5、order to deal with commuters to have reliable mobile telecommunication networks that they across the railway, We need wind power .solar power and water power to design hybrid renewable power systems.IntroduceAccording to research. We need wind. and equipment are 1KW Wind Turbine Generator Controller

6、 Tower mountingsolar: equipment includes high quality solar modules with 25 year warranty. And solar module mounting frames in addition LCD display with data logging maximum power point tracking solar booster solar module tracking frames.ScopeDepending on the new railway lines, And the hybrid renewa

7、ble power systems lives near here.The problem Difficult to control the climate and exhaust noise.Conventional hydro requires the flooding of lacking large areas of land, and battery cost and inverter cost. According to research, we can learn that Remote districts use electricity the load not to be a

8、ll big generally, therefore is uneconomical with the electrical network power transmission, directly generates electricity commonly used in the locality uses the diesel electric engine. But the diesel oil storage and transport too is high to the remote districts cost, therefore the diesel electric e

9、ngine only can take one kind of short-time emergency power supply, Must solve the long-term stability reliable power supply problem, only can rely on local the natural energy source. The solar energy gentle breeze can be most universal and the water power, Solar power Accord to solar data, we use so

10、lar power in summer from eleven oclock to fourteen every day and winter time is from eleven oclock to thirteen In order to good use of wind power, We learn that sometimes the wind speed is the highest in Autumn, on the contrary, the wind have the least spring The water system transmits power from th

11、e turbine shaft to the generator shaft or the shaft powering another device, and as the voltage is very high wiring can be kept to a minimum and the wiring can be run over a longer distance due to the higher voltage 4.0 DESIGN OF HYBRID POWER SYSTEM 4.1 Output Requirements for the Power SystemThe ma

12、ximum total energy requirements by the telecommunication transmitter site is 1kWhr / day.Typically most telecommunictions infrastructure works on 48VDCThe maximum current for thie output equipment would be under 10 AmpsThe design will incorporate storage of energy for 3 days in the case for lack of

13、generation from all of the inputs4.1.1 Block diagram for the hybrid design4.1.2 Battery storage size requiredTo calculate the size of the battery bank required we converted the toatal daily energy consumption in Watt-hours to Amp-hours. Then multiply this by the required number of days storage plus

17、or 5 hours per day(5/24 hours = 0.2days)The amount of energy available for solar power depends upon the area (m2) of the PV arraySo at 40Wh/m2 for 5 hours per dayFor the solar PV array to provide all of the energy for one day (1kWh/day) will require 50 m2 of solar panels (about half a size of a hous

19、lculated using the following equation Co=0.3 for a 3 blade turbine A = area of bladesv= average velocity of the windrair = 1.21 kg/m3= (Air density)For a wind generator in 10 m/s wind (3 hours per day) to produce 1kWh/day the Area of the blades needs to be as followsRadius / diameter of blade A 7.5

20、m diameter blade wind turbine (approximately 7.5kW) can supply enough energy to the system for one day operation4.2.3 Converting available hydro power into kWhr/dayQ = flow rate L/sG = gravity 9.81 (m/s)H is usable head (m)A the stream flow of 300L/min is available 24 hours a day except in the winte
