Research On Building Integrated Photovoltaie Grid-connected Technology

With the emergence of energy crisis and environmental pollution, clean energy has been developed greatly. Solar energy is a kind of nonpolluting renewable energy which is of great value of large scale development and has a good prospect of application and extension. The building integrated photovoltaic (BIPV) is applied widely because of the shortage of land-source in city. The Photovoltaic generation is one of the efficient ways to utilize solar energy which has attracted a great of attentions and research in recent years. Research on photovoltaic grid-connected generation is such a subject that it has great theory value as well as practical significance. The photovoltaic grid-connected generation system and its main technology are studied in this paper.First of all, a survey is made on the development state and prospect of photovoltaic power generation. Then the project about photovoltaic power generation is introduced as well as the technological characteristic and its final goal.The photovoltaic grid-connected generation system mainly contains photovoltaic module, grid-connected inverter, electrical access system, monitor system, and so on. The schemes are proposed about the photovoltaic system, DC-combiner-box, grid-connected inverter, as well as the protect device, communication system, and the measuring method.Based on the photovoltaic grid-connected generation system, thesis provided the maintain method to keep the BIPV under good operation condition.At last, the environment influence and its popularized value are analyzed, the efficiency of energy conversion and power generation are calculated, and it proposed the potential risk and control method about the BIPV project.
