1 Scope

GB/T 42599-2023 specifies the validation of the electrical simulation models of wind turbines and wind farms. Grid operators plan and study the system on models, and for a network with as much wind as China's the results are only as good as the wind turbine models fed into them: a model that does not reproduce what the machine actually does during a voltage dip will predict a stable system where the real one collapses. Validation means comparing the model against measurements from the machine under defined disturbances. The standard sets the model validation procedure requirements for the turbine and for the wind farm, and the general methods of validation, covering the test results, the simulation and the comparison and acceptance criteria between them, with an annex giving the simulation model and validation information and a result template. It took effect on 23 May 2023.

This document specifies the verification procedure for electrical simulation models of wind turbines and wind farms for power system and grid stability analysis: The test data for model verification is obtained according to the IEC 61400-21 series of documents: This document applies to the general model and other fundamental frequency wind turbine and wind farm models: The wind turbine model verification project includes fault ride-through capability and control characteristic simulation verification: Fault ride-through capability including wind power generation The unit model responds to voltage drop and voltage rise under balance and unbalance: Control features include active power control, frequency control, inertial Quantity control and reactive power control: The test data used for the verification of the wind turbine model is based on the test procedures specified in IEC 61400-21-1: The certificate is at the output end of the wind turbine: Since IEC 61400-21-2, which specifies the content and methods of wind farm testing, is still in the preparation stage, this document does not specify wind power in detail: The reference point for wind farm model verification is the wind farm access point (hereinafter referred to as "grid connection point"):

Note: The wind farm access point is also called the grid connection point of the wind farm: The model verification procedure specified in this document is based on the comparison of test data and simulation data, and the verification results do not depend on the selection of simulation software:
