Wind turbine 1 kW, AC, 3ø

The Efficient Solar House has a small wind turbine with a nominal power of 1000 W, alternating current (AC), three phases (3Ø). This machine, installed at 12 meters high, was added in October 2006 to the Solar House's generation system in parallel with the photovoltaic generation system.

The turbine consists of a rotor comprising the blades and the hub, driven by the wind that drives an asynchronous generator, generating AC electricity. The output voltage of the wind turbine is then converted from AC into direct current (DC) through an electronic converter called a rectifier, and it feeds the battery bank with the operating voltage of 48 volts DC. The power in AC of Solar House's equipment (like those found in a conventional house) is made from the load controller, but before that the output voltage is converted from DC to AC by a voltage source inverter.
