摘要
Abstract
Excitation system adjustment coefficient is an importantparameter 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 coefficientsensitivity 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.关键词
