CONTINGENCY ANALYSIS OF POWER SYSTEM NETWORKS

In this modern power system, planning and construction of the system with outage
minimization as a major design criterion is becoming more important. However,
even with the best possible construction and operating practices, outages still can
occur. Several techniques have been developed to analyze the status of the system
after the real outage occurs. This project presents an alternative way of conducting
power flow analysis in determining the new bus voltages and line currents during
outage occurrence. The algorithms have been accommodated in one complete
program making it an effective tool for contingency analysis. The program has been
tested on an IEEE bus test case and the remarkable results obtained in terms of its
reduced computation time and accuracy showed that this technique could be
implemented, particularly when involving practical work with a lot of calculations.
