| 摘要: |
| 为进一步改善多机系统的暂态稳定性,结合直接反馈线性化原理和最优控制理论推导出多机系统中励磁的分散控制规律。该控制策略是根据多机电力系统观测解耦状态空间得出,只需要当地信号实施控制,驱动子系统到达局部平衡点,就能使全系统达到稳定。仿真结果表明,该控制规律能够较好地提高多机电力系统的暂态稳定性。 |

| Abstract: |
| To improve transient stability of multi-machine power systems, this paper presents a control strategy of generator excitation based on the direct feedback linearization method of nonlinear systems and the optimal control theory of linear systems. Using an observation decoupled state space model of multi-machine power systems, the control rule is easy to be implemented because it needs only local information to drive the subsystems to reach their local equilibrium points, and then the total system is stable... |
