Overview
The purpose of IEC 61400-27 is to define standardized dynamic simulation models for wind turbines and wind power plants intended for mains and grid stability analyses and should be applicable for dynamic simulations of mains events such as short-circuits (grid support during voltage dip), loss of generating capacity or loss of load, and grid disconnection. The proposed tasks lead to the development of a two-part standard with the following scope. IEC 61400-27-1 specifies dynamic simulation models for generic wind turbine topologies/ concepts / configurations on the market. The standard defines the generic terms and parameters with the purpose of specifying the electrical characteristics of a wind turbine at the connection terminals. In addition, the standard establishes a procedure for creating models for future wind turbine concepts. IEC 61400-27-2 specifies dynamic simulation models for the generic wind power plant topologies / configurations on the market including wind power plant control and auxiliary equipment. In addition, the standard specifies a method to create models for future wind power plant configurations. Both standards include validation procedures for the specified electrical simulation models. The electrical simulation models are related to the wind turbine terminals, and for wind turbines the reference point is the point of common coupling (PCC). The validation procedures in Part 1 include tests according to the specifications in IEC 61400-21, second edition, with emphasis on the response to voltage changes and set point changes. The electrical simulation models specified in this document are independent of any software simulation tools. The present document is Part 1 of IEC 61400-27. The responsible committee is DKE/K 383 "Windenergieanlagen" ("Wind turbines") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
