本文件提供了从概念设计到详细设计前设计基线建立的整个船舶级电力系统的系统工程、设计和集成建议。本文件制定了船上交流电源系统、直流电源系统、应急电源系统、岸电、服务质量（QoS）、电能质量和谐波、电力推进和操纵系统、电机和驱动器、推进器和转向系统的建议。这些建议反映了当今的技术、工程方法和工程实践。本文件拟与IEEE 45（TM）系列文件一起使用。

This document provides recommendations for systems engineering, design, and integration of electrical power systems at the total ship level from concept design through the establishment of the design baseline prior to detail design. Recommendations for ac power systems, dc power systems, emergency power systems, shore power, quality of service (QoS), power quality and harmonics, electric propulsion and maneuvering systems, motors and drives, thrusters, and steering systems onboard ships are established by this document. These recommendations reflect present-day technologies, engineering methods, and engineering practices. This document is intended to be used in conjunction with the IEEE 45(TM) series of documents.
