摘要:
建立带电磁功率扰动和负荷扰动的互联电力系统模型,在双重扰动频率呈现不同数值关系的情况下,通过绘制分岔图、Lyapunov指数图、相平面图和功率谱,深入分析在扰动幅值变化时系统的动力学特性,研究系统对扰动幅值的敏感性. 对比系统在不同扰动干扰下动力学行为的复杂程度,针对系统功角失稳问题,准确划分在失稳场景下扰动参数的数值范围,为电力系统稳定运行提供可靠理论依据.
Abstract:
An interconnected power system model with electromagnetic power disturbance and load disturbance is established. Considering double disturbance with different frequency,the paper analyzes the dynamic characteristics of the system in depth when the disturbance amplitude is changed. Through the bifurcation diagram,the Lyapunov exponent spectra,the phase-plane diagram and the power spectrum,sensitivity of the system to the amplitude of disturbance is discussed. When pointing at the problem of power angle instability in the system,the numerical range of the disturbance parameters is accurately divided in the unstable scene,and numerical simulations for the dynamic behavior of the system are performed under different disturbances. At last,a reliable theoretical basis for the stable operation of the power system is provided.
