The invention relates to a construction method and an impedance characteristic evaluation method for a real-time simulation model of a wind power plant station, and the method comprises the steps: constructing a stand-alone functional model of a wind turbine generator in a wind power plant through an interface variable alternation mode between an FPGA simulation machine and a CPU simulation machine, and reducing the construction order of the simulation model of the wind power plant; the modeling flexibility is kept while the simulation efficiency is improved; a wind power plant functional model is constructed by adopting an assembly line algorithm to realize efficient simulation of a large number of wind turbine generators in a wind power plant, and a single-machine functional model of fan functionality is corrected by utilizing disturbance test data based on fan converter controller hardware in-loop actual measurement and parameter identification; the wind power plant functional model of the functional stati
