基于两机扩展Heffron-Phillips模型的励磁系统调差系数对系统阻尼特性的影响
|
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。
Excitation system adjustment coefficient is an important parameter of excitation system control. Reasonable parameter setting is conducive to safe and stable system operation. In this paper, firstly, extended two-machine Heffron-Phillips model was derived. Based on this model, influence of excitation system adjustment coefficient of the two-machine system on system damping characteristics was studied. Through system eigenvalue analysis, concept of adjustment coefficient sensitivity was proposed to characterize damping and differential coefficient correlation adjustment, looking for damping and difference between key system parameters. For multi-machine excitation system adjusting aberration coefficient setting, this model has certain guiding significance.
