The wind energy conversion system is a complex dynamic system which contains multi-coupling and multi-time-scales. The commonly used simplified models are unable to uncover all the detailed dynamics. The real-time co-simulation platform based on real-time digital simulator and GH Bladed is built with a controller hardware-in-loop, in which the kinematics equation of generator rotor is used as the interface to decouple the different time scales, and a specific programmable logic controller is used to build the two-way communication. The effect of signal delay between the two simulation platforms is discussed and the stability of the system is analysed. The proposed co-simulation platform is able to show detailed dynamics of the whole turbine as well as the comprehensive effects of the controllers. The correctness and superiorities are verified by number of simulations.
