Three-phase grid-connected PV system
Abstract
Solar energy and sustainable development has two major advantages of green, using solar energy resources has been gradually generating national attention, our research in this area in recent years put a lot of manpower and material resources. Of these, the most grid-connected PV practical value and theoretical significance, three-phase grid-connected photovoltaic system photovoltaic gradually e a hot topic applications.
At the same time, photoelectric curtain wall technology and its proper construction the form of bination of electricity in the city has played a significant role. In this context, this paper based on the photoelectric curtain wall for the three-phase grid-connected PV system for analysis and research.
This article first introduced the development of photovoltaic power generation system and the status quo, and the principle of photovoltaic arrays, characteristics and maximum power point tracking technology are described pared monly used maximum power point tracking method. Second of three-phase grid-connected photovoltaic inverter system, part of a detailed analysis, including the photovoltaic inverter and the PWM pulse width modulation technology. At the same time, curtain wall technology for photovoltaic system analysis. Finally, based on the photoelectric curtain wall for the three-phase grid-connected PV system design of the hardware.
Keywords: photovoltaic, photovoltaic curtain wall, inverter,
