Firstly this paper analyzes the research situations about evaluating the electric power quality （EPQ）worldwide ,based on safety and reliable of navigation. Secondly,the paper elaborates research methods on the electricpower quality, and proposes the assessment method, improving method and technological means of power quality. Thirdly,establishes the power quality monitoring and evaluating system for the marine electric network, combining the characterwith Integrated Full Electrical Propulsion （IFEP）. The system can be used to research the impact of network deviationduring the ship maneuvering and exceptional operating case and switching the large electric load on. Finally, the paperimproves the electric power quality by means of the power quality assessment and method performance and technology.
