    摘 要:介紹了一起由于電廠一次調頻存在問題導致電網出現振蕩的振蕩擾動源定位及分析案例。通過PSASP仿真程序判斷振蕩的類型,利用支路能量割集法和基于WAMS的機組機械功率與電氣功率波動相位關系法對擾動源進行精準定位,進一步分析研究實現機組控制系統級振蕩源的定位。經實例證明,對電力系統分析定位類似事故提供了依據及方法。
    關鍵詞:一次調頻;低頻振蕩;強迫功率振蕩;振蕩源定位;能量割集法;調速系統

    Abstract:Introduction was made to a case of location and analysis of low frequency oscillation source which caused by the primary frequency compensation problem of power station. PSASP simulation programs were used to judge the oscillation types and to extractly locate the oscillation sources by the subcircuit energy cutset and the phase relationship between mechanical power and electric power based on WAMS. This paper further analyzed the location of the oscillation source of unit control system and the system realized the localization. Actual examples show that this method has great guiding significance for the power system to solve similar accidents.
    Key words: primary frequency regulation; low frequency oscillation; forced power oscillation; location of oscillation source; energy cutset method; speed control system
