PROCEDURE FOR THE REGULATION OF A STEAM TURBINE WITH STEAM EXTRACTION, REGULATION DEVICE FOR A STEAM TURBINE WITH STEAM EXTRACTION AND STEAM TURBINE WITH STEAM EXTRACTION.

摘要

Procedure for the regulation of a steam turbine (1), in which a feed (9, 11, 13) of steam is regulated through a feed valve (15, 17, 19) and an extraction (21, 23 ) of steam through an extraction valve (25, 27), - in which a first regulator (36A) or a second regulator (36B), depending on magnitudes (R1A, R2A; R1B, R2B) regulating fed to this in each case, it emits a first regulation signal (YEA; YEB) and a second regulation signal (YSA; YSB) to a regulation structure (37A; 37B), - in which, in the case of a change specific to the task between the regulators (36A, 36B) always using the same regulation structure (37) with a set (50) of parameters divided into subgroups (51, 53), with a first parameter (AV1, AV2) and a Second parameter (BV1, BV2) in each case within each subgroup (51, 53), combine the result of a conversion of the first signal (YE) of regu connection with the second parameter (BV1, BV2) and the result of a conversion of the second regulation signal (YS) with the first parameter (AV1, AV2) and - in which a first subgroup (51) determines a first adjustment signal (S1) fed to the supply valve (15, 17, 19) and, with a second subgroup (53), a second adjustment signal (S2) fed to the extraction valve (25, 27).
