The invention discloses an actually-measured data based modeling method for an active power and reactive power control system of a wind-light power storage station. The method comprises the following steps of acquiring and classifying data of each single device of a large-sized wind-light power storage station, and acquiring the number of single stations, active power adjustment capacity, time and adjustment accuracy of the single stations, and reactive power adjustment capacity, time and adjustment accuracy of the single stations; separately building a wind power plant model, a photovoltaic power station model and an energy storage power station single-station model for the large-sized wind-light power storage station; building an integrated circuit model, a main transformer model and an equivalent circuit model for the large-sized wind-light power storage station, adjusting parameters of a static var generator (SVG), a static var compensator (SVC), a capacitor bank and a reactor bank so that the external characteristics of the SVG, the SVC, the capacitor bank and the reactor bank are consistent with the actual working condition of the large-sized wind-light power storage station; and carrying out time-domain simulation on the above models to acquire a layered control system model of the large-sized wind-light power storage station.
