Abstract: With the continuous expansion of the scale of the grid, more and more new electrical equipment and precision equipment access to electricity power system, and they have inject a large amount of harmonic power grid, the problem is very prominent. Since the system harmonic source numerous and dispersed, this make accurate measurement become a difficult problem, and in order to make a fair price in electricity charges, This is closely related to the harmonic source identification. In order to solve this problem, This paper proposes the method based on harmonic source identification, and through calculation and analysis of the fundamental and harmonic by separation. Analyzing the harmonic power flow in measurement point, and it can provide a basis for reasonable electricity charges in measure harmonics bilateral energy. This paper has create a digital simulation to show its correctness and feasibility.
