Abstract

The invention relates to a wind power plant simulation modeling method and device for subsynchronous oscillation simulation analysis. The method comprises the steps of respectively determining an electrical parameter and a control system parameter of an equivalent wind power generator set of a wind power plant according to an electrical parameter and a control system parameter of a target wind power generator set in the wind power plant; and inputting the electrical parameter and the control system parameter of the equivalent wind power generator set to a wind power plant simulation model, applying preset disturbance to the wind power plant simulation model within target time to obtain a first simulation result, used for simulating a subsynchronous oscillation phenomenon, output from the wind power plant simulation model. By the method, the simulation modeling time is greatly saved, and the simulation modeling efficiency is improved.

Description

technical field [0001] The present disclosure relates to the technical field of new energy power systems, in particular to a wind farm simulation modeling method and device for subsynchronous oscillation simulation analysis. Background technique [0002] In related technologies, the integration of large-scale new energy into the power system has become an inevitable trend. As a new energy with large-scale development value, wind energy has developed rapidly in recent years, and its installed capacity has increased year by year. Usually, most wind farms are located in remote locations, that is, the wind energy resource concentration area and the load center are in reverse distribution, and the short-circuit ratio of the grid-connected point decreases with the increase of the grid-connected capacity of the wind turbine unit, forming a weak AC system. Large-scale wind farms usually use high-voltage direct current transmission technology or series compensation technology to real...
