ELECTRICAL POWER GENERATION FROM RAILWAY SYSTEM

The world has already had its share of its energy resources. Energy crisis is one of the major problems in India. In this project “ELECTRICAL POWER GENERATION FROM RAILWAY SYSTEM “we are here to provide a solution for those energy crises. The number of vehicles passing over the track is increasing day by day. There is possibility of tapping the energy and generating power by making the railway track as a power generation unit.

As the vehicle passes over the railway track the load acted upon the track or plant setup is there by transmitted to rack, pinion and chain sprocket arrangements, were the reciprocating motion of the track is converted into rotary motion. Then this rotatory motion is then fed on to the gear drives which multiplies its speed. This speed which is sufficient to rotate the rotor of a generator is fed into the generator were an electro motive force is produced.

The generated power can be used for the lamps near the railway station or connected to grid and this will be a great boon for the rural villages too. e.g., The mass of a vehicle moving over the track =57.0 to 69.9 kg/m (assumption ) and Height of spring to be 20cm, then Power developed for 1 vehicle passing over the spring arrangement for one minute= 4.0875 watts and The Power developed for 60minutes(1hr)=245.25watts.

For railway in India has a number of tracks .By just placing a unit like the “Power Generation Unit from railway track ”, so much of energy can be tapped. The utilization of energy is an indication of the growth of a nation. One might conclude that to be materially rich and prosperous, a nation should concentrate more on conservation and production of Eco friendly power.

Electrical Power Generation System Using Railway Track

An electrical power generation system comprises a variable capacitor and a power source and it can generate electric power via movements of the rail. The variable capacitor is charged by the prime mover that effectively multiplies the priming energy of the power source by extracting energy from the passing vehicle. due to change in capacitance than from the power source itself, large amount of electrical energy is produced.

DESCRIPTION:
The system includes a power source, such as a power generation device or an external powersource. The power co-generation system includes first and second electrical capacitance portions that are electrically coupled to the power source and that are configured to carry positive and negative charges, respectively.

The power co-generation system further includes a biasing device that is configured to separate the first and second capacitance portions with respect to one another. Thus, by varying the distance between the capacitance portions in response to a vehicle on the rail, the capacitance portions cooperate to act as a variable capacitor that facilitates the co-generation of power with respect to the system. That is to say, the mechanical energy of the biasing device is converted into electrical energy for the system.

In accordance with another exemplary aspect of the present technique, a method of co-generating power via a vehicle traveling on a rail is provided. The method includes the act of driving first and second capacitor plates with respect to one another in response to the vehicle that is traveling on the rail. The method also includes the act of charging the first and second capacitor plates via a power source, such as a power generation device or an external power source.

The method further includes biasing the first and second plates apart from one another, thereby displacing the plates with respect to one another. This displacement changes the electrical capacitance between the first and second plates and, resultantly, increases the electric potential between the first and second plates. In turn, this displacement of the first and second plates facilitates the co-generation of electrical energy from the kinetic and potential energy of the vehicle on the rail.
