i-Pitch System

The i-PITCH design is directed to serve the latest wind energy market demands as well as the ones anticipated to emerge and develop in the future. Naturally, as a Windurance engineered product, the new i-PITCH is modular and easily adapted to any utility grade wind turbine that is 2.5 MW or larger.

i-PITCH is a family of interconnected and interoperable, processor and network based, closed loop servo power conversion controls, motors, and auxiliary power technologies that are specifically designed for the full span blade pitch application in multi-megawatt wind turbines. These technologies are housed in compact modules that are easy to identify, install and replace. i-PITCH provides a computing, sensory, and high dynamic performance blade pitch control platform to enable the most advanced turbine control techniques and algorithms to be executed at the pitch system level.

The most significant feature/benefit from the new i-PITCH system is availability. This system was engineered to respond to the most significant of issues and harsh conditions that affect utility grade wind turbines.
