Abstract

Dans un cas où un calcul de point d’équilibre stable n’est pas calculable par un procédé de Newton, un facteur d’amortissement d’un générateur d’équation différentielle de système mécanique, compris dans une équation algébrique différentielle non linéaire d’un système de puissance, est fixé pour être plus grand qu’une valeur effective du générateur du système de puissance. En appliquant une simulation pseudo-transitoire à l’équation algébrique différentielle non linéaire du système de puissance comprenant une équation différentielle de système mécanique du générateur, spécifiant le facteur d’amortissement, une norme d’équation de système mécanique est trouvée. Si cette norme satisfait une condition prédéterminée, les valeurs variables du système de puissance à un moment où la norme est trouvée sont fixées comme valeurs initiales de l’équation algébrique différentielle non linéaire du système de puissance. Un point d’équilibre stable est déterminé en appliquant le procédé de Newton à l’équation algébrique différentielle non linéaire dans laquelle les valeurs initiales sont fixées.
