渔船变频供电关键技术及其应用

摘要

This thesis mainly introduces the frequency conversion power supply technology for fishing ships developed by Huanghai Shipbuilding Co. , Ltd. With regard to the present situation of traditional fishing ships' power system, and research and application of frequency conversion power supply technology for fishing ships as well as discussion of its energy saving working principle. This technology adopts the design of electromechanical integration by using hydraulic speed increasing gearbox, main engine and shaft generator, and creates a whole new redevelopment of traditional fishing ships' power system with additional mature frequency conversion technology for the purpose of energy saving and emission reduction. It' s proved after actual test and application on board of ship that the performance of propulsion and power system is steady and there is an obvious effect of fuel saving, and each technical indicator has fulfilled the design requirements. It' s recommended being applied extensively.%针对传统渔船电力系统的现状,重点介绍了渔船变频供电技术,同时对渔船变频供电技术的研究、应用及其节能工作原理进行探讨.通过机电一体化设计,采用液压增速齿轮箱、主机轴带发电机,引入变频技术,对渔船供电系统进行全新的设计,达到节能减排的目的.经实船应用测试,推进和供电系统性能稳定,节油效果明显,各项技术指标均达到了设计要求.
