摘　　要：随着化石能源的减少,环境污染日益严重,可再生能源的开发和利用已成为国民生活和可持续发展的前提,太阳能作为一切能源的源泉,便成了开发的重点。而太阳能光伏发电是太阳能利用的重要方面。近年来,光伏电池的并网容量日益上升,其与电网之间的相互影响也日益突出。重点研究了电网故障情况下光伏发电系统的低电压穿越(Low Voltage Ride Through,LVRT)控制方法。并在PSCAD/EMTDC上搭建光伏发电系统并网模型,通过仿真验证了该控制方法的正确性。With the reduction of fossil fuels, the increasingly serious environmental pollution, the development and utilization of renewable energy has become the premise of national life and sustainable development, solar energy as a source of all energy, has become the focus of development. And solar photovohaic power generation is an important aspect of the use of solar energy. Nowadays, photovohaic grid-connected capacity increasing, influence between it and the grid is becoming more and more prominent. In view of the grid fault condition, this paper focuses on the Low Voltage Ride Through （LVRT） of photovoltaic system control method. And build the grid-connected photovohaic system in the PSCADVEMTDC model, and the correctness of control method is verified by simulation.
