Experimental Emulation of a Small Wind Turbine Under Operating Modes Using DC Motor

This paper describes the experimental implementation of a physical simulator of a small wind turbine using a controlled DC motor of 1.5 kW. The emulation principle requires the application in real time of a random wind speed profile on an operating static-dynamic wind turbine model, in order to generate a driving torque identical to wind turbine but using a DC motor with a current control loop. The DC motor is controlled through a chopper. The test bench is driven by a dSPACE DS1104 control board using RTLib and C language program for system modeling and control loops (DFIG and DCM). The experimental results confirm the effectiveness of the actual simulator during hypo-synchronous mode, hyper-synchronous mode, and when switching between them.
