Procedimiento para la regulación de un incremento breve de potencia de una turbina de vapor |
摘要 |
A method is provided for controlling a short-term increase in power in a steam turbine including a fossil-fired steam generator having a flow path through which a flow medium flows. The method involves tapping off the flow medium from the flow path in a pressure stage and injecting it into the flow path on the flow-medium side upstream of a super heater heating surface of the respective pressure stage. A first characteristic value is used as a controlled variable for the amount of injected flow medium. The first characteristic value is characteristic of the deviation between the outlet temperature of a final super heater heating surface of the respective pressure stage on the flow medium side and a predetermined nominal temperature value. The nominal temperature value is reduced and, for the duration of the reduction in the nominal temperature value, the characteristic value is temporarily increased over-proportionately to the deviation. |
