 ABSTRACT

In this paper, the analysis of faults under deregulated power system is emphasized Vis-a- Vis as it affects the power system parameters. The interactive power system analysis (IPSA) program is employed and taken in two parts, deregulated system under fault and fault under deregulated system. Faults that occur in any power system are the same whether the system is regulated or deregulated. The three phase fault is analyzed although it rarely occurs, others are line-to-line, line-to line-earth and line-to- earth faults, all known as unsymmetrical faults. From the simulation analysis, fault currents are higher and voltage drops on lines are reduced. However, in a deregulated power system, the responsibility for fault management and control is decentralized. Also deregulated are the various units, generation, transmission and distribution. The resultant effect is that the entire system is better equipped for real-time enhanced fault localization and isolation in the event of fault occurrence. And this gives rooms for investors to come in.

Keyword: symmetrical faults, unsymmetrical faults, open conductor faults. Failure of insulation, thermal failure.
