基于Matlab/simulink电力系统暂态稳定性分析仿真模型,不同切除时间对两相接地故障的影响(Matlab/simulink power system transient stability analysis of the simulation model)

说明：  快速谱峭度方法，选择信号峭度最大的频段进行滤波，对滤波好信号进行包络谱分析(Fast spectral kurtosis method, select the frequency band with the maximum signal kurtosis for filtering, and analyze the envelope spectrum of the filtered signal)

这是较好的Matlab源代码，希望此代码能对大家有所帮助。(This is a better Matlab source code, I hope this code can be helpful to everyone.)

This simulink model simulates the damped driven pendulum, showing it s chaotic motion. theta = angle of pendulum omega = (d/dt)theta = angular velocity Gamma(t) = gcos(phi) = Force omega_d = (d/dt) phi Gamma(t) = (d/dt)omega + omega/Q + sin(theta) Play with the initial conditions (omega_0, theta_0, phi_0 = omega(t=0), theta(t=0), phi(t=0)) and the system parameters (g, Q, omega_d) and the solver parameters/method. Chaos can be seen for Q=2, omega_d=w/3. The program outputs to Matlab time, theta(time) & omega(time). Plot the phase space via: plot(mod(theta+pi, 2*pi)-pi, omega, . ) Plot the Poincare sections using: t_P = (0:2*pi/omega_d:max(time)) plot(mod(spline(time, theta+pi, t_P), 2*pi)-pi, spline(time, omega, t_P), . ) System is described in: "Fractal basin boundaries and intermittency in the driven damped pendulum" E.
