HYBRID POWER GENERATION BY SOLAR –WIND

INTRODUCTIONIt is possible that the world will face a global energy crisis

due to a decline in the availability of cheap oil andrecommendations to a decreasing dependency on fossil fuel.This has led to increasing interest in alternate power/fuelresearch such as fuel cell technology, hydrogen fuel, biodiesel,solar energy, geothermal energy, tidal energy and wind. Today,solar energy and wind energy have significantly alternated fossilfuel with big ecological problems.

COMPONENTS OF HYBRID GENERATOR Solar panel

Controller

Monitors the system starting and stopping engine as need

Why we use MPPT Charger Controller

•Consider solar panel Kyocera KC 130. It is rated at 7.39 𝐴𝑚𝑝𝑠 at 17.6

It’s power output is 130 Watts .

•Panel puts out 7.39 𝐴𝑚𝑝𝑠 & battery charges under 12V

• 7.39 𝐴𝑚𝑝𝑠 * 12V =88.8 Watts

• We lost over 41 Watts. But we paid for 130 Watts.

• To overcome this loss, we use MPPT Charger Controller.

Working of MPPT Charger Controller

•Controller compares voltages of PV panel & Battery

•Figure out best voltage to charge Battery

• Example: Controller takes 17.6 Volts at 7.4 𝐴𝑚𝑝𝑠 & gives output to10.8 𝐴𝑚𝑝𝑠 at 12Volts .

10.8 𝐴𝑚𝑝𝑠 * 12Volts = 129.6 Watts

• Now we still have almost 130 Watts.

Batteries

Stored the energy

Inverter

Converts stored DC power to AC

WORKING

Solar & Wind turbine produced DC power

Inverter convert DC to AC

Controller monitors the system

CHOICE OF COMPONENT Choice of components For 1000 Watt Load

Solar Panel: • Total load = 1000W •Period of operation or duration = 12 Hours •Then, Total Watt-Hour = 1000×12= 12000W-hr •The period of the solar panel exposed to the sun = 8 Hours (Averagely between 9am and 3pm) •Therefore solar panel wattage = 12000𝑊ℎ/8ℎ=1,500𝑊. •Hence solar panel of 1,500W will be needed for this design. •If solar panel of 150W is to be use the number of panels to arrange in parallel to achieve 1,500 Watt will be: No of panel =1500W/150𝑊=10 This shows 10 of 150 Watt solar panel will be required for this design

Charging Controllers:

For this design of 1000W solar power supply P=IV

Where

I is the expected charging current and

V is the voltage of the battery and V= 12 V

P is the power supply rating= 1000W

Hence I =𝑃/𝑣=1000/12=83𝐴𝑚𝑝𝑠.

Since the value 83.3 A Charging controllers is not readily available in the market then 1000A charging controller will be used.

Battery capacity:

Given that the total load P= 1000W and Operational period = 12 Hours

Watt-hour capacity = 12,000 W-hr To make the chosen battery to last long it is assumed that only a

quarter (¼) of the battery capacity will be made used of so that it will not be over discharged therefore hence the required batter capacity will be

12, 000 × 4 = 48,000 W-hr Now the choice of battery hour depends on A-H rating of the

storage battery. For example 1500AH, 12V batteries the number of batteries that

will be needed is 48000/1500 = 32 batteries. Hence, for this design , 1500AH 12V battery should be used, Therefore the total number of storage battery required for 1000W solar power supply system = 32

Inverter

Since the total load is 1000W it is advisable to size the required inverter to be 1500W as designed for solar panel ratings. Hence 1500W pure sign wave inverter is recommended in other to prolong the lifespan of the inverter.

APPLICATION Hotels

Business (Institutions and Government)

Large Estate Houses

Factories and manufacturing facilities

Commercial Power generation

Street lighting

ADVANTAGES Very high reliability (combines wind power, and solar

power) Long term Sustainability High energy output (since both are complimentary to each

other) Cost saving (only one time investment) Low maintenance cost (there is nothing to replace) Long term warranty No pollution Clean and pure energy Provides un-interrupted power supply to the equipment The system gives quality power out-put DC to charge

directly the storage battery or provide AC. The system can be designed for both off-grid and on grid

applications. Efficient and easy installation, longer life

DISADVANTAGES Large number of harmonics is produced.

Initial investment is more.

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.

CONCLUSION By this project many villages can be lighted. For villages which

are much away from the construction site of large power generating stations such as hydro and nuclear can be provided power.

Also to satisfied the increasing demand of electricity with clean hybrid power station by solar –wind can be used.
