Abstract

The invention discloses a debugging method of a nuclear power plant half-speed turbine monitoring system. The debugging method includes the following steps that S1, after a drawing is checked, and correct wiring of a control cabinet is guaranteed, the control cabinet is powered up, and verification of sensor characteristics is conducted by using a semi-physical verification platform; and after the control cabinet is powered up and the verification of the sensor characteristics is finished, verification of a channel below the semi-physical verification platform is conducted; S2, a sensor is installed; S3, after a measuring channel from the sensor to a display terminal is built, a monitoring instrument is adjusted by comparing a measuring value and a display value; and S4, jiggering, impulse starting and grid combining of a turbine unit are finished, and comparison of mechanical measurement and instrument control measuring value is conducted during on-load so as to verify whether unit operation requirements are met. The debugging method can solve the problem that static characteristic inspection can not be conducted before installing of the sensor, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of nuclear power, more specifically, to a debugging method for a half-speed steam turbine monitoring system in a nuclear power plant. Background technique [0002] The steam turbine monitoring system is a reliable, multi-channel instrument measurement and analysis system, which is used to continuously measure the mechanical and physical parameters of the steam turbine rotor and cylinder. As a key system to monitor and protect the safe operation of the unit, the steam turbine monitoring system adopts the following debugging methods in conventional thermal power: [0003] (1) Check and proofread the drawings before installing the sensor (attached with front end and extension cable); [0004] (2) Install the control cabinet and modules of the steam turbine monitoring system, check the wiring, and power on the control cabinet; [0005] (3) Check the configuration settings of the steam turbine monitoring system...
