The paper concerns the problem of local voltage instability of the power system receiving node. There were presented bases of analysis of stability margin determination using Thevenin equivalent model. Basing on Thevenin model new method of stability margin calculation was developed. The method has been described in the article. Contrary to well known methods, presented algorithm does not use a derivates of measured parameters. The algorithm uses only the measured values of steady working points. The last part of paper contains an analysis of potential errors.
