摘要
针对煤矿井下谐波检测中存在的问题,设计一种基于冗余第二代小波分解的煤矿井下电网谐波检测的方法与治理方案。以煤矿井下低压电网为基础,利用Matlab仿真软件建立含有奇次谐波和噪声的谐波,分别用多种提升小波分解,找出最适合的提升小波方法,然后用冗余第二代小波变换分析电网谐波。该方法对井下谐波的快速检测更适应矿井电网的需求,且效果好,能确保井下电网的安全生产。
In the view of the problems in the underground harmonic measurement,designs a kind of measurement methods and scheme based on the second generation wavelet for underground low voltage power grid. On the basis of the coal mine low voltage power grid, using Matlab software to build a sign of odd and noise harmonic. Using a variety kinds of lifting wavelet transform to analyze this sign to find the most suitable lifting wavelet transform. Then using redundant second generation wavelet analysis of power grid. The method has significant meaning in rapid detection of harmonic measurement, ensuring the safety production of underground power grid.
