Differentiated Innovation

4.1 30% More Power Production

4.1.1 World-leading Centrifugal Pitch-controlled Technology

1. Pitch angle is regulated according to rotor speed to maintain maximum wind power utilization coefficient.

• Positive blade angle is large(+10°) for initial position. Acceleration performance is good. It starts up at low wind speed of 2m/s.
• With below-rated wind speed, monitored rotor speed is regulated at optimal tip speed ratio, realizing high rotor output efficiency.
• With above-rated wind speed, pitch angle is regulated negative, and rotor speed remains around the rated value, realizing stable output power below the upper limit.

1. Working wind speed range is wide.

With wind speed of 3-30m/s (almost all common land wind speeds included), the wind turbine constantly operates without the need for stop protection.

4.2 Smart, Safe, Unattended System

4.2.1 Smart Control 

Based on the cutting-edge electrical control technologies across the world, the main controller center of 20kW pitch-controlled wind turbine is the new-generation smart electrical system integrating the properties of pitch-controlled system. Employing the electrical elements from the top-class factories around the world, the hardware operates stably and has great anti-jamming ability. The software adopts redundant control strategy to ensure safe and reliable operation of the wind power system. With a high expandability, the system is compatible with famous-brand converters and remote modules to meet the one-stop service demand of customers.

1. Smart Protection

The 15 redundant safety protection measures include yawing brake protection from such failures as overvoltage, overcurrent, over-rotating speed and lower pressure, protection by sensors of voltage, current, rotating speed, wind speed and wind direction, emergency brake protection from failures in yawing and pitch-controlled systems, stop under over-wind speed and operation resumption under low wind speed to make sure the wind power system operates safely and reliably.

4.2.2 Smart Safety Protection System

Smart safety protection system is an independent patent technology, which is a pioneer in the industry. It is mainly composed of wind speed detection equipment, smart control system and brake/brake release mechanical assembly.

• It smartly controls operation and stop status of the generator by detecting such signals as wind speed, system voltage, system current and controller status.
• With wind speed of over 30m/s (adjustable), when voltage or current exceeds the rated value or the controller outputs abnormal signals, the smart safety protection system brakes the generator to stop, ensuring safety under abnormal working condition.
• When working condition meets the operation requirement, the system controls the generator to release brake and restart.

4.2.3 Maintenance-free in 3 years Design

1. Long-term protection design in essential parts ensures failure-free operation in a long time. The WTG needs no maintenance in the first 3 years after installation. After 3 years, lubricating grease is added once per year, and the connecting components and the appearance are checked.
2. Double technical measures ensures safe and stable operation.

Pitch-controlled technology and smart safety protection system ensure stable operation under gale working condition, avoiding the impact from the generator on WTG and electrical system due to uncontrolled overload operation.
