Nuclear power plant electric head clamp hybrid simulation testing system and method

Abstract

The present invention relates to a nuclear power plant electric head clamp hybrid simulation testing system and method. The testing system comprises a front control device, an AC signal device, a collection control device, a collection adaption device, and a DC signal device. The front control device receives different test cases and analyzing each test case into different control commands. The AC signal device sends an AC testing signal to the collection adaption device. The DC signal device sends a DC testing signal to the collection adaption device. The collection adaption device sends the AC testing signal and the DC testing signal to the collection adaption device. The collection adaption device conditions the AC testing signal and the DC testing signal and output the signals to an electric head clamp to carry out testing, and the tested feedback signal is processed and uploaded to a front control device. According to the technical scheme of the invention, the clamp input and output pin monitoring and analysis in an electric head are realized, and the problem of the high professional requirement of a laboratory assistant by a test is solved.

Description

technical field [0001] The invention relates to a nuclear power plant equipment simulation test technology, and more specifically relates to a hybrid simulation test system and method for electric head clips of a nuclear power plant. Background technique [0002] The electric head is an important equipment in the industrial automation process control link, and the intelligent electric head is widely used in the production and operation of nuclear power plants. At present, the IQ series intelligent electric heads newly launched by ROTORK in the 1990s are widely used in conventional island nuclear power plants. They are important components in the stator cooling water system of nuclear power plant generators, and have great influence on the working performance of the entire protection system. have an important impact. Safety and reliability are the basic principles of nuclear power plants. Therefore, how to detect the working performance of the electric head and prevent accid...

AI Technical Summary

Problems solved by technology

At the same time, most equipment maintenance personnel do not have enough understanding of the internal structure and functions of the electric head. As a result, the current detection of the electric head is generally a simple power-on test of the entire device. This method can only roughly reflect whether the electric head can work normally. , and cannot detect the performance status of each card inside the electric head

When this method causes the electric head device to fail to work normally, since the cause and location of the fault are unknown, even if most of the internal clamps work normally, the entire electric head must be replaced, which causes a huge waste of resources

In addition, this detection method does not need to disassemble the electric head, and nuclear power plant operators and maintenance personnel cannot understand its internal structure and functions well, which brings difficulties to equipment management and maintenance.
