The invention relates to a method of inspecting electromagnetic transient characteristics of a double-feed induction wind turbine generation set. The method includes following steps: building a math model of a DFIG wind turbine generation set in an alpha-beta coordinate system, and acquiring an equivalent circuit diagram of the DFIG wind turbine generation set in the alpha-beta coordinate system; analyzing characteristics of the DFIG wind turbine generation set in Crowbar cut-in state and uncut-in state during low-voltage penetration, and making equivalent circuit diagrams of the set during voltage fall according to respective circumstances; analyzing a circulating passage of transient current component of the set when Crowbar is in different cut-in states to acquire a DFIG wind turbine generation set equivalent circuit only relating to transient component current; acquiring electromagnetic transient response characteristics of the set in Crowbar cut-in and uncut-in states according to the DFIG wind turbine generation set equivalent circuit corresponding to the transient current component. By the method, response characteristics of the wind turbine generation set when a power system is in a failed state can be acquired; the method is of great significance in planning, designing and running power systems containing wind power.
