Chaotic control of the interconnected p ower system based on the relay characteristic function

摘要: 电力系统中的混沌振荡对整个互联电网具有极大危害。本文利用Lyapunov指数、分岔图、相平面图和功率谱等分析一个简单互联电力系统的动力学行为，研究电力系统对电磁功率扰动幅值的敏感性。同时，提出一种基于继电特性函数的准滑动模态控制方法，对系统进行混沌振荡抑制，使系统快速平滑地到达控制目标。实验表明，该方法不仅能够缩短控制时间，减少因参数过大带来的系统冲击，而且对高频抖动也有很好的抑制作用，具有较强的鲁棒性。

Abstract: Chaotic oscillation in a power system is very harmful for the large-scale interconnected power grid. Here, the basic dynamic properties of the interconnected power system are investigated under the disturbance of electromagnetic power through the Lyapunov exponent spectrum, bifurcation diagram, phase plane, and power spectrum. The sensitivity to the disturbance of electromagnetic power is also studied. Meanwhile, from the sliding mode variable structure control and relay characteristic function, a new method to control the chaotic oscillation is presented, which can quickly and smoothly make the system reach the expected target. Simulation results show that the method can not only shorten the control time, but also reduce the possibility of the impulse response from the system, due to the large parameters. It can inhibit the high-frequency buffeting effectively and has strong robustness.
