Design And Achieve Of Marine Power Station Automation System In Luxury Cruise

As one of the most important equipments of modern ships, as an important part of marine power station automation system, marine power station is the core of the ship power system. Marine power station produces a continuous supplement of the power required by the ship auxiliary machinery and equipment, it is composed of the original motivation, generators and ancillary equipment (combined into a generator) and power distribution equipment. During the operation of marine, the continuity, reliability and endurance capacity of power supply will directly affect the economic indicators, specifications and lifespan of a ship, and has important relationship to the safe navigation and the economic benefits. The quality of marine power station will directly influence the performance of ship.Marine power station automation is one of the important parts of the engine room automation, and at the same time marks the milestone of the ship modernization. It is mainly served to ensure continuity, reliability and quality of the power supply to ship. In order to achieve the automation of the marine power station, two requirements is needed: first is the unit automation, including the achieve of the start of marine generating set, parallel operation, frequency adjustment, the distribution and transfer of load, splitting and stop, and the automation of various protection functions; then the other is based on the automatic function in all cells to make the general plan. The function of each unit automatically likes together according to the given logic to form an organic whole.The main task of this paper is the designing of marine power station automation system of luxury cruise, and is a summery on the basis of the design projects of DCS-457 marine power Station automation system in luxury cruise undertaken by the Chongqing Dong Feng Shipping Design Institute.This paper elaborates the design process of marine power station in a detail way. Firstly, it gives a brief analysis of the marine power Station system. It also offers the preliminary design of ship power station according to the practical requirements and the Ship owner. Then, it calculates marine capacity and short-circuits current of marine power Station, and works out the capacity of marine power station. Secondly, with fully consideration of economy and practicality, it selects the products using in the marine power station. After choosing the products, it designs the control sections of marine power station automation system, include synchronization, frequency modulation, reverse power protection, etc.In the conclusion part, the surveyor gives it a test in accordance with the inland vessels regulatory requirements to marine power. After the simulation runs of ship power plant operation and the collection of operating data, and acceptation of reliability and safety of the marine power Station. After a trial run, as all of the data fully meet the specifications and shipping vessel is successfully delivered. The designing of marine power station automation system in a luxury cruise is finally completed.
