| 摘 要： | 利用反步法设计了多机电力系统中的非线性鲁棒自适应励磁控制方案,控制目标是调节发电机功角和频率至稳态运行点的极小领域,并使闭环系统对发电机阻尼系数和电抗参数的不确定性具有自适应能力,且对模型误差和外部有界干扰具备鲁棒性,同时保证各控制器是分散化和本地化的。采用4机系统进行的数字仿真结果表明,实施此方案能有效地提高发电机的功角稳定性。 |

| Abstract: | This paper presents a nonlinear robust adaptive excitation control design procedure for multi machine power systems using back-stepping method. The control objective is to drive machine power angle and frequency to the steady-state operation point, and guarantee that the close-loop system is adaptive to the uncertainties of generator damping coefficient and d-axis reactance, and robust to model errors or bounded disturbances. In the same time, it should guarantee the localized and decentralized features of each controller. The digital simulation results based on a 4-machine power system have showed that the proposed strategy can greatly improve generator angle stability. |
| Keywords: | power system transient stability excitation control robust adaptive control back-stepping |
