| The current depleted and environmental pollution, energy the increasingly serious make renewable energy and all kinds of green energy get more and more recognition, has become a human realize sustainable development grants. In recent years, along with the power electronic technology and solar battery technology, the ever-improving solar photovoltaic power generation technology level obtained fast development and the enhancement, is the most promising technology, and also the power of new energy development and utilization of solar energy and one of the most important ways. Currently, photovoltaic energy technology is headed in high efficiency, high power density, high reliability, intelligent direction, and the solar energy application in power for the main way namely 5-month-construction system.General solar photovoltaic power generation system by panels, basic inverter, controller and battery (group) four parts. This research firstly the composition of solar photovoltaic power generation system makes a simple analysis, then introduces the solar photovoltaic power generation technology in domestic application status and development of the classification of a simple division; And from the development cost, efficiency and reliability of solar pv three Angle, to promote the efficiency of grid generation technology pertinency study, and its whole structure system design; Finally, the photovoltaic (pv) grid power system, the inverter has been optimized, and on one of them to typical representative inverter structure, through comparative study summarized design presents a preamp voltage matching, level of the whole bridge after the double Boost inverter topological main circuit structure. Finally, through the Tianjin area of solar power system efficiency analysis, verify this topic design and build solar power system of power efficiency. Operational data show that the institute design and optimization, effectively improves solar photovoltaic (pv) grid power system efficiency. |
