SPECTRAL ANALYSIS OF THE MAIN CURRENT OF THE PROOF-OF-COMPLIANCE TEST STATION FOR SYNCHRONOUS GENERATORS

Abstract

It is determined the harmonic composition of main supply currents and voltage of the test station for
synchronous generators working with a varying load. The time intervals corresponding to the return energy to the main
supply is set. Spectrum of the studied current and voltage calculated in detail with method of determining power spectral density of signals. It is checked the compliance of harmonic distortion levels of the current and voltage with requirements of the relevant standards.
