【摘要】 提出了一种基于同调矩阵 Epsilon分解的发电机同调识别新方法。为了扩大基于 Epsilon分解的发电机同调识别算法的应用范围 ,并减小其计算量 ,文中对该方法进行了详细的分析与推导 ,得出反映发电机同调性的指标 ,并由此形成同调矩阵 ,对该矩阵进行一次 Epsilon分解即可识别同调机群。该方法原理简单、计算量小、应用范围广。对新英格兰 39节点系统的仿真计算验证了该方法的有效性。更多还原

【Abstract】 Based on Epsilon decom position of the coherent m atrix,this paper proposes a new method for identifying coherent generators.In order to enlarge the application field of coherency recognition m ethod based on Epsilon decomposition and simplify its com putation,this paper analyzes the computing procedure thoroughly,and obtains the primary indices for coherency recognition,thus form s the coherent m atrix.The coherent generators are known by Epsilon decom position of the coherent m atrix once.The new m ethod is theoretically simple and needs little extra com puting effort.It can be applied in many fields of power system analysis.Testresults on New England39- Bus System are presented to evaluate the effectiveness of the new method.更多还原
