摘要:
该文研究了广义梯度系统的拓扑性质,应用微分拓扑学原理证明,广义梯度系统的完全稳定性与势能界面的有界性是等价的;广义梯度系统完全稳定当且仅当该系统既有渊点又有源点。在此基础上提出了一种检验广义梯度系统完全稳定性的方法。对一个三机系统、新英格兰系统和IEEE50机系统的仿真验证了上述结果的正确性。
Abstract:
Th is paper investigates topo log ical propert ies o f the genera l grad ient system, and demonstrates by results of d ifferent ia l topo logy that the boundedness o f the general gradient system is equ ivalent to the boundedness o f the potential energy boundary surface ( PEBS) . Moreover, a general grad ient system is bounded i,f and only if the system has both sink po int and source po in.t B ased on these resu lts, a feasible method is proposed to check the comp lete stability of the genera l g rad ien t system. The results are con firmed by simu lations on a 3-machine system, the N ew Eng land system and the IEEE50m ach ine test system.
