Teager-Kaiser能量算子Blackman-Harris窗三谱线插值的电压闪变参数检测
|
摘要
针对电压闪变的检测,提出了一种基于Teager-Kaiser能量算子和Blackman-Harris窗三谱线插值的闪变参数测量方法。采用能量算子检测出电压波动信号,分析Blackman-Harris窗的旁瓣特性,将闪变包络进行Blackman-Harris窗三谱线插值FFT谱分析与校正,对IEC标准推荐的检波方法进行简化,实现闪变参数的检测分析。通过大量仿真实验证明,在含有单一频率调制、多频率调制、电网基波频率发生偏移、含有谐波、间谐波和白噪声干扰时,文中的检测算法性能优良,相比传统检测方法,算法简单稳定、抗干扰性强,可实现电压闪变参数的在线检测。
For the detection of voltage flicker,a method for the detection of flicker parameters based on Teager-Kaiser energy operator and Blackman-Harris window triple spectrum line interpolation,is proposed in this paper. The voltage fluctuation signals are rapidly extracted by Teager-Kaiser operator,and the side lobe characteristics of Blackman-Harris window are analyzed. In order to realize the detection and analysis of voltage flicker parameters,voltage flicker measurement process based on the IEC standard is simplified,and the envelope based on Blackman-Harris window and triple spectrum line interpolation FFT is analyzed and corrected. A large number of simulation experiments show that the influences of a single frequency of modulating,multi-frequency of modulating waveform,the fluctuations of fundamental grid frequency,harmonics and inter-harmonics influences and white noise interference,are all overcome by this approach. Compared with some conventional methods,the detection algorithm of this paper has a good performance. This algorithm is simple,stable and strong anti-interference,which can realize the on-line detection of voltage flicker parameters.
