Abstract
The application provides an online parameter self-adaptive correction method for eliminating steady-state and transient-state errors of an offshore wind farm aggregation model, which comprises a wind speed aggregation module, a plurality of wind turbine aggregation modules, a plurality of transformer aggregation modules, a plurality of power collection cable aggregation modules and a self-adaptive parameter calculation module. According to different operating states of the wind turbine, the wind turbine aggregation parameters and the power collection cable aggregation parameters can be calculated in real time, and finally a high-precision simulation wind farm aggregation model is formed under the condition of variable wind speed and operating mode, so that the steady-state and transient-state precision of the dynamic aggregation model of the wind farm is improved.
