ET 220 Energy conversion in a wind power plant

GUNT ET 220

Wind Power Plant is a laboratory-scale system designed to demonstrate the conversion of kinetic wind energy into electrical energy. The unit operates independently, simulating real-world wind power generation. An axial fan with adjustable speed generates wind, while a flow straightener ensures uniform conditions. The generator converts mechanical energy into electrical energy, which is then stored in an accumulator and used to power two 12V bulbs as electrical loads. The system enables measurements of wind velocity, rotor speed, voltage, and current, with values displayed digitally.

The ET 220 features remote learning capabilities, providing an E-Learning course on wind power basics. It also supports networked experiments, allowing multiple workstations to observe, acquire, and analyze data through the GUNT software, either via USB or the user's LAN/WLAN network.

This system provides a comprehensive platform for studying wind energy conversion, making it ideal for education, research, and technical training in renewable energy technologies.
