Abstract
Energy is an important input for economic development of every country and electric power sector is an indispensable infrastructure in any economy. Quetta Electric Supply Company (QESCO) supplies electric power throughout Balochistan province of Pakistan except District Lasbela. Balochistan covers 43% of the geographic area of Pakistan but is considered to be the least power consuming province. The load is far away from the source and radially fed resulting in low voltage profiles and frequent blackout of the company grid network. Power flow studies have great significance in determining the best criteria for designing a power system and planning the future expansion of power system. This research focuses on reinforcement analysis of QESCO network using Power System Simulator for Engineering (PSS/E) by simulating load flow analysis model. The operation of the three available power sources has been studied for maximum performance of the grid network. Different scenarios have been analyzed and quantified by applying all the parameters and values of QESCO power system and inferences have been obtained on the basis of results generated by the PSS/E Software. The comparison study has been carried out for the three N-1(loss of one source) contingency situations for the available sources and best possible network topology for optimal operation of QESCO network is proposed.
