Abstract
Though the customers have installed AC filters
background harmonic voltages may also cause the harmonic current on PCC to exceed the criterion value.The reasons of over-criterion harmonic current are analyzed by testing results of typical project cases
the mechanism of over-criterion harmonic is explained according to harmonic flow analysis
some relevant measure are put forwards to solve the problem.The feasibility and the validity of analysis method is testified by both practice results and theoretic analysis
analysis model may analysis and resolve related issues in engineering.
