The paper presents approximate model for determining the voltage stability margin. In the first part, Thevenin model and equations describing this model e.g. stability limit are presented. Influence of load and system impedance changes on variations of node voltage are shown. Second part consist description of approximate model determination methods. For the analysis, the 14-bus IEEE model have been chosen. Basing on this model the impact of configuration changes on the Thevenin parameters of considered receiving nodes have been analysed. At the end, the possibilities of use of approximate model for determining the voltage stability margin are described.
