Abstract

PURPOSE:To restrict the fluctuation of reactor pressure in the device in the caption used for nuclear power generation, etc., by quickly opening a main steam bypass valve of a turbine only when an abnormality occurs in the turbine. CONSTITUTION:The control device is formed to permit a bypass valve to be quick-opened only when an abnormality is detected in a turbine by inputting a signal from a turbine-abnormality detection circuit to a control circuit of a bypass valve quick-opening valve 104 for quickly opening the bypass valve. The abnormality detection circuit is formed by a load-shutdown detection circuit 400, a tripping relay 500, and OR circuit for inputting signals from a power load unbalance detection circuit 201, and quickly opens the bypass valve when a deviation of the valve-opening above a specified value is detected by a bypass valve opening deviation detection circuit 103 and an abnormality detection signal is given. The cooperative control of a heating valve and the bypass valve is thus possible when any fluctuation occurs in the system, and the reactor pressure fluctuation can be restricted.
