The embodiment of the invention discloses a microgrid semi-physical simulation system and a closed-loop control method of a wind generator. The microgrid semi-physical simulation system comprises an input parameter control module, a wind generator simulation module and a grid connection module, wherein the input parameter control module is used for transmitting an input parameter, obtained through simulation, of the wind generator to the wind generator simulation module; the wind generator simulation module is used for carrying out simulation operation according to the received input parameter; and the grid connection module is used for controlling the wind generator simulation module to be connected to a microgrid simulation source and a local power grid. According to the semi-physical simulation system for wind power generation closer to the actual condition, the error generated in the simulation process is reduced, a variable wind environment can be simulated, and meanwhile, the accuracy of the simulation
