Моніторинг запасів статичної стійкості енергосистеми на базі вимірів векторів напруги

Abstract

The questions of construction and application of polynomial models (PM) for classification of power system operational conditions in depending on steady-state stability margins are considered. The measurements of voltage phasors are used as input data to PM. A comparison of PM and artificial neural networks by use a criterion of classification errors was realized.
