The invention discloses a simulation method of a doubly-fed induction wind power generation system. The method comprises the following steps: electrical equipment in the doubly-fed induction wind power generation system is modeled according to actual parameters of the doubly-fed induction wind power generation system; based on power grid voltage directional vector control of a doubly-fed motor, anoperation module is adopted to construct a control system of the doubly-fed induction wind power generation system; the electrical equipment and the control system are connected by using a three-phase bridge converter to form a simulation system of the doubly-fed induction wind power generation system; and an input signal is simulated and the electrical quantity of the simulation system is measured through a function generator.
