved to enhance the harmonic current detection tracking speed and precision of active power filter. In order to achieve the average voltage control of up and low capacitor for split-capacitor-type three-phaze-four-wire active power filter, the instantaneous reactive power theory is combined with the instantaneous reactive power theory . A sliding window average filtering method is used to replace the low pass filter link of traditional method to improve the harmonic current detection accuracy , real-time performance and compensation effect of the active power filter. Finally, the simulation results verifys the effectiveness and feasibility of the improved method by analysizing and comparing . |
