摘要
介绍了国内外太阳能光伏发电的历史,分析了孤立光伏发电系统和并网光伏发电系统的原理、设备组成。探究了太阳能光伏并网系统的不足,并提出了一些解决办法。与孤立光伏发电系统相比,太阳能光伏并网系统始终以最大功率点发电,与电网连接后可将多余的电输送到电网上,当不满足用电需求时还可直接从电网中获得。
This paper introduced the developments of solar photovohaic generation in China and abroad. The principle and component of isolated photovoltaic generation systems and grid-connected photovohaic generation system were analyzed. Compared with isolated photovohaic generation systems, the grid-connected photovoltaic generation system, with maximum power point tracking, transmits the extra electricity to the grid after it is connected to the grid. The electric energy is directly obtained from the grid when the electricity of grid-connected photovoltaic generation system is lacking.
