【摘要】 论述了事故后电力系统的同步平衡与稳定平衡的区分。频率平衡是稳定平衡的特例。提供了在网络结构保持模型下求解事故后稳定平衡点 (也包含同步平衡点 )的电流型方法 ,从而提供了事故后结局分析的一种有效手段 ,为暂态稳定分析奠定了基础。同时较完整地解决了经典电力系统模型所存在的结构问题更多还原

【Abstract】 This paper presents the difference of synchronous equilibrium and stable equilibrium of post fault power system.The frequency equilibrium is a particular case of the stable equilibrium. The solution method of the stable equilibrium and thesynchronous equilibrium for network preserving model is also provided. A new algorithm to effectively perform resultinganalysis of the post fault system is proposed, which gives the foundation of the direct stability analysis of power system and atthe same time completely solves the structure problems existing in the classical models of power system.更多还原
