Development of Real­time based Hardware­In­Loop Simulator for performance evaluation of wind turbine control system

This paper proposes a Hardware-In-Loop(HIL) Simulator for aWind Turbine and an operational control algorithm to evaluate the performance of a wind turbine control system. It provides not only for the validation of the control logics, safety functions and H/W failure, but also for the high reliability of the wind turbines (by reducing/and the reduction of?)the operating expense(OPEX) through performance evaluation tests with complex scenarios. On the other hand, the proposed simulator uses MATLAB, CODER, and the PLC library to operate in synchronization with the hardware, and a real-time processing-based wind turbine module including a dynamic model and control system, wind module, grid module and host PC to manage the HIL-simulator. Several experiments werecarried out under the above concept toverify the effectiveness of the proposed WT HIL-simulator.
