WIND ENERGY

	Wind Energy Resource Assessment
	1MW Dual-Rotor WInd Turbine

As global warming & climate changes in the recent world, renewable energy became alternative solution for most of the countries. In this part of the world, frequent changes in wind direction, severe wind storm, low speed, and frequent breakdown of equipments are the few core issues to decrease the wind power efficiency.

Our principal - Kowintec engineered world-wide patented T-type bevel planetary gear and Dual-Rotor structure into its solely designed wind power system with outperforms to conventional wind turbine system. Dual-Rotor Wind Turbine system has proven to be more effective and significant maintenance cost reduction in contrast to single-rotor wind power system.

Compensates Dead-Zone
The Dead-Zone is an area of 30% of the blade from the center axis, which no wind energy can be converted into machanical energy. In Dual-Rotor Wind Turbine, the Dead-Zone is compensated by adopting an auxiliary rotor blades in the system. It increases the tip speed of the main rotor system.

Real-Time Yawing Control System
The conventional wind power systems depend on yaw motor to react on the changing of wind direction. This result in lower power efficiency due to the electrical and machanical lost and frequent break down. Our principal engineered free yaw control system to react real time to the wind directions for better accuracy. It also protects the wind turbine by absorbing severe impact and minimizes system damage from strong wind storms.

T-type Bevel-Planetary Gear System
Our principal has acquired world-wide patent on its T-Type Bevel-Planetary gear system. This innovative design enabled free yaw and allowed the generator to be seperated from the nacelle and installed inside the tower.
