| Abstract: | By means of comparing several short-term power quality disturbance detection methods, the superiority of wavelet analysis method is pointed out. Using Lacunaris algorithm the wavelet transform is programmed by programming language C, the correctness of the algorithm and program is verified by Microsoft Visual C++ 6.0 and Matlab simulation, so a realizable condition is provided for the development of power quality detection device which adopts the digital signal processor (DSP) as its operation kernel. Other problems to be solved in the development of short-term power quality detection device by DSP are also pointed out. |
