深远海养殖平台的电力推进应用研究

Application of Electric Propulsion System to Deep Sea Aquacultural Platform

在海洋捕捞产量逐年减少的情况下,海洋品的供应将主要依赖水产养殖业的发展。我国近岸海域水土资源有限且受水质状况的限制,深远海水域却拥有着优质的水源、适宜的洋流性水温等得天独厚的优势,是发展现代水产养殖业和海洋经济的新空间,也是推进国家海洋战略的重要组成部分。深远海养殖平台是一种集深远海养殖、鱼苗培育、科考研究、渔获物初加工,渔船补给等功能于一身的整体解决方案。根据养殖平台的运行要求,结合电力推进系统的特点,创新性地将电力推进应用在这种大吨位、无动力定位、需跨洋作业的工作母船上。首先分析了电力推进在该养殖平台上应用的优劣势;并根据其实际运行工况,对在其上的电力推进系统配备设计方案;最后通过使用ETAP软件分析验证该方案的潮流、短路电流以及谐波,确定方案的可行性。

While decreasing production of marine fishing year by year, the marine aquatic products will mainly depend on the aquaculture. Chinese coastal water resources are limited and restricted by the poor quality conditions, but deep sea waters have a high quality water with suitable ocean current water temperature and other unique advantages. The deep sea far away from the mainland becomes the new space for modern aquaculture, and also turn into an important part of the country marine strategy. Deep sea aquacultural platform is an overall solution of deep-sea aquaculture, fish breeding, scientific research, preliminary processing of fishery catches, fishing boats supply and other functions. According to the service requirements of the platform, combined with the characteristics of electric propulsion system, the paper innovative utilizes the electric propulsion system on such a large tonnage, no dynamic positioning, transshipment work mother ship. Firstly, the advantages and disadvantages of the application of electric propulsion on the platform are analyzed, according to the actual operating conditions, the scheme of electric propulsion system is designed. Then ETAP is used to verify the power flow, short circuit current, as well as harmonic analysis, to determine the feasibility of the scheme.
