| Abstract: | The Siemens 900 MW steam turbine adopts the Simadynd controller and the control instructions for the governing valve are created through minimal selection among the outputs of the load/rotating speed controller, main steam pressure controller, limiting device for turbine starting, exhaust steam temperature controller and the pressure controller for the blades in high-pressure cylinder. The control characteristic of the Simadynd controller is that it adopts the controlling methods of proportional bypass and switching control mode via minimal selection. |
