Fault Analysis Of 132KV Transmission Grid Power System For Improved Stability Using 4TH Order Runge Kutta Numerical Technique
Subject area: Science,Engineering and Technology · Area of research: Electrical Engineering(Power System)
Abstract
System collapse or cascaded outage within a power system is very hazardous to the power system equipment and operation. This work investigates the transient response of the generators in 132KV grid network of Afam power generating station to Port Harcourt Main (Zone 2) injection substation using 4th order Runge Kutta numerical techniques to determine the critical clearing angle (CCA), then critical clearing time. When Electrical Transient Analysis Program (ETAP 19.1) is deployed with circuit breaker and relay time setting of (0.00,0.02, 0.04, 0.06, 0.08, 0.10, 0.12, 0.14), the results obtained indicate that the protective device must be coordinated properly to quickly clear a 3-phase balanced fault at any bus, in order to enhance stability margin to avoid system collapse. The results obtained shows that 4th order Runge Kutta Numerical Technique is stable, accurate, has a response time of 0.02s, lower percentage error of -51% and it gives a significant power transfer capability of network from 0pu to 3.7870pu after fault has been cleared.
Keywords
