Research Topic- Farmer Friendly Solar based Electric Fence

Electric fences can be used to protect farmhouses, farmlands, forest bungalows, etc from animals. These control the animals by giving them a short, sharp but safe shock that makes them to stay away from the fence. Thus electric fences are economical and better solutions to maximize field production through controlled grazing. Electric fencing is safe, as its discrete (not continuous).

This fence system is powered by a 12V rechargeable battery. A solar panel is connected to the battery to charge on day time. The battery is connected to the inverter. This inverter is used to convert the 12v DC to the 230v A C. The 230v AC voltage is used to activate the loads. Here we are also using Conventional Battery Charger unit to rechagre the battery. AT89s52 micro controller is the heart of the circuit as it controls all the function. A voltage sampler is interfaced with the system using A 0808 to get the DC voltage generated from solar panel stored in battery as a display on a 16x2 LCD. A 12v DC lead acid rechargeable battery is used for storing the energy. We are using conventional battery charging unit also for giving supply to the circuitry. This Conventional power source uses regulated 5V, 500mA power supply. 78o5 three terminals voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the AC output of secondary of 230/12V step down transformer.

There has been a number of ideas or views present about renewable sources of energy But it is important to calculate about what is the for ratio of extract energy through the turbine and what is the ratio of energy which involves to provide energy to pump or other sources. The drawbacks are efficiency and durability will be high but it depends upon the area of water and turbine. Alternately we are using solar panel and also wind turbine for better efficiency of electricity of complete cycle.

The major requirements of this complete cycle are water sources, turbines, electric motor, pump, solar panel, tubes and alternator.This project can be used for large scale as well as small scale purposes this all equipments are used sequence as per required.
