摘要
该文将常规最优励磁控制方式与PID励磁控制和PSS的特点相结合,提出了使用系统部分可测量及其微分量以构成一组状态反馈量的优化励磁控制的设计方法,简化了控制器的测量通道。文中建立了该控制系统的动态方程,计算了输电系统在该控制方式下的静态稳定性、暂态稳定性和动态特性,并与对应的常规最优励磁控制方式进行了比较。结果表明,所提出的简化测量通道优化励磁控制方式较常规最优励磁控制方式的性能更为优越,并由于简化了测量通道,实现起来更加容易。
Combining conventional optimal excitation control with the characteristics of PID excitation regulator and power system stabilizer, this paper presents a new design method for optimal excitation control. In the design method, the partial measurable variables of transmission system and their differential variables compose a set of state feedback variables, so the measurement channels of the excitation control are simplified. The math model of the control system is established. The static stability, transient stability and dynamic characteristics of the control system are calculated. The results show that the control is superior to the conventional optimal excitation control in capability. In addition, as the control's measurement channels are simplified, it can be taken into practice in engineering more easily.
