Title: Controller for steam turbine
Inventor: TAKAHASHI NARIHARU
IPC: F01K23/10
Filed: 1986-03-12
Abstract: PURPOSE:To spread the operation range of a steam turbine and permit the high efficiency operation by installing a main steam controller for controlling a main steam valve by the control signal supplied from a judging device for setting the steam turbine within an allowable operation range. CONSTITUTION:A pressure transmitter 21a for detecting the steam pressure in the rear part 5 of the intermediate pressure step of a steam turbine and a flow rate transmitter 23a for detecting the steam flow rate of the steam turbine are provided. The allowable operation range in the case when the admission steam is inserted is previously set in a judging device 24a, which compares the pressure detection signal an the flow rate detection signal, and the deviation is obtained. When the deviation is not within the allowable operation range, the control signal for compulsorily setting the operation state of the steam turbine into the allowable operation range is outputted. A main steam controller 28a controls a main steam control valve 27 by the control signal supplied from the judging device 24a. Thus, the operation range of the steam turbine is spread and the high efficiency operation is permitted.

Abstract: PURPOSE:To provide possibility of driving either of the drive mechanisms selectively without particular operation for changing-over by furnishing a drive mechanism, which retracts when a drive nut in meshing with a feed screw part on the actuator shaft is rotated, and a drive mechanism to rotate this actuator shaft. CONSTITUTION:If motor 7 of No.1 drive mechanism 3 is rotated while NO.2 drive mechanism 11 is at a standstill, the torque is transmitted to a drive nut 4, which is thus put in rotation.
