Residential wind turbine SWT5kw
SWT5kw-5.6 is one of the down-wind centrifugal force controlled passive variable pitch wind turbine series designed and follows BWEA standard. Product quality has been well controlled by following ISO9001 standard. Ever since accessed to the international market in 2010, it has performed excellently with good power generating, durability, safety, quick installation, easy maintenance, compact structure and streamline appearance.
Variable Pitch Mechanism
Blade angle is positive 4 degree as factory setting at which the turbine is easy to start spinning. After the turbine starting running ,the angle of blades turns to 0 degree quickly, and the blade acts at its most efficient point (one spring acts). It outputs 5kW electrical power at 10.5 m/s wind speed with 240 rpm rotor rotation speed. If the wind speed increases,the blade is forced to turn towards negative angle by centrifugal hammers to limit rotation speed (two springs act). The springs balance the blades angle and rotation speed while regulating power generating.
Connect the out going cables to the terminals at the bottom of the generator, and elicit the cable from outlet of the bottom of the tower.
Blades and HUB
A) Install the blades on the hub and make 3 pieces M8*25 bolt fasten.
B) Put the hub onto the shaft and make M16 nut fasten, at the same time turn the blades clockwise till the hub connect the shaft tight.
1. PV Array: A number of PV panels connected in series and/or in parallel giving a DC output out of the incident irradiance. Orientation and tilt of these panels are important design parameters, as well as shading from surrounding obstructions.
2. Wind turbine: This is installed on top of a tall tower, collects kinetic energy from the wind and converts it to electricity that is compatible with a home’s electrical system.
3. Hybrid controller: control battery bank charge and discharge reasonable and safety.
4. Battery bank: can be a single battery or multiple batteries connected together to create essentially one large battery of the required voltage and amp-hour capacity. In some ways the battery configuration and capacity are the most important electrical power decision to make, and a wise choice can help guarantee a steady supply of electrical power as well as a system that is simple to operate and maintain.
5. Inverter: A power converter that inverts the DC power from the panels into AC power.
6. Loads: Stands for the network connected appliances in the building that are fed from the inverter (AC loads), or from the battery bank (DC loads).
