ABSTRACT:
In a generator starting apparatus, in which commercial frequency electric power supplied from an electric power system is converted into variable-voltage variable-frequency electric power to thereby start a gas turbine generator, a harmonic-component removing apparatus is provided which removes harmonic components contained in the converted variable-voltage variable-frequency electric power on the basis of the detected harmonic components. In addition, an apparatus for removing harmonic components generated in an electric power equipment is provided, wherein harmonic components contained in an electric power system are detected so that they may be removed.
