Advantages of wind energy

Lower operation and maintenance cost.No Conventional fuel required.Technically Simpler.Environmental friendly.

METHODOLOGY

Solar panel or photovoltaic (PV) cells has absorbed sun beam by radiation and gives electric energy output.

Solar panels are the medium to convert solar power into electrical power.

A wind turbine obtains its power input by converting the force of the wind into torque (turning force) acting on the rotor blades.

The amount of energy which the wind transfers to the rotor depends on the density of the air, the rotor area, and the wind speed.


METHODOLOGY

Both system (Solar & Wind turbine) has produced DC power.

The both electric power has stored in the battery by battery charger.

Both power has controlled by inverter (DC/AC) and supply to the lighting system.

BatteryThe storage battery or secondary battery is such battery where electrical energy can be stored as chemical energy and this chemical energy is then converted to electrical energy as when required.


Fig. 14 Battery

InverterInverter, is an electronic device or circuitry that changes direct current(DC) to alternating current (AC). The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry.

ADVANTAGES OF HYBRID SYSTEMIt is free and available in adequate

quantities in almost parts of the world where people live.

It is an inexhaustible source of energy.Wind-Solar energy is available whole

year.The setup device is very simple.


The Win-solar energy conversion system is more stable.

It requires a little maintenance and Operation cost.

Easy installation method.Environmental friendly.The cost to produce unit power is

comparatively lower than other renewable energy.


ADVANTAGES OF HYBRID SYSTEM

DISADVANTAGES OF HYBRID SYSTEMLarge number of harmonics is produced. Large space is required for larger

generations. Wind energy systems are noisy in operation,

a large unit can be heard many kilometers away.

Efficiency is less than conventional power plants.


APPLICATIONS OF HYBRID SYSTEM

RURAL AREA

APPLICATIONS OF HYBRID SYSTEM

OUTCOMES FROM HYBRID SYSTEM

To get electricity from wind-solar power generation system.

It helps a small part of the daily electricity consumption with an efficient utilization.

This project can be implemented in rural areas where the power cut-off is regular.



CONCLUSIONThe main objective of this project was to give more stable power from wind–solar hybrid system. The project has been successfully designed & constructed, which is able to collect sun radiation and wind velocity all the day to operate the system. It can be commercially applicable in village and remote areas where air velocity and sun radiation is perfectly available.
