摘　　要：通过在临界线路上加装补偿装置来控制线路有功功率,可以抑制系统功率振荡,其有效性取决于最佳线路的选择。以特征值灵敏度分析方法为基础,提出了一种利用阻尼灵敏度指标选取临界线路的方法,通过计算特征值相对于线路参数的灵敏度,得到线路参数在区域振荡模式下阻尼灵敏度指标;然后通过阻尼灵敏度指标来选取区域振荡中的临界线路,并利用阻尼灵敏度指标评价系统线路参数对电力系统小干扰稳定性的影响。最后,通过新英格兰16机系统算例分析证明了该方法的正确性和有效性。Setting complementary equipment in the inter-area of critical line （：an restrain regional power oscillation more effectively, the effectiveness depends on the choice of the best lines. Based on a method of eigenvalue sensitivity analysis characteristic value, the method to select critical line is put forward by damping sensitivity index through calculating eigenvalue related to circuit resistance sensitivily. Then using a damping sensitivity benchmarking to select critical line and criticize how the system line index influences on power system small-signal stability. Finally, analyzes the correctness and effectiveness of calculation method through New England 16 machine Test System.
