Transient Stability Assessment and Enhancement in Power System
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 9
Abstract
Power system is subjected to sudden changes in load levels. Stability is an important concept which determines the stable operation of power system. For the improvement of transient stability the general methods adopted are fast acting exciters, circuit breakers and reduction in system transfer reactance. The modern trend is to employ FACTS devices in the existing system for effective utilization of existing transmission resources. The critical clearing time is a measure to assess transient instability. Using PSAT, the critical clearing time (CCT) corresponding to various faults are calculated. The most critical faults were identified using this calculation. The CCT for the critical faults were found to change with change in operating point. The CCT values are predicted using Artificial Neural Network (ANN) to study the training effects of ANN. TCSC is selected as the FACTS device for transient stability enhancement. Particle Swarm Optimization method is used to find the optimal position of TCSC using the objective function real power loss minimization. The result shows that the technique effectively increases the transient stability of the system
