Servo Driver
- Developed specially for turbine pitch applications, combining control and driver functions in one.
- Has abundant I/Os to satisfy the control requirements for megawatt-level turbine generator pitch systems.
- Compact and flexible to install, highly reliable, and able to adapt to adverse conditions in the rotating hub.
- Has auto failure diagnosis functions.
Pitch Motors
- AC induction motor where different power levels can be chosen.
- Automatic execution of safety feathering.
- Comes with heating and cooling functions suitable for adverse conditions in the rotating hub.
Encoder
- The absolute redundancy value encoder is designed to acquire motor positions and blade positions, to boost the accuracy of the pitch.
Standby Power Supply
- Use super-capacitors as the backup power source for the pitch system to overcome shortcomings such as poor battery charge and discharge and high costs.
- Adopted power outputs with high current and wide voltage range to ensure the motor feathers in a reliable manner.
- Has advantages such as being environmentally friendly, does not need maintenance, long-life, and wide-range of operating temperatures.
Power Management System
- Turbine power management system.
- Monitor super-capacitor status and charge it.
