基于兩機(jī)擴(kuò)展Heffron-Phillips模型的勵(lì)磁系統(tǒng)調(diào)差系數(shù)對(duì)系統(tǒng)阻尼特性的影響
[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.
