【摘要】 对于大扰动下在后续摆动中失去稳定或者呈现出多群的失稳模式的电力系统 ,其稳定性的定量研究非常困难 ,在对支路势能方法的模型以及实现方法进行论述的基础上 ,对该方法在多摆多群的稳定性定量分析进行了研究 ,多机电力系统的仿真结果表明该方法可定量研究多群多摆的暂稳问题。更多还原

【Abstract】 It is very difficult to study the multi-swing&multi-group transient stability of power system.To the large disturbance,In the paper the model and development of Branch Transient Potential Energy Method is introduced,and its application to assessing multi-swing&multi-group transient stability of power system is studied.The simulation of the multi-machine power system show the validation of Branch Transient Potential Energy Method in multi-swing&multi-group transient stability assessment.更多还原
