【摘要】：励磁系统调差系数是励磁系统控制的重要参数,合理的参数整定有利于系统的安全稳定运行。首先推导了两机扩展Heffron-Phillips模型,并在此模型的基础上研究了两机系统下励磁系统调差系数对系统阻尼特性的影响。通过对系统进行特征值分析,提出调差灵敏度的概念来表征阻尼与调差系数的相关关系,寻找影响阻尼与调差相关性的关键系统参数,对多机系统励磁系统调差系数的整定配置有一定指导意义。
[Abstract]:The adjustment coefficient of excitation system is an important parameter of excitation system control, and reasonable parameter setting is beneficial to the safe and stable operation of the system. In this paper, a two-machine extended Heffron-Phillips model is first derived, and based on this model, the influence of the difference adjustment coefficient of the excitation system on the damping characteristics of the system is studied. By analyzing the eigenvalue of the system, the concept of sensitivity of adjustment difference is proposed to characterize the correlation between damping and adjustment coefficient, and to find the key system parameters that affect the correlation between damping and adjustment. It has certain guiding significance for setting up the adjustment coefficient of excitation system of multi-machine system.
