In computer, optical-electronic, power electronics and other manufacturing and application technology matures today, this also to become broad scientific workers attention and research hotspot. Photovoltaic power generation is one of them. Although photovoltaic power of practical application of various limitations exist, but as photovoltaic energy cost reduction and mineral energy reduction, someday photovoltaic energy costs will and traditional power costs quite. When high-voltage transmission network, can participate in power transmission and allocate, the future of the countries around the world of the important renewable power generation development direction. In the next ten years, our solar photovoltaic market will to grid (pv) power direction. How to use the safe, efficient and practical solar photovoltaic power grid feeder system, to satisfy the solar photovoltaic power generation system of the public networks actual need, enhance Chinas solar photovoltaic power grid feeder system, becoming a very important issue.
