单参数电力系统亚临界Hopf分岔控制

Subcritical Hopf Bifurcation Control of Power System with Single Parameter

考虑单参数电力系统的Hopf分岔控制问题.利用设计的二次非线性控制器,将具有潜在威胁的亚临界Hopf分岔控制为超临界Hopf分岔,并以典型的双机三节点电力系统为例,验证了所设计控制器的有效性.

We investigated the Hopf bifurcation control of power system with single parameter.The potential threat subcritical Hopf bifurcation was transformed into supercritical one by designing effective quadratic nonlinear controller.Example shows that the designed controller is valid.
