This master thesis proposes a method for calculating Networks Equivalent for monitoring power system Voltage Stability in real time operation called Least-Squares & Weighted Method. Among its innovative characteristics, it can be mentioned the specific formulation developed to consider data provided by the Synchronized Phasor Measurement Systems in order to calculate the parameters. The use of network equivalent is fundamental to evaluate the risk of voltage instability in real time as it allows preventive measures to be taken to avoid critical operative situations. The text includes the studies carried out regarding equivalent concepts and also the analysis of a sequence of different formulations investigated in order to obtain the most suitable parameters. Additionally, practical results are presented, concerning the application of the proposed method in the voltage stability monitoring of buses of the Brazilian Interconnected National System.
