Basically the operation consists of transforming the kinetic energy coming from the wind into electrical energy. They´re commonly used in isolated systems, to power applications in areas far from the power grid. In this case, a method of storing the energy produced is required, for which batteries are used.
Many mini wind systems also use photovoltaic solar panels. In this way, the operation of these mixed solar – wind installations is more stable, guaranteeing a more continuous and stabilized production, both in winter and in summer.
The capacity of the battery must be chosen according to the estimated consumption in the installation and the size of the generator system. As a general rule, you usually choose accumulators with capacity for the installation to have an approximate autonomy of 3 days. In isolated systems, it´s necessary to use a charge regulator, which controls the state of the battery, protecting it against overloads. This is achieved by disconnecting the wind turbine or the panels when they are already loaded.
What is mini wind energy?
Wind energy takes advantage of the kinetic energy of masses of air in motion, that is, the force of the wind.
What it´s made for?
For the production of electricity in large power plants connected to the grid (wind farms), small isolated systems of electricity supply (mini-wind), the pumping of water for supply in isolated areas or for agriculture and wind desalination.
Is it respectful for the environment?
Yes, it contributes to the reduction of greenhouse gas emissions. It doesn´t generate dangerous waste.
What is a mini wind system made of?
There are two types of installations, as in photovoltaic energy.
- Connected to the network:
- Wind turbine
- Electrical installation, low, medium and high voltage lines, transformers, etc.
- Isolated to network:
- Wind turbine
- Energy accumulator
- Charge controller
- Inexhaustible and respect the environment.
- Closedness to the point of generation to the point of consumption, will allows a reduction in load losses.
- It empowers hybrid installations.
- It requires a low maintenance.
- Lack of specific regulations.
- Inadequate remmuneration of tax incentives, which greatly impedes their profitability.
