Small Scale Wind System

A wind turbine, which 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.
In a normal residential application, a home is served simultaneously by the wind turbine and a local utility. If the wind speeds are below cut-in speed (7-10 mph) there will be no output from the turbine and all of the needed power is purchased from the utility. As wind speeds increase, turbine output increases and the amount of power purchased from the utility is proportionately decreased. When the turbine produces more power than the house needs, the extra electricity is sold to the utility. All of this is done automatically. There are no batteries in a modern residential wind system. Small wind systems for remote applications operate somewhat differently.
Most small turbines have very few moving parts and do not require any regular maintenance. They are designed for a long life (up to 20 years) and operate completely automatically.

The system diagram as follow:

System includes:

1. Wind turbine: which 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.

2. Wind controller:

3. 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.

4. Inverter: A power converter that "inverts" the DC power from the panels into AC power.The characteristics of the output signal should match the voltage, frequency and power quality limits in the supply network.

5. 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).

Wind/Solar hybrid System

Hybrid Systems - Utility Connected with Battery Backup:??A combination of the above systems, these applications have the advantages of both.They are connected to the utility grid in case the weather is insufficient for the solar or wind system, but they also have batteries to store electricity in case the utility grid goes down as well.The design and installation of these systems is more complicated and expensive,but they are the most effective in providing constant,reliable electricity.

The system diagram as follow:

System include:

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: which 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. Solar controller: control battery bank charge and discharge reasonable and safety.

4. Wind controller:

5. 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.

6. Inverter: A power converter that "inverts" the DC power from the panels into AC power.

7. 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).
