Components of Hummer 30KW Grid tied Wind Turbine Generator:
1. Generator Part
It is composed of the patented SCF generator, the nose cone, and the protection cover. Hummer adopts the state-of-the-art SCF supercritcial generator, which is installed in the hub, easy to radiate heat and reduce wind resistance. Made of high-efficiency magnetic materials, special copper alloy, high-strenghth stainless steel and aeronautic aluminum alloys, which is extremely light in weight and small in size, but with higer power producing efficicency.
2. SKF Bearings
Two SKF bearings ensure the reliability the longevity of our generator. Wide temperature ranges: Operation in the high temperature (150-350º C). Long life span, reach up to 60000-100000 hours. User may not change the bearing during the wind turbine using. It can greatly reduce the maintenance costs.
3. Flange & Blades
The flange is made of fine steel, used to fix the blades to the rotor. The blades are made of glass reinforced plastic, efficiently turn the wind energy into the mechanical energy. Every set of the three blades has passed the strict balance test before the shipping. It is important to fix the blades together which belongs to one set to the flange and never mix them up with other blades which belongs to another wind turbine.
4. Yaw Shaft
It is made of fine steel and used to connect the generator and the blades to the tower. Powered with a 24V motor and integrated with a gear box, which are able to regulate the direction of the generator.
5. Dogvane & Anemometer
They receive the signals of the wind direction and the wind speed.
The dogvane reads the average value of the wind direction every 120 seconds. If the angle between the dogvane and the wind generator axis depasses 10° , the 24V motor will drive the yaw shaft to turn and follow the wind direction automatically.
The anemometer mesures the realtime wind speed. If the wind blows non-stop over 3m/s during 20 seconds, the automactic wind tracking program will start to make the rotor blades surface face the wind correctly.
6. On-grid Inverter
Hummer on-grid inverter adopts MPPT (Maximum Power Point Tracking) technology and IGBT (Insulated Gate Bipolar Transistor), is able to invert DC with a high power producing capacity and a wider AC voltage output range. It connects to the public grid and there is no need for any power storage device.
7. Siemens Module PLC
Hummer PLC (Programmable Logic Controller) adopts the Siemens controlling module and is equiped with a touch screen. It can alarm and adjust the abnormal running status of the wind turbine automatically. Siemens module offers high reliability to our PLC and its customers worldwide can testify for that. It easy to control and operate your wind turbine via our PLC easily and efficiently.
8. Rectifier/Dump Load Controller & Dump Load Box
The controller controls the process of which the alternative current produced by wind turbine into direct current and eventually charges the battery bank with DC. It also controls the switching on and off of the dump load to protect the system against the risk of being overloaded with too much power.
Metal box design of the dump load radiates the heat of the resistance inside quickly via the air convection. So there is no need for an extra fan.
