Identificação de ilhamento elétrico em redes de transmissão de energia

Abstract

The real-time operation of a power electric system (SEP) is an extremely complex task, and therefore requires several functions analysis and control of the network. Thus, interruption of the energy supply and the formation of islands in electrical systems transmission is a crucial point for analysis system reliability. Consequently, the detection and correct identification the "islanding" electrical must be performed more fast possible. In this context, occurs the islanding electrical when transmission network subsets are electrically isolated from the interconnected power system. Given the importance this theme, the goal this conclusion work is implement in computer an algorithm able to detect and identify islanding electrical in transmission of networks, and moreover, to identify (Lines) critical branches. The differential of this work is the possibility of identification of critical branches to connected systems or not, through the addition of pseudo-information critical. To verify the effectiveness of algorithm, are used simple electrical systems (of dimension reduced) and systems well known IEEE (Institute of Electrical and Electronics Engineers): 14- bus system and 30 bus.
