| Abstract: | Steam turbine control system may cause several low frequency oscillation events of the power grid, thereby, it is necessary to consider steam turbine control system model for analyzing low frequency oscillation. On the basis of analyzing constitution of the single-turbine unit and load control system, this paper provides mathematical models of coordination con- trol system and digital electro-hydraulic control system of the steam turbine. On the basis of analyzing valve structure, con- trol way and discharge characteristic, it provides steam turbine model considering of valve discharge characteristic. |
