摘　　要：Compared with the traditional energy thermal power, there are still many unstable factors affecting the safe operation of the new green energy wind power in the period of continuous improvement of policy, technology and investment scale. The wind turbine does not have the ability of low-voltage ride through, leading to more than one large-area wind turbine off grid accident in the wind power base, resulting in hundreds of billions of losses. It is imperative to study the low pressure ride through of doubly fed fan. This paper analyzes the process of low-voltage ride through physical model and physical relationship and establishes a simulation model combined with the relevant parameters of a wind farm. It is verified that the low-voltage ride through of the wind farm can meet the requirements of low-voltage ride through operation when the power system fails and the grid fault will not lead to large-scale wind farm off grid.
