Abstract

Aiming at the problems of inaccurate wind turbine model, limited simulation scale, long simulation time, and low efficiency in the process of wind farm grid connection simulation, a HYPERSIM-RTLAB co-simulation method and interface delay compensation method are proposed. In the proposed method, the power grid model is built by HYPERSIM software, which can carry out real-time simulation of power grid electromagnetic transient. At the same time, the digital-analog hybrid simulation model of wind farm with wind turbine controller is built through RTLAB. which solves the problem of inaccurate simulation of general model. The transmission interface delay between platforms is quantitatively studied, and a co-simulation decoupling method with delay compensation is proposed to complete the joint electromagnetic transient simulation of wind farms connected to the power grid. Finally, the effectiveness and accuracy of the decoupling method is verified by comparison with the distributed line model, and the fault analysis of the wind power grid-connected co-simulation is carried out. The simulation results show that the co-simulation platform can accurately and effectively reflect the real characteristics of wind power grid-connected.
