| 摘要: |
| 建立了先进静止无功发生器（ASVG）与发电机励磁的五阶非线性状态空间数学模型，并采用多指标非线性控制（MNC）方法，设计该系统的协调控制器。最后仿真表明：该控制器既能有效地消除机械功率扰动下的机端电压偏差，又能使转速和电磁功率准确地追踪其给定值，保证电力系统的电能质量，还能适当地使功角增大，从而提高电力系统的稳定性。与线性最优控制（LOC）方法相比，MNC方法能更好地兼顾各状态的动、静态性能。

| Abstract: |
| 5th-order nonlinear state-space model is established for ASVG（Advanced Static Var Generator） and generator excitation system and the MNC（Multi-index Nonlinear Control） method is applied to design its coordination controller. Simulative results demonstrate that，the controller eliminates effectively the terminal voltage deviation when the mechanical power disturbs，makes the electromagnetic power and rotator speed accurately tracing their references to enhance power quality，and increases properly the power angle to improve power system stability. Compared with LOC（Linear Optimal Control） method，MNC method coordinates more effectively the dynamic and steady-state performances. |
