    摘 要:在PSCAD/EMTDC平臺構建同電廠和不同電廠兩機系統模型,結合測試信號法和Prony算法,分析了系統發生次同步諧振的可能性及可控串聯補償(TCSC)抑制同型和不同型兩機系統次同步振蕩的效果。仿真結果表明,采取新的基準容量下,同型兩機等值系統的電氣阻尼為原單機時候的兩倍左右;TCSC在抑制兩機不同型系統同步諧振(SSR)問題時,需要分別為不同發電機設計附加次同步阻尼控制器,且位于不同電廠的兩機軸系之間不存在明顯的扭振相互作用。
    關鍵詞:次同步諧振;可控串聯補償;測試信號法

    Abstract: The two machines system model, which is in the same power plant or in the different power plants, was established on PSCAD/EMTDC platform. Combined with the test signal method and Prony algorithm, this paper analyzed the possibility of system sub-synchronous oscillation and the effect of thyristor controlled series compensation (TCSC) inhibiting sub-synchronous oscillation of homotype and different type two machines system. Simulation result shows that in adoption of new bench mark capacity, the electrical damping of the same model of two machines equivalent system is about two times of the single machine system; in issue of TCSC inhibition of two machine different model system SSR, there was a need to design additional sub-synchronous damping controller for different generators, and there was no obvious torsional interaction between two machines shaft system in different electric power plants.
              Key words: subsynchronous oscillation; thyristor controlled series compensation; test signal method
