| 摘要: |
| 对于非线性系统的同步发电机而言，当它偏离系统工作点或系统发生较大扰动时，如果仍然采用基于PID技术的电力系统稳定器，就会出现误差。为此，可以将其用基于非线性最优控制技术的励磁调节器代替。但是，非线性最优控制调节器存在着对电压控制能力较弱的缺点。提出了一种能够将非线性最优励磁调节器和PID技术的电力系统稳定器有机结合的新型励磁调节器的设计原理，即把PID控制能在工作点有效控制和非线性最优控制能够精确描述同步发电机运行状态的优点结合起来，从而对发电机进行有效的控制。仿真验证表明：该方法是可行的。 |

| Abstract: |
| When the generator(nonlinear system)deviates from its working point or when th e in-terference occurs in power system,errors come forth in the control of PID-technique-based PSS(Power System Stabilizer).NOEC(Nonlinear Optimal Excitation Controller)could be used in stead,but it is weak in voltage control.A design principle for the effective control of generator is pre-sented,which combines the PID-based PSS for working point control and the NOEC for accurate ope-rating condition description of generator.The simulative test verifies its validity. |
