- step valve charged with steam
- step valve is then connected with the steam valve in step 4 of the invention Proceedings set.
- the invention comprises at least the steam turbine of the steam power plant two actuators for supplying steam to the turbine.
- step 4 of the method according to the invention the limit steam pressure setpoint by setting both Valves accomplished, so that better control behavior the steam turbine with regard to the limit steam pressure setpoint to be set compared to setting just one valve is achieved.
- a mathematical calculation can be carried out in a computer Model stored at least the steam-carrying component be, by means of which from the quantities measured in step 1 of the internal pressure, the internal and the external temperature the reference stress in the material (material) of the steam-carrying Component and its temporal course is calculated, which results from the pressure load, the temperature difference and possibly the actual spatial distribution of the mechanical stress in the material of the steam-carrying component.
- a simulation can, for example, by means of a digital process can be realized, the aforementioned Sizes read in in a time step process and are processed.
- the limit steam pressure setpoint can be determined, which is usually a turbine controller is supplied according to a control algorithm that adjusts the turbine valve (s).
- Limit steam pressure setpoint and its course over time are determined be, for example, in the simulation calculation based on the measured internal pressure of the steam-carrying Component this current value of the internal pressure gradually is purely mathematically increased until the resultant (initially theoretical) reference stress the value of the material limit stress reached or at least comes close. The way The determined limit steam pressure setpoint can then be set so that no damage to the steam-carrying component must be feared.
- the inside temperature can e.g. by direct measurement using one sensor or indirectly by deriving from another physical quantities (e.g. boiling state and pressure of the filling medium the steam-carrying component).
- another physical quantities e.g. boiling state and pressure of the filling medium the steam-carrying component.
