| 摘 要： | 汽轮机涉网模型的参数存在着不确定性,对于不同频率的电网扰动,同一参数的不确定性对该频段的影响不同。从频域的角度,在电力系统低频振荡的频段范围内,分析包括蒸汽容积时间常数,再热容积时间常数,回热器惯性时间常数,不等率,主蒸汽压力等的汽轮机涉网特性参数对电网稳定性的影响。

| Abstract: | The parameters of steam turbine model related to grid have some uncertainty. For different frequency power system disturbance,the uncertainty of the same parameter has different effect on the band. From the view of frequency domain analysis,in the range of the low frequency oscillation of power system,the influence of the steam turbine parameters related to the grid to the power system stability is analyzed. The parameters include the steam volume time constant,the reheat volume time constant,the regenerator inertia time constant,the diversity factor,the main steam pressure,and so on. |
