This paper describes the instrumentation and control systems for the Teetered Rotor Test Bed (TRTB) wind turbine developed at the University of Texas at El Paso (UTEP). The TRTB instrumentation consists of two real-time data acquisition systems (DAS1 and DAS2). The DAS1 is composed of a battery powered telemetry system housed in a 11″×7″×10″ box mounted on the hub of the teetered-rotor and an IBM-PC as the remote server. This system is designed to collect turbine rotor signals, such as the rotor teeter and azimuth angles, flap and inplane blade bending, and rotor torque. The DAS2 is an industrial-grade PC-based system. It currently acquires signals for wind speed and direction, furl angle (the angle between the horizontal turbine axis and the wind direction ), tower vibration, rotor RPM, power generated, and yaw position. The TRTB wind turbine has an active yaw drive that allows the turbine to be operated in either upwind or downwin configuration. In addition, active yawing also allows the study of wind turbine yaw dynamics at various wind speeds and yaw angles. Two yaw controllers have been implemented and tested on the TRTB wind turbine. The two controllers are a classical proportional-derivative (PD) controller and fuzzy logic controller (FLC). This paper also provides experimental data illustrating the performance of the instrumentation and control system.
