摘要

With the rapid development of the wind power generation, the penetration rate of wind power is gradually increasing, which affects the stable operation of the power system. The DFIG wind turbine generator can realize decoupling control of output active and reactive power by vector transformation control. However, under this power control, wind turbines do not have the electromechanical transient characteristics like synchronous generators for supporting the stable operation of the power system. Virtual synchronous generator technology can make the wind power system reflect the operation mechanism and external characteristics of traditional synchronous generators to improve the stability of power system. This paper builds a generic simulation model of current source type DFIG wind turbine generator based on VSG technology, which can simulate a series of VSG behaviors including virtual inertia control, damping control, primary frequency control, reactive power control and fault ride through. The developed simulation model is also validated comparing to the actual wind turbine field testing data, which shows accurate and reliable simulation results. The developed simulation model can provide theoretical and model basis for studying VSG technology and grid integration characteristics.
