Nacelle-Wind Turbine Training System

The Nacelle – Wind turbine Training System is a complete scaled-down version of commercial wind turbine nacelles, making it an excellent substitute for expensive real-life equipment. Space efficient and affordable, the machine fully interacts with users, thus enhancing the learning experience.

The training system consists of a complete drive train that includes the main shaft, a gearbox with a transparent side cover, speed sensors, a hydraulic brake, and an asynchronous generator. The yaw system is fully operational and features a 61 cm (24 in) slewing bearing, a gear motor, a drive, a position sensor, and fail-safe hydraulic brakes. A manual hydraulic pump and an accumulator, as found in real-world wind turbines, are also included. A PLC controls the different functions of the nacelle and is located in an electrical enclosure together with all the other electrical components.

A wind vane and an anemometer are located in a transparent enclosure on top of the training system to monitor wind speed and wind direction. Although they are not measuring actual wind, the control system managed by the user simulates the process, causing the weather sensors to react and send signals to the control system which take the simulated parameters into account.

The Nacelle – Wind Turbine Learning System features a three-phase induction generator that can produce power. It can be considered a mechanical load unless it is connected to a grid. The optional Power generator creates such a connection, enabling the system to produce electricity. Students can then measure and monitor several actual (not simulated) electrical parameters, such as VAR, W, VA, power factor, etc.
