Nuclear power plant diversity driving system, nuclear power plant diversity driving method and diversity protection system

Abstract

Embodiments of the invention disclose a nuclear power plant diversity driving system, a nuclear power plant diversity driving method and a diversity protection system. The nuclear power plant diversity driving system is used for protecting the safety of a nuclear power plant when a reactor protection system fails, and comprises a signal receiving module used for receiving a detection signal, logic processing modules used for logically processing the detection signal to judge whether there is a design basis accident and generating a driving signal when judging that there is a design basis accident, and a signal output module used for outputting the driving signal to an actuator to drive the actuator to act. According to the invention, a design basis accident can be detected automatically, and a driving signal can be generated correspondingly to automatically make the actuator act.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to a nuclear power plant diversity drive system and method, and a diversity protection system. Background technique [0002] Due to its simplified control logic, flexible configuration capability and powerful self-diagnosis function, the digital instrument control system (DCS) has been vigorously developed and applied in the safety level control system of nuclear power plants. Protection System. However, digital protection systems are susceptible to common-cause failures due to centralization of functions, shared software, and widespread adoption of communication technologies. For the reactor protection system that realizes the reactor safety function, when a design basis accident occurs, if the digital protection system cannot perform its key functions due to common cause failures, the accident will develop into a beyond design basis accident and further endanger the safety ...
