Modeling method for electromechanical transient model of doubly-fed wind power generator set

The invention provides a modeling method for an electromechanical transient model of a doubly-fed wind power generator set. From a practical physical device, through a reasonable hypothesis, the electromechanical transient model of the doubly-fed wind power generator set is simplified, and meanwhile, the dynamic process and low-voltage passing characteristics of direct current voltage of a frequency changer are considered. Simulation results show that a simulation curve of the model is consistent to the low-voltage passing actually measured curve of the doubly-fed wind power generator set, the results are accurate and reliable, and the modeling method is used for analyzing the influence of wind power field connection of the large-scale doubly-fed wind power generator set on the transient stability of an electric power system.
