UNE-EN IEC 61400-27-1:2020

IEC 61400-27-1 defines standard electrical simulation models for wind turbines and windpower plants. The specified models are time domain positive sequence simulation models,intended to be used in power system and grid stability analyses. The models are applicablefor dynamic simulations of short term stability in power systems.IEC 61400-27-1 defines the generic terms and parameters for the electrical simulationmodels.IEC 61400-27-1 specifies electrical simulation models for the generic wind power planttopologies / configurations currently on the market. The wind power plant models include windturbines, wind power plant control and auxiliary equipment. The wind power plant models aredescribed in a modular way which can be applied for future wind power plant concepts andwith different wind turbine concepts.IEC 61400-27-1 specifies electrical simulation models for the generic wind turbine topologies/concepts / configurations currently on the market. The purpose of the models is to specify theelectrical characteristics of a wind turbine at the wind turbine terminals. The wind turbinemodels are described in a modular way which can be applied for future wind turbine concepts.The specified wind turbine models can either be used in wind power plant models or torepresent wind turbines without wind power plant relationships.The electrical simulation models specified in IEC 61400-27-1 are independent of any softwaresimulation tool.
