According to theharmonic characters in power system, a mathematic model isdone based on it. The simulation results in Matlab indicate thatthe new algorithm is validated in transient signal detection %K Wavelet energy entropy %K transient signal %K power harmonic %K matlab simulation %U http://www.ijapm.org/papers/168-ST0006.pdf
