【摘要】 PSS作为抑制低频振荡的有效措施,其参数的好坏直接影响到其抑制低频振荡的效果。介绍PSS参数的两点整定方法,并以实际电网中某机组的PSS现场试验数据为依据,应用两点整定法评估现有PSS参数对低频振荡的抑制效果。结果表明,应用两点整定法得到的PSS参数在相位补偿和提高低频振荡阻尼这两方面都有很好效果,可以用于PSS参数评估并能对低频振荡有较好的抑制效果。更多还原

【Abstract】 As the effective measures to inhibit low-frequency oscillations, PSS parameters can directly affect the inhibitory effect to low-frequency oscillations.The two-point method of PSS parameter setting is introduced and used to evaluate the existing PSS parameters based on field test data.The results shows that the PSS parameters setting according to two-points method have very good results in both the phase compensation and the improvement the low frequency oscillation damping .This method can be used to evaluate PSS parameters and have a better inhibitory effect to low-frequency oscillations.更多还原
