Turbine bypass control device, steam system, turbine bypass control method, and program

摘要

PROBLEM TO BE SOLVED: To provide a turbine bypass control device, a steam system, a turbine bypass control method, and a program capable of controlling the pressure in a header at the time of turbine trip even if the flow rate of steam flowing to a turbine is different. A turbine bypass control device (4) includes a trip signal acquisition unit (62) that acquires a trip signal from a turbine, and a first flow rate acquisition unit (63) that acquires a first flow rate (FR1) related to a detected flow rate of steam flowing to a turbine. And a bypass opening control unit 64 that controls the opening of the bypass valve of the turbine bypass line in relation to the trip signal PSD and the first flow rate FR1. [Selection diagram] Fig. 3
