Although the measures such as the simulation method with detailed generator model in which the dynamic behavior of exciting system is taken into account and installing power system stabilizers in main generators of Northeast Power Grid were adopted, it was still unable to effectively verify the reasonableness of parameter setting of PSS as well as its integrated matching result, and there was not enough scientific foundation for the selection of power grid model, especially load models. Moreover, it was hard to make accurate quantitative analysis, even though the qualitative analysis, on the close extent of selected models to actual operation of power grid.

虽然采取了计及励磁系统动态行为的详细发电机模型的仿真方法、在东北电网重要发电机组上加装电力系统稳定器(power system stabilizer，PSS)等措施，但PSS参数整定的合理性及整体匹配效果无法得到有效验证，选择电力系统模型尤其是负荷模型还缺乏足够科学依据，对所选模型与电网运行实际的贴近程度也很难做出准确的定量甚至定性的分析。

The thesis shows that the contradiction analysis method and the system analysis method are not inconsistent but consistent; that the contradiction analysis method is the core and system analysis method is its supplement and expandedness.
