Abstract

The invention discloses a diversified driving method for a nuclear power station. The method comprises the following steps: acquiring parameter information of each process in operation of the nuclear power station; comparing the parameter information of each process with a preset corresponding set value; outputting a signal for driving the execution of automatic functions if more than one but not all of the process parameter information exceeds the corresponding set value, wherein the automatic functions include an automatic tripping function of a steam turbine, an automatic start function of an auxiliary water supply electric pump, an automatic start function of a steam driven pump, a main steam automatic isolation function, a main water supply automatic isolation function and an automatic pump shutdown function of a reactor coolant pump. Besides, the invention also discloses a diversified driving device and a diversified driving system for the nuclear power station.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and more specifically, the invention relates to a variety driving method, device and system of a nuclear power plant. Background technique [0002] The safety-level instrumentation and control system of nuclear power plants first adopted the simulation technology. Due to the characteristics of the simulation equipment, the measures taken in the system design to prevent certain types of common cause failures (such as: equipment identification, periodic tests, etc.) Many years of operating experience, so common cause failures in simulated systems are usually not assumed. With the development of digital technology, distributed / digital control system (Distributed / Digital Control System, DCS) system has been gradually applied to the control field of nuclear power plants. Compared with analog equipment, digital equipment has many advantages, such as self-diagnosis, reliability, availability, and...
