【Abstract】 An optimization method for parameter design of a Passive Power Filter based on the Genetic Algorithm is presented. In order to analyze the harmonic current in jected into the power system, a model of passive power device and expressions of the harmonic currents are proposed according to Norton theorem. Practical tests show that, the harmonic currents injected into the power system meet the national criterion GB/T—14549—93 and its power factor is increased to 0.94 from 0.82 by optimization method.更多还原
