Fault simulator for wind turbine control system, and method of simulating fault of wind turbine control system

摘要

PURPOSE: An apparatus and method for simulating faults in a wind power generation system are provided to simulate and test the faults in the system. CONSTITUTION: An apparatus for simulating faults in a wind power generation system includes an electric motor (101), a fault generator (200), an electric motor controller, and an electricity generator controller (400). The electric motor drives an electricity generator. The fault generator converts wind velocity data into a wind velocity normal signal or a wind velocity fault signal using a fault generation data model. The electric motor controller controls the rotational speed of the electric motor in response to the wind velocity normal signal. The electricity generator controls the torque of an electricity generator in response to the wind velocity normal signal or the wind velocity fault signal.
