Method for simulating dynamic load in numerical simulation model

The invention discloses a method for simulating a dynamic load in a numerical simulation model. The method comprises the following contents of selecting a circuit formed by the parallel connection of a variable resistor and an inductor as a primary loop of a dynamic load; simulating the active power and reactive power curves of actual dynamic load, calculating a variable resistance value and an inductance value, and realizing the change of the dynamic load according to an expected curve through controlling the variable resistance and the inductance. According to the method, the accurate, simple and effective dynamic load modeling can be realized.
