Simulation wind turbine generator suitable for virtual inertia optimization control research

The invention discloses a simulation wind turbine generator suitable for virtual inertia optimization control research. A simulation wind turbine subsystem is utilized for simulating the actual wind speed changes of the natural world and outputting torque to a grid-connection subsystem of a permanent magnet synchronous generator set, the grid-connection subsystem of the permanent magnet synchronous generator set converts kinetic energy into electric energy and then outputs the electric energy, an inertia simulating device is arranged at the output end of a direct-current motor, the output rotational inertia of the simulation wind turbine generator is increased, not only is the output power characteristic simulation of the wind turbine generator taken into consideration, but also the inertial characteristics of an actual wind turbine generator are taken into consideration, the output rotational inertia is increased, and the inertial characteristics of an actual large type direct-driving type permanent magnet wind turbine generator can be simulated. According to the wind speed modeling mode of an upper computer, the simulation wind turbine subsystem can achieve simulation of the actual wind speed changes of the natural world.
