Control unit of wind turbine for 12 V battery charger

Abstract

Energy produced by wind turbines does not produce pollutants like other sources of energy (i.e. coal, gas, and petroleum based fuel). Wind energy may help to reduce the air pollutions by replacing the current sources of conventional energy. As a result, emissions especially carbon dioxide, nitrogen oxide and sulfur dioxide can be reduced. Environmental concerns including the growing global climate change has prompted a spurt of growth in the application of small scale and large scale wind power generation applied across the world today. The large scale wind turbines are to provide electric power to supply grid. Small scale wind turbines are typically used in battery charging system in off and remote grid connections to provide electric power to small load locations such as homes and cabins. Therefore, use of control unit required for wind turbine system to ensure that the operation of voltage in and out from the wind power source to the battery system to run properly. The project discuss about the application of Control Unit of Wind Turbine for 12 V Battery Charger. DC power supply as a power source from the 12 V batteries. An amount of voltage incoming from source will be monitored by the control unit. The system consists of charge controller and 12 V Lead Acid Battery. For battery application, a function of the charge controller is used to monitor the voltage battery in the system, to recharge them, or dumps the power from the turbine into dummy load if the battery is fully charged. PSIM 9 is used for simulation of the circuits.
