Power load flow analysis

Abstract

The main objective of this project is to analyse the electrical load flow pattern of the distribution network of Federal university of Technology Minna. To establish a load flow pattern that may be projected with the use of computer. The electrical network consists of six busbars, two distribution substations which contain 2x500KVA, 11/0.415KV step down transformers, located within the load centers of the university. Each busbar has an upriser armoured cables serving different section of the university. The values of the busbars and line parameters are calculated on a bases of llKV, 2x500 KVA (l.0MVA). In the electrical distribution network, there are no regulating or phase shift transformers and capacitor bank which can serve as voltage of control buses. Numerical computation of busbar voltage is based on gauss iterative techniques after a thorough comparison with Newton iterative technique. A computer program is written in Qbasic language for easy understanding. A flow chart is drawn from the solutions of the network equations
