| Along with MARPOL VI, published by IMO, effective in2005, shipping has been incorporated into the energy saving, environmental protection industries. A new study of the United Nations in2008showed, the CO2emissions of commercial shipping are almost previously estimated nearly3times. According to estimation, annual CO2emissions of global shipping were about1120million tons, about4.5%of global CO2emissions, while IMO had estimated400million tons before. According to the Spanish newspaper Rebelion reported that the emissions of sea pollutants would increase75%than current in2020. As the solar energy does not pollute the environment, it is internationally recognized as an ideal alternative energy sources. Along with the solar photovoltaic power generation technology unceasing development, the efficiency, reliability and stability are greatly improved. Therefore the research of photovoltaic power generation from the initial simple technology is gradually turning to practical applications. The solar photovoltaic application in ships is an important developing direction of the green ship.As the ship used for water transport, the environment of marine solar photovoltaic power generation system is relatively poor. This increases the complexity of solar photovoltaic power generation system reliability. Marine solar power system mainly has two kinds of forms. One kind is called independent, as an independent power supply to parts of ship equipments. Another kind is grid-connected, incorporated into the ship electric power system, electric energy distributed by power grid. Marine solar photovoltaic power generation system whether the independent or grid-connected has the following key problems:layout optimization, the reliability of installation, marine environmental compatibility and adaptability.This thesis firstly studies the marine photovoltaic system arrangement optimization of important and complex problem, namely the solar panel layout optimization problem. It includes considerations for solar cell panel on board layout and analysis of photovoltaic array arrangement on the effects of ship safety. Then it studies on marine photovoltaic system installation reliability problems, including the installation place, component selection and bracket corrosion problems, as well as the solar array support design. Finally we study the marine solar photovoltaic power system electromagnetic compatibility. It is discussed from ships and photovoltaic power generation system two parts.3D electromagnetic simulation software is used to establish the simulation model of photovoltaic PV module. Than antenna parameters is calculated and its effect to ship communication of VHF frequency is discussed. |
