Abstract :
In this paper, a new type of wind turbine simulator (WTS) based on DSEM (doubly salient electro-magnetic machine) is proposed to simulate the steady-state and dynamic characteristics of a wind turbine in direct-driven DSEG (doubly salient electromagnetic generator) wind power generation system. A simple and effective torque control strategy is proposed to realize torque closed-loop control of DSEM which reproduces the torque versus rotating-speed characteristics of a wind turbine. Torque compensation methods for different moment of inertias and friction coefficients are also adopted to ensure the same dynamic performances of the simulation system and an actual system. Pulsations caused by variable wind speed, wind shear and tower shadow effects are also taken into account to ensure an accurate simulation of the mechanical performance. Simulation results demonstrate that the proposed WTS is capable of fast response and precise reproduction of the dynamic behavior of an actual wind turbine-generator system, which lays the foundation for future studies of direct-driven DSEG wind power generation system in the laboratory.
