- 2. OUTLINE • Introduction • Methodology • Calculation • MATLAB • Future Plan • Problems we faced
- 3. INTORDUCTION • An automatic weather station (AWS) is an automated version of the traditional weather station, either to save human labor or to enable measurements from remote areas. • It contains the data logger, rechargeable battery and the meteorological sensors with an attached solar panel or wind turbine and mounted upon a mast.
- 5. SENSORS IN METEOROLOGY STATIONS Most automatic weather stations have: • Thermometer for measuring temperature. • Anemometer for measuring wind speed. • Wind vane for measuring wind direction. • Hygrometer for measuring humidity. • Barometer for measuring atmospheric pressure. Some stations can also have: • Ceilometer for measuring cloud height. • Present weather sensor and/or visibility sensor. • Rain gauge for measuring liquid-equivalent precipitation. • Ultrasonic snow depth sensor for measuring depth of snow. • Pyranometer for measuring solar radiation.

- 15. CALCULATING OUTPUT POWER FOR TURBINES 1 MW Wind Turbine: “WinWind Turbine” • Power Coefficient = 0.75 • Area = 2826 m^2 • Area was calculated by using the following equation • assuming the diameter equal 60 m so r will be 30 m. • We have = 1.23 100 KW Wind Turbine: “P21-Polaris” • Power Coefficient = 0.75 • Area = 415.265 m^2 • Area was calculated by using the following equation • assuming the diameter equal 21 m so r will be 11.5 m. • We have = 1.23

- 18. SOLAR ENERGY CALCULATION Assuming we need to cover a load of 10000KWH • Epv = Penetration Factor * E load • = 0.2 * 10000KWh • Epv = 2000KWh • Ppv= Epv/ (P.S.H * Efficiency %) • = 2000/ (5.4*0.95) • Ppv =390 KW • Number of modules = Ppv/ Ppeak
- 19. TYPES OF SOLAR CELLS • Taking P peak in two cases: • P peak = 150W -12 v- Mono type. • P peak= 200w – 24 v – Poly type.
- 20. P PEAK = 150W -12 V- MONO TYPE. • For Mono type Number of modules needed = 390KW/150W = 2600 Modules • Taking Vdc = 400 V • Number of modules in one string = 400V/ 12V =34 Module • Number of strings = 2600/33.33= 78 String
- 21. P PEAK= 200W – 24 V – POLY TYPE. • For Poly type Number of modules needed = 390KW/200W = 1950 Modules • Taking Vdc = 400 V • Number of modules in one string = 400V/ 24V =17 Module • Number of strings = 1950/16.67= 117 String
- 22. MATLAB • We designed two programs by using the “guide function” in MATLAB. • The First Program “Wind Power Calculator” calculate the output power from the wind turbines • The Second Program “ Modules Calculator” calculate the photovoltaic energy, photovoltaic power, number of modules needed, number of modules per string and the number of strings
- 25. • Lack of equipment's. • Long time shipping. PROBLEMS WE FACED
