对东北–华北电网直流互联后，东北电网发电机组电力系统稳定器(power system stabilizer，PSS)参数的适用性进行研究。首先，研究互联系统联网方式对系统主导振荡模式及对发电机组励磁系统频率响应特性的影响，并结合实际互联系统进行深入分析，揭示互联系统联网方式对PSS参数需求影响的关系。在上述研究的基础上，从多个角度对东北电网现有的PSS配置和参数进行评估，评估结果表明：东北电网现有的PSS配置和参数可满足东北–华北电网直流背靠背联网方式下基本运行方式及重要检修方式的运行需求。

The influence of interconnection scheme with AC or DC link on the power grid dominant oscillation mode and the frequency response of generator excitation control system were studied. The impact on the power system stabilizer (PSS) parameters requirements was also researched. Based on the above study, the PSS applicability for the Northeast-China Power Grid was validated in theory. The dynamic stability of the Northeast-China Power Grid in typical operation schemes, as well as the PSS impact on power system stability, was analyzed. The results demonstrate that the PSS of the Northeast-China Power Grid can satisfy the operating requirements for the DC link interconnecting North-China Power System.
