This invention relates to emulation of wind turbines. An optimum emulator of the steady-state and dynamic characteristics of a wind turbine is proposed. The principal object of this invention is to propose a method and system for enabling testing of a wind turbine energy system (WE-EEC system) in a laboratory environment, over a wide wind velocity range without increasing the rating of the DC motor. Another object of the invention is to have a wind turbine emulator with improved dynamic response which is able to capture the wind sheer and wind shade dynamics more accurately.
