METHOD AND DEVICE FOR CONTROLLING A STEAM POWER PLANT

摘要

The invention relates to a method comprising the following steps: providing (34) a first signal (Sl) showing a reduction of the current power level (PEL) of the generator (12), generating (36) a second signal (KU) showing a short circuit interruption as a function of the first signal (Sl), resetting (38) the second signal (KU) after a predetermined time period (TKU) and blocking (38) the second signal for a predetermined period of time (TSPKU), stopping and subsequently starting (40) the turbine (14) as a function of the second signal (KU), generating (42) a third signal (LAW) showing a load rejection as a function of the first signal (Sl), and permanently stopping (44) the turbine (14) as a function of the third signal (LAW).
