Technical Parameter of JD 5.0-5000 5KW Wind Turbine System
1. Features
1.1. Optimum aerodynamic shape design: High efficiency, low noise.
1.2. Centrifugal pitch controlled mechanism: 2m/s low wind speed startup; 3-12m/s wind speed, following wind rotor rotate speed to adjust blade angle at optimum TSR, run in high efficiency; Over rated wind speed, wind rotor never goes to over speed and has stable control; 3-25m/s wind speed, wind turbine can run smoothly
1.3. Direct drive permanent magnet generator, low startup resistance moment, constant running ability of over loading 1.5 times, maintenance free for more than 30000 hour.
1.4. Safety control: Has aerodynamic brake, electric magnet brake, mechanical brake and manual stop mechanism
1.5. Sealed slip ring, no cable twist
1.6. Long acting anticorrosive treats, no corrosion in 15years.
2. Pitch controlling Principle
Rotating speed change of wind rotor drives the centrifugal pitch control mechanism to adjust blade pitch; Wind pressure on wind rotor will reduce, and then wind turbine rotating speed slow down. Close loop control, reliable regulation. Pitch control mechanism is sensitive, reliable, and can be used in variable environments
Wind turbine start up: Keep a big blade pitch, start up with 2m/s wind speed; Wind turbine start to run: Reduce blade pitch step by step, better for speedup; 4-12m/s wind speed: Regulate the optimum blade pitch to keep the max output power of wind turbine; Encountering to strong wind: Adjust blade pitch into negative angle to keep rotating speed within limits; Manual stop: Operate manual winch to adjust blade pitch into negative angle, blade will lose it aerodynamics, start mechanical brake to stop wind turbine.
