Harmonic analysis and management of offshore modular drilling rig power system

Due to the rapid development of high power electronic components,and variable frequency speed regulation maturely applied in marine petroleum engineering,attention should be paid to harmonic influence in the application of high power electronic device in desigin of marine engineering project.We have accumulated some experience about harmonic,and based on the generation and impact of harmonic of offshore drilling rig system,we compare and analyze the control program of harmonic in the engineering project.
