Abstract

The invention discloses a nuclear power plant reactor protection system and relates to the technical field of nuclear power plant reactor protection. The invention includes a selection rule library, an equipment selection unit, an equipment library, an active detection unit, a response monitoring unit, a data integration unit, a core processing unit, a management unit, a display unit and a storage unit. The present invention randomly selects each equipment in the nuclear power plant reactor through the equipment selection unit, selects the equipment once every T1 time to obtain the selected equipment group Xj, calculates the selection value Q with the help of related algorithms and formulas, and uses the calculated selection value Different values ​​of Q and corresponding sizes are used to select the equipment, and each time several are selected, the selected number and equipment are randomly selected; to avoid manual targeting of some equipment; at the same time, it is tested according to the selected equipment, and according to the results of the test, it can Realize the evaluation of the reliability of the whole protection system; the invention is simple, effective and easy to be practical.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant reactor protection, in particular to a nuclear power plant reactor protection system. Background technique [0002] The patent with the publication number of CN101968974A discloses a nuclear power plant reactor protection system, including: at least one lower layer acquisition device, the lower layer acquisition device is connected to an instrument group of the nuclear power plant reactor, and the instrument group includes process measuring instruments and nuclear instruments. The lower layer acquisition device collects and processes the process signal of the process measurement instrument and the nuclear power signal generated by the nuclear instrument, and generates a digital signal by comparing with the set process signal threshold and the nuclear power signal threshold; the upper layer processing device, and the lower layer acquisition device Connect to receive the digital signal g...
