2kwdt散货船的电力设计 摘要 近些年，随着全球经济的逐日增长以及世界贸易逐步走向一体化道路, 全球的航运市场正在稳步向前，有条不紊的增长，这促进了对货轮的巨大 要求。82000吨散货船由于具备良好的通过能力以及较高的性价比占据着 市场的主导地位。目前船舶制造对船舶的节能和环保正在逐步关注，作为 船舶的重要系统之一的电力系统正是基于此原因进行研究的，并H具有一 定的实际价值。 本文以82000吨散货船的屯力系统为研究对象，结合理论基础和实践 经验，对船舶的屯力系统进行了分析和设计，主要包括了以下内容： 船舶电力系统的分析；利用三类负载法计算船舶电力的负载，通过负 载计算发动机组的容量并进行台数的选择；选择船舶电网的配电方式，并 进行船舶电网一次电力系统图和二次系统图的设计；完成电力系统比较典 型的短路电流计算以及断路器的选型工作；分析断路保护的作用并对 82000吨散货船进行继电保护的设计。 本课题进行了较为完整的82000吨散货船的电力系统的设计，对实际 散货船的设计和选择有着重要的意义。 关键词：82000吨散货船；电力系统；电网设计；短路电流计算；继电保 护 The Design for 82000DWT Bulk Carriar Abstract In recent years, with the global economic growth and the gradual integration of world trade, the global shipping market is moving forward steadily and orderly, it promotes the huge demand for cargo ships.82000 tons of bulk cargo ship can dominate the market because of the good passing ability and higher price to dominate the market. At present^ the energy saving and environmental protection of the ship is gradually concerned. As one of the important systems of the ship, the electric power system is studied based on this reason, and it has certain practical value? This paper takes the power system of 82000 ton bulk cargo ship as the research object, the ship power system is analyzed and designed combined with the theoretical basis and practical experience, mainly including the following: Analysis of ship electric power system;Calculate power load of the ship by using of three kinds of load calculation method, obtain the capacity of the engines and the number of options;Sclcct the distribution mode of the ship power grid, and design the power system diagram and the second system diagram of the ship power system.The typical short-circuit current calculation of the power system and the type selections of the circuit breaker are completed; Analysis of the role of circuit protection and the design of the 82000 tons bulk carrier relay protcction. This topic has carried on the 82000 tons bulk cargo ships electric power system design, and it has th
