Abstract

The invention discloses an output control method and an output control system of a nuclear power plant reactor protection system, which belong to the field of nuclear power technologies. The output control method comprises the steps of: S1, carrying out transmission processing on an input signal of a nuclear power plant protection system so as to generate an output signal at an output end of the nuclear power plant protection system, and carrying out signal quality judgment on the output signal to obtain a judgment result; S2, retrieving a preset default value to perform numerical value replacement on the output signal when the judgment result indicates that the signal quality of the output signal is ''poor''; S3, and carrying out logic operation and subsequent control and display according to the default value. According to the output control method and the output control system, an existing output control method of the nuclear power plant reactor protection system is optimized, thus the optimized output control method can satisfy functional requirements of the default value of the nuclear power plant reactor protection system, and can reduce the influence of implementation of functions of the default value on other functions and performances of the system.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to an output control method and system of a nuclear power plant reactor protection system. Background technique [0002] At present, nuclear power plants maintain their safe and normal operation by setting up a protection system. The nuclear power plant protection system receives the detection data uploaded by on-site execution equipment (such as temperature sensors, pressure detection instruments, etc.), and judges whether the on-site operation status is within the controllable range based on the detection data. and when some data indicate that the on-site operation status is not good, issue corresponding control instructions to the on-site control station to adjust the operation status of the on-site equipment so that the reactor is in a safe state. For example, the nuclear power plant protection system detects a After the pressure signal of the loop regulator is lower than ...
