Abstract
In the 20th century, the world's energy structure, the use of human energy is mainly oil, natural gas and coal, and other one-time energy. Along with the economic development, population growth and social improvement of living standards, energy consumption growth, the world's energy crisis has already emerged. Countries all over the world to actively seek a sustainable development of new and clean energy. The highly efficient solar energy as a clean and sustainable development of new energy sources, particularly wide attention. And the use of photovoltaic solar energy will be the main form of solar photovoltaic systems and networks. In this context, this paper, solar photovoltaic systems and network hardware design, main technology , carried out in一depth exploration.
This paper studies in recent years in the full field of photovoltaic generating important research results on the basis of a three-phase design of photovoltaic power generation system and network, the topology of the system design, control circuit design is given a detailed design features. DSPTMS320LF2407 for the control of the core to achieve the current protection, data acquisition, and other functions, and for various photovoltaic network control algorithm provides a flexible and reliable hardware platform. At the same time, this article also introduced solar-powered grid-connected PV system to the maximum power tracking techniques and an island effect of detection and protection technology.
