Periodic test device and method for high temperature reactor nuclear power plant protection system

Abstract

The invention belongs to the technical field of measurement and control of nuclear power plant safety protection system. For solving the technical problems of complex operation and low automation degree in the technical scheme of periodic test of a nuclear power plant protection system in the prior art, the invention provides a periodic test device and method for a high temperature reactor nuclearpower plant protection system. The device comprises an upper computer, a lower computer and a signal conditioning module; the upper computer is set to be capable of inputting a variety of test operation information, displaying test operation results and communicating with the high temperature reactor nuclear power plant protection system to be tested; the lower computer is provided with a data acquisition board card for output and acquisition of hard wiring data corresponding to the high temperature reactor nuclear power plant protection system to be tested and a controller; the signal conditioning module is set up to realize conversion and transmission of hard wiring data between the data acquisition board card and the high temperature reactor nuclear power plant protection system to betested, and protocol conversion and transmission of communication data between the upper computer and the high temperature reactor nuclear power plant protection system to be tested.

Description

technical field [0001] The invention relates to the technical field of measurement and control of a nuclear power plant safety protection system, in particular to a periodic test device and method for a high temperature reactor nuclear power plant protection system. Background technique [0002] The high-temperature reactor nuclear power plant protection system is one of the important safety systems of the high-temperature gas-cooled reactor. It is used to continuously monitor the protection variable determined according to the accident analysis. The state of the accident exceeds the specified safety limit, or when the design basis accident occurs, it can stop the accident from expanding or alleviate the consequences caused by it. [0003] The periodic test of the protection system of the high temperature reactor nuclear power plant is the premise to ensure the safe operation of the protection system of the high temperature reactor nuclear power plant in the actual operation...
