摘要
以特征值分析法研究广东电网的动态稳定特性,结果显示:广东电网机组参与南方互联电网阻尼比为5%～10%的区域振荡模式,主振荡频率为0.4202Hz,阻尼比为5.31%;广东电网内存在一个地区振荡模式,振荡频率为1.1Hz,阻尼比为2.18%。对广东电网系统发生的两次低频振荡事故进行分析,并提出广东电网系统运行的动态稳定预防措施及解决策略。
The eigenvalue analysis method is employed to research the dynamic stability characteristics of Guangdong Power Grid （GPG）. The result indicates that some GPG＇s gerenators participate in the area oscillation with damping rate of 5%-10% in the southern interconnected power grid. The main frequency of the oscillation is 0.420 2 Hz with a damping rate of 5.31%. There is a local oscillation in GPG, which has the frequency of 1.1 Hz with the damping rate of 2.18%. After analyzing two cases of low-frequency oscillation accidents, the paper presents preventation measures and solutions for the GPG dynamic stability.
