A developed algorithm for optimal placement and sizing of thyristor controlled series capacitors (TCSC’s) for enhancing the static security of power system and minimizing the overall power system loss is presented in this paper. A procedure to determine the optimal locations and sizes of the thyristor controlled series capacitors is illustrated and presented. The locations are determined by evaluating contingency sensitivity index (CSI) for a given power system branch for a given number of contingencies. Optimal sizes of TCSC’s are determined by the optimization technique of simulated annealing (SA), where TCSC’s settings are chosen to minimize the overall power system …

This paper presents an algorithm to determine the fault type on transmission line based on wavelet transformation analysis. The algorithm is developed by analyzing the three phase currents (Ia, Ib and Ic) using Wavelet Transformation, and then start to study the faulted phase(s) at different location (each 5% of the transmission line (TL) length). Fault simulation is carried out by EMTDC/PSCAD program. Two seconds window of waveform covering pre-fault and post-fault is used. The discrete wavelet transforms (DWTs) are used for data pre-processing. Four types of mother wavelet are used for signal processing to identify the effective wavelet family that …
