一类电力系统分岔的仿真研究
Simulation Research on Bifurcation in a Type of Power Systems
摘要
Abstract
In order to study the bifurcation in a classical two order nonlinear power system,the paper intro-duces the basic concept of bifurcation types in power system,and solves the condition of saddle-node bifurcation of the system.The paper makes a numerical simulation research on bifurcation of the power system by MATLAB.The paper gives different state response curves in terms of different parameters.The simulation analysis verifies the correctness of the numerical calculation results,and works out the influence of parametric variation.Simulation results show that the parameters variation of the system may cause the state bifurcations.The system becomes more complex with the growth of parameter E and parameter V,leading to chaos.However,the change of mechan-ical input power Pm can cause more complex dynamical behavior and produce periodic bifurcation and chaos phe-nomenon.Therefore,we should pay attention to the control of this parameter in operating power systems.关键词
