Problems solved by technology

[0007] Various faults occur in nuclear power plants under various operating conditions, and the faults bring about the output of blocking commands. When faults are issued by mistake, the function of the blocking commands causes the equipment to refuse to move, which brings risks to the operation safety of nuclear power plants.

Abstract

The invention discloses a nuclear power station rotating machine driving control method which comprises the steps that obtained signals are subjected to logic processing, and device-level control instructions are formed; the control instructions are converted to specific instruction signals which can be identified by rotating machine equipment, and feedback signals of the rotating machine equipment according to the specific instruction signals are received; according to the feedback signals, whether a fault happens to the rotating machine equipment is judged; and if yes, the rotating machine equipment is subjected to reset control. The nuclear power station rotating machine driving control method is a reliable nuclear power station rotating machine driving control technology, and safe operation of the rotating machine equipment under various working conditions can be guaranteed. In addition, the invention discloses nuclear power station rotating machine driving control device.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and more specifically, the invention relates to a driving control method and device for nuclear power plant turning. Background technique [0002] At present, many nuclear power projects adopt the digital instrument control system (Distributed Control System, DCS) to realize the production process control and centralized operation and monitoring of nuclear power plants. As the logic diagram is the design input of DCS work design and configuration, the standardization and readability of the drawings are very important. The turning equipment of nuclear power plants refers to the nuclear island of nuclear power plants and the rotating equipment of conventional islands (such as water pumps and fans). Most power plants under construction use special modules for turning drive level to build the control logic of pumps and fans. The special module (pump / fan) for the turn-around driving stage is a ...
