Integrated testing method and system for digital protection system of high temperature gas-cooled reactor

Abstract

The invention discloses an integration testing method and system for a digital protection system of a high temperature gas cooled reactor and belongs to the technical field of the nuclear reactor. The method comprises the following steps of: S1, starting a corresponding testing module according to a testing instrument, and calling a testing algorithm corresponding to the function of the testing module so as to generating a testing vector of a monitoring variable of the digital protection system of the high temperature gas cooled reactor; S2, calculating and converting the testing vector to generating a signal in accordance with an interface of the protection system, and simultaneously, sending the generated simulated monitoring variable signal to signal input interfaces of a plurality of redundant channels of the protection system; and S3, acquiring testing data in real-time, carrying out comparison and statistic analysis on the acquired testing data and the predicted result, and judging whether the safety function and performance of the protection system has met the predicted requirements according to the results of comparison and statistic analysis. The invention can be used for determining whether the safety function and performance has met the predicted requirements at the system integration stage of the protection system.

Description

technical field [0001] The invention relates to the technical field of nuclear reactors, in particular to an integrated testing method and system for a digital protection system of a high-temperature gas-cooled reactor. Background technique [0002] The high-temperature gas-cooled reactor is an advanced reactor that uses coated particles without a metal cladding as fuel, graphite as a moderator, and helium as a coolant. The core outlet temperature is high. High-temperature gas-cooled reactors have inherent safety, wide utilization of thermal energy, high thermal efficiency, easy operation and management, great flexibility in fuel selection, and low fuel consumption. High-temperature gas-cooled reactors have good application prospects in small and medium-sized nuclear power plants, nuclear power plants in arid regions, nuclear energy coal gasification and liquefaction, and hydrogen production. [0003] The protection system of the high temperature gas-cooled reactor is one o...

Problems solved by technology

[0007] At present, the existing integrated test system for the digital protection system in China is the integrated test system for an experimental reactor protection system in Tsinghua University. The integrated test system is based on DCS (Distributed Control System, distributed control system). Its test software and The human-machine interface is implemented in the same computer, the real-time performance of the test and the synchronization performance of signal generation are poor, and the system reliability is not high, and there is no test report function

[0008] In addition, the domestic Beijing Guangli Nuclear System Engineering Co., Ltd. has a test device for the logic function test of the reactor protection system, but the test device cannot be used for the performance test of the protection system; foreign countries have test devices for the purpose of periodic testing of the protection system or systems (such as the TXS Test Machine of AREVA NP Company of the United States, the UTS of the Institute of Computer and Automation of the Hungarian Academy of Sciences, etc.), and the above-mentioned test devices or systems for periodic test purposes can only protect one or more protection systems for a single channel.
