摘要
海洋捕捞产品的逐年减少,以及对海洋渔业资源养护的需求,养殖已经成为人们获取海洋水产品的主要方式。相比近海养殖,深远海养殖凭借多样的优势已经成为各国养殖发展重点,而安全可靠的养殖设施装备成为了深远海养殖发展的关键。通过大型渔业综合服务平台这种深远海养殖的载体,实现海上定居与生产,对我国海域资源的保护和开发,以及海域疆土的长期守护,具有战略意义。根据服务平台的运行要求,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服务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, as well as the conservation needs of marine fisheries resources, aquaculture has become the main way people get ocean fish.Compared with inshore aquaculture, deep sea aquaculture has become prior development in nations with its multifold advantages. Security and reliable facilities and equipment become the key of deep sea aquaculture development. Through the large offshore fishery platform for the deep-sea aquaculture carrier, achieving maritime settlement and production, have strategic significance on the protection of China's marine resources and development, as well as the long-term protection of territorial waters. According to the service requirements of the platform,combined with the characteristics of electric propulsion system, innovative utilize 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.
