A computer program to analysis of unsymmetrical fFault in electric power systems by visual basic

Abstract EN

This work is concerned with a program to model an electrical power network ad simulate the factors which have a bearing on the fault in the network .These factors are 1- The amount of loading at the instant that the fault occurs.

2- Site up the fault relative to the generation station.

3- The type of fault on hand.

4- Earthing.

5- Current Limiting Reactance.

The program tries to connect its technological which depends on one step at a-time method in formulating impedance matrix for ZBas and symmetrical component method in analysis unstable systems for its training activities.
