In order to predict the grid harmonic,and providing theoretical basis for improving power supply quality. According to the characteristics of the harmonic wave in the power grid, this paper establishes the BP neural network algorithm,and has carried on the training error to sample points of the harmonic wave in the power grid,harmonic amplitude variation characteristics are obtained finally. By comparison with the standard values,the BP neural network algorithm for harmonic fitting can reach high accuracy.
