Harmonics produced by converter and other loads critically influence power quality,because power supply system for offshore oil fields is a weak radial electric grid.In this paper,a 6.3kV typical model for network configuration in oil fields is established in professional software for power system,i.e.ETAP 7.0,which is used to study the harmonic characters and the influences on network bus voltages.Besides,an on-the-spot dispersion solution is presented.The result of the analysis and comparison between harmonics before and after compensation proves that the design is effective.Thus,it can be applied to the initial establishment of network in oil fields.
