1KW Wind Power Turbine Generator VAWT | Summary

This advanced Vertical Axis Wind Turbine power generation system is connected to an existing power system using a power conditioner. It has a fully integrated automatic braking system to maintain steady and continuous power generation and to protect against high wind gusts or severe weather conditions.

The power output through the power conditioner is single-phase three-wire 100/200V (50/60Hz). A power conditioner is available for those who wish to have triple-phase output.

There is no need to have to maintain batteries as this wind power system works in conjunction with your existing power grid. If you want freestanding load operation (Off Grid) that uses a battery or other storage system, please select a different model.

Performance - Interconnected System

The power generated by the wind turbine generator is converted from AC to DC by a rectifier, and is boosted to the power conditioner's operating voltage by a DC/DC converter. The boosted power is converted from DC to single-phase three-wire AC (100/200V) by the power conditioner, and is interconnected to an existing power grid and used as ordinary commercial electricity.

Both the DC/DC converter and power conditioner have power load adjustment on both the input and output ends to supply power to the grid that matches the wind speed.

Brake System

This is an electrical brake system that controls rotation when the wind speed exceeds the system's rated rotation speed in order to continue generating power.

When the turbine rotates faster than its rated speed due to sudden changes in wind speed such as gusts, the signal from the voltage detector (VD) causes the electrical brake to operate, thereby decreasing the rotation. When the turbine's rotation drops below its rated speed, the electrical brake is automatically released.

For maintenance, the electrical brake can also be applied manually to stop operation.
