Introduction to energy generation

Prior to the discovery of Faraday’s Laws of electromagnetic discussion, electrical power was available from batteries with limited voltage and current levels. Although complicated in construction, D.C. generators were developed first to generate power in bulk.

However, due to limitation of the D.C. machine to generate voltage beyond few hundred volts, it was not economical to transmit large amount of power over a long distance. For a given amount of power, the current magnitude (I = P/V), hence section of the copper conductor will be large.

Thus generation, transmission and distribution of D.C. power were restricted to area of few kilometer radius with no interconnections between generating plants. Therefore, area specific generating stations along with its distribution networks had to be used.

In later half of eighties, in nineteenth century, it was proposed to have a power system with 3-phase, 50 Hz A.C generation, transmission and distribution networks.

Once A.C. system was adopted, transmission of large power (MW) at higher transmission voltage become a reality by using transformers. Level of voltage could be changed virtually to any other desired level with transformers – which was hitherto impossible with D.C system.

    I have a 150 KVA generator. It suddenly developed a malfunction recently. When it is switched on, it runs for about 30 seconds and then goes off. It is electronically switched on or off.

    Dear EE Portal,

    Thanks for having such informative website.I am looking for quite long about Electricity metering sp[specifically define kwh meter, var and var hour meter and smart meter.

    If their is any book regarding metering please send me on [email protected]

    hello sir,

    Please clear my confusion. While calculating load currents for sizing the cables, which P.F.should be used?? Old or new after compensation..? and also i heard that reduced cable size depends on the type of compensation.i.e. global, sector or individual…please explain.

      Hello,

      If you are talking about XLPE cables, then the power factor to be selected as per the load type. If it is residential, then you can go to 0.8 or below ; if it is commercial/ industrial you have to go to 0.9 or unity (If full motor/ pump loads).
      You can select/ alter the PF as per the local authority approvals only.

      For Fire pumps, large motors & AC units(with motor) always consider starting current as 1.5 times the normal load as standard to size the MCCB/ Isolator rating & then select the cable size accordingly.
