At present scenario, in Indian Power System shunt capacitor banks have been installed at 33 kV voltage level at EHV substations to compensate load reactive power demand. Capacity of installed shunt capacitors are not matching with load reactive power demand which results excessive reactive power flow on lines and transformers. Poor power factor of lines and transformers, results higher transmission...
Power system extends from generation to large distance load end, losses will be there in transmission & distribution section. This paper discusses the effect of capacitor placement, optimum voltage setting of generators, optimum dispatch of active power and SVC placement on power system losses and other technical parameters. IEEE 14 Bus system has been designed as test model in Mipower software...
In present power system structure, large capacity thermal power plants have been installed at remote locations from load centers. The power from generation to load centers is transmitted through long EHV transmission lines & number of EHV substations of various voltage levels are required for step down the power. This extended EHV corridor have acquired large chunk of land & raised the issues...
Large number of substations have been upgraded to higher voltage level by loop in loop out of existing transmission lines to meet the increasing load demand. Therefore; large number of loops of different voltage levels has been created between substations. Transformers of different MVA ratings; percentage impedance and tap ratios have been installed at the substations. Presently there is no coordination...
