Wind turbine modelling for transient analysis: Application to the Spanish Grid Code

The aim of this paper is the implementation of a dynamic model of a DFIG variable speed wind turbine where all the parameters are known and that can be used for different types of dynamic studies as, for example, the evaluation of its transient state and steady state response, using different control strategies, when it is submitted to any type of fault, and in this type of events are studied the compliance degree of the imposed requirements by the Spanish Grid Code. Another application of the above DFIG model is that it can also be used as a building block for creating an aggregated model of a wind farm and, thus, studying the behaviour of the whole wind farm under such faults.
