【摘要】 在认真研究了发电机励磁系统数学模型后,明确了机械功率是励磁系统的一个确定型(非随机的)扰动这一物理事实。指出过去在设计励磁调节器时,所做的发电机调速器不动作这一假设是不妥当的。据此提出了发电机励磁调节器的抗扰设计方案。即在通常的最优励磁调节器中引入一个伺服补偿器,该伺服补偿器实质是引入了发电机端电压偏差的积分反馈。数字仿真表明该设计方案有效地解决了过去设计的最优励磁调节器所存在的静态性能较差的问题,相应所设计的抗扰励磁调节器能真正做到维持发电机端电压在给定值上运行,且有良好的功角特性。更多还原

【Abstract】 After having seriously studied the mathematical model of generator excitation control system , the author in this paper defines a physical phenomenon that the mechanical power of the turbine is a deterministic perturbation to the generator excitation control system. An anti-disturbance design plan is proposed in this paper. The proposed anti-disturbance optimal excitation regulator can provide a better steady -state performance and can maintain the generator terminal voltage in all stable operation regions.更多还原
