The invention provides a typical fault working condition set-based low-voltage ride through capability simulation and evaluation method. The method comprises the following steps of: (1) establishing awind turbine generator simulation model on the basis of a practical structure and a control strategy of a wind turbine generator; (2) acquiring all the production-class electric equipment data in a wind farm, and establishing a wind farm electric simulation model; (3) establishing a power grid equivalent model by adoption of a voltage source and equivalent impedance combined manner; and (4) evaluating the low-voltage ride through capability of the wind farm according to selected fault working conditions. According to the method, a practical, simple and convenient method is provided for the low-voltage ride through capability check of wind farms, and evaluation and supervision can be carried out on grid connection guide rule requirement conformity of wind farms which are operated and are about to undergo grid connection.
