A method for harmonic power flow in power system, which analyzes networks with discrete wavelet transform and then builds nodal voltage equilibrium equation for system simulation, is presented in this paper. It avoids the requirement of initial state values of components with different border extension styles for the variation of power signals in wavelet transform. Combining with time-frequency analysis method that based on wavelet transform, the method can adjust parameters of filter bank of power supply system for are furnace effectively.
