Abstract

The present invention relates to a monitoring block for real-time integrity evaluation during the operation of a power plant hydraulic actuator, which can monitor the operation state of a hydraulic actuator in real time during the operation of the hydraulic actuator to ensure the integrity of the hydraulic actuator. To this end, the monitoring block for real-time integrity evaluation during the operation of a power plant hydraulic actuator comprises at least one among: a drive monitoring block which connects the hydraulic actuator with a driving valve for adjusting a working oil for the operation of the hydraulic actuator and forms a path through which the working oil is transferred between the hydraulic actuator and the driving valve; an opening and closing monitoring block which connects the hydraulic actuator with an opening and closing valve for determining whether the working oil is supplied to the hydraulic actuator and forms a path through which the working oil is transferred between the hydraulic actuator and the opening and closing valve; and an emergency monitoring block which connects the hydraulic actuator with an emergency stop valve adjusting the working oil in order to control the operation of the hydraulic actuator and forms a path through which the working oil is transferred between the hydraulic actuator and the emergency stop valve.

Description

technical field [0001] The invention relates to a monitoring block for real-time soundness evaluation of a hydraulic actuator in a power plant, in particular to a hydraulic actuator that monitors the hydraulic actuator in real time during operation to ensure the soundness of the hydraulic actuator Monitoring block for real-time soundness evaluation of power plant hydraulic actuators during operation. Background technique [0002] Generally, nuclear power plants or thermal power plants include a fluid generator that generates fluid, a turbine that receives fluid to generate rotational force, a generator that generates electricity based on the power of the turbine, and a cooler for cooling the turbine. At this time, the fluid supplied to the turbine is regulated by the turbine valve, which is controlled by the hydraulic oil supplied to the hydraulic actuator. So fluid can be supplied to the turbine according to the control of the turbine valve. And hydraulic actuators can be...
