Large-scale wind farm integration poses serious challenges to the operation and control of power systems. Real-time simulator is an effective tool to reproduce the dynamics within wind farms and the influence on the system. In this paper, a novel design of real-time simulator for permanent magnet synchronous generator (PMSG) based wind farms is proposed using pipeline technique, which can realize the high-efficiency simulation under limited hardware resources compared with traditional method. With the proposed design, a PMSG based wind farm is simulated, and the simulation results are compared with PSCAD/EMTDC to validate the correctness and effectiveness of the design.
