Research Contributions

Research Contribution through Ph.D. Research by Self

Models Developed for Distribution System Components in the name of a€?Ko Modelsa€?:

Unit voltage regulation constant for a given circuit voltage, power factor and conductor size

Voltage Regulation in a Radial feeder in %

iii

Power Loss in a Radial Distribution feeder,

Where kV is the nominal voltage of the feeder in kilo Volts, P is the Peak Load of the feeder in kVA, M is the total moment in km-kVA, r is the resistance of the conductor of feeder per km in Ohms, LDF is the Load Distribution Factor and PLDF is the Power Loss Distribution Factor

iSubstation Feed Area

Where (pf) is the power factor of the load and nf is the number of feeders fed by the Substation.

When the feed area of the Substation is circular, then the Radius R of the Substation is,

Where z is the zig-zac factor of the main feeder given by L/R.

Nomograms, The following Nomograms are developed as Ready Reckoner for Distribution System Planning:

Voltage Regulation Chart
Feeder Power Loss Chart
Feeder Main Chart
Number of Feeders per Substation Chart
Conductor Gradation Chart for the Feeder Mains
Substation Feed Area Chart
Ready Reckoner for Irrigation Pump-set size selection
