Abstract

The invention belongs to the technical field of nuclear power station instrument control systems, aims to solve the technical problems that a test probably has safety risks and on-site driving devicesare probably falsely operated in the prior art, and provides a nuclear power station safety-class output control circuit test method and system which are safe and avoid non-disturbance conditions. The test method includes the steps: S1 connecting a maintenance test tool to a periodic test interface device; S2 enabling the periodic test interface device to be powered on before testing, and starting a project to be tested in a test frame; S3 inputting triggering signals on a test panel, and converting the triggering signals into test starting instructions by a control station in a nuclear powerstation reactor protection system; S4 receiving the test starting instructions by a safety-class output control circuit, outputting test detection results by the aid of a pulse mode, and receiving the detection results by the maintenance test tool through the periodic test interface device.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant instrument control systems, in particular to a test method and system for a safety level output control loop of a nuclear power plant. Background technique [0002] In order to ensure that the reactor protection system can reliably perform protection actions under abnormal conditions, it is necessary to conduct regular tests to verify the effectiveness of its protection functions and reduce the risk of failure of the protection system. For example, "Design of Periodic Test Plan for ACPR 1000 Reactor Protection System Based on Harmony System" published in the Journal of Nuclear Power Engineering, Volume 37, Issue 6, December 2016, records: Periodic testing of the protection system of nuclear power plants is the basic criterion for the design of the protection system. Normally, the periodic test of the protection system is divided into three sections: T1 test, T2 test and T3 test. Among...
