【Abstract】 Since the application of different filters is the main means of harmonic suppression,the development of practical filter design software is necessary.Fundamental functions and characteristics of a developed harmonic filter and reactive power compensation software are introduced.The basic engineering design data,filter configuration and filter parameters are saved in engineering documents;four filter configurations can be arbitrarily combined in a data sheet;rated parameters of filter capacitors are simulated and determined;and the filtering efficiency and parameter can be verified at rated frequency with and without deviation.Parameter input and modification are easy.The user harmonic voltage and current violation and capacitor harmonic magnification,the filter efficiency verification and the filter impedance-frequency characteristics can be conveniently analyzed.The application in a steel mill shows its reliability,stability and convenience.更多还原
