Abstract

PURPOSE: To reduce defects in controlling a turbine, by confirming the operation of a detector and a driving circuit for a bypass valve for a main steam stop valve before starting a turbine.
CONSTITUTION: When a diagnosis starting instruction is applied through a switch 1, a driver B for a bypass valve MSV-BV for a main steam stop valve is actuated through an output processing unit 2 to open the bypass valve 4. At the same time, a timer T/D is started. An operation signal from a limit switch S is applied to an operation unit 11 and an input processing unit 9 in a computer A. A deviation signal from the input processing unit 9 is compared with a deviation on a deviation setting unit 12 by an operation unit 13. The result of the comparison is applied to an information unit 16. The change of the contact of the limit switch S is detected by the operation unit 11 to entirely close the bypass valve for the main steam stop valve at 15.
