英文摘要 | This paper describes a technique to perform analysis, diagnosis, and isolation of failures in power electronics circuit with EMI problems. We propose the use of an evolving Wavelet network technique to solve EMI problems in power systems. This technique simplifies the analytical system solutions and increases the simulation speed. Taking the advantages of global search abilities of the evolutionary programming and the multi-resolution as well as localization natures of the wavelets, the wavelet network thus constructed can, therefore, identify the inherent nonlinear characteristics of the power system with EMI problems. The simulation methodologies presented in the paper are useful for EMI diagnosis and transient fault detection. Testing results show the feasibility and effectiveness for the application. Comparisons between the Wavelet and ANN ' FFT have been made. |
