Basic Research On Thermoelectric-solar-battery Generation Technology In Ship Lighting

Nowadays, traditional fossil fuels the energy mix proportion of is still heavy, and vigorously promote the development of clean energy in improving the use of traditional fossil energy efficiency, energy conservation is an important means. Ships in the transportation industry plays an important role, at present, more than two-thirds of the global volume of international trade depend on the shipping industry, therefore, improve fuel efficiency, the introduction of clean energy is an important research direction of the ship.Heat thermoelectric power generation technology in the ship is still in the exploratory stage,photovoltaic technology through research and development in recent years. In this paper, these two aspects of the heat storage technology as auxiliary power light, do basic research related to lighting systems for ships.First, from the ship starting the actual work environment, according to the operating characteristics of the temperature difference between heat and photovoltaic power generation, the selected target ship. In particular, taking into account the different conditions of the ship,thermoelectric power generation components arranged in the exhaust pipe of Marine Diesel Generator. PV modules are arranged from the deck area and safety performance on two considerations, target ship for bulk carriers.Secondly, through mathematical modeling and simulation to calculate the temperature distribution of the exhaust pipe, on the basis of the calculation using MATLAB exhaust pipe pieces in different locations generating capacity thermoelectric power generation. PV modules use SIMULINK simulation output characteristics under various conditions, using the commonly used P&O and INC methods,PV maximum power point tracking, detailed study of PV module output characteristics.Finally, PSO intelligent algorithms to ship lighting system for the load, relying on shipping routes and actual electricity demand, considering the reliability and economy of thermal power generation components, photovoltaic modules, the number of batteries optimized to meet system reliability At the same time, so that the lowest operating costs.The traditional lighting to LED energy-saving lamps to replace, recalculate the number of components and the effect of replacing the front and rear of the environmental and economic perspectives.
