Abstract

The invention relates to a subunit-level sequence control logic module for a nuclear power plant. The subunit-level sequence control logic module comprises a plurality of auxiliary machines arranged at the subunit level, wherein a plurality of accessory facilities are arranged on the auxiliary machines; a logic control circuit is arranged according to the process system operating sequence of the auxiliary machines and the accessory facilities and is provided with a plurality of signal input ends and a plurality of signal output ends; the auxiliary machines and the accessory facilities are provided with state feedback signal output ends which are electrically connected with the signal input ends, and the signal output ends are connected with control signal input ends of the auxiliary machines and the accessory facilities; the logic circuit judges working states of the auxiliary machines and the accessory facilities on corresponding state feedback loops according to received state feedback signals, and outputs control signals from the signal output ends to control the auxiliary machines and the accessory facilities to start or stop operation according to the process system operating sequence of the auxiliary machines and the accessory facilities, and a subunit-level sequence control logic structure for the nuclear power plant is formed. The subunit-level sequence control logic module for the nuclear power plant has the outstanding beneficial effects of high efficiency, safe and reliable operation, good economic performance and the like.

Description

technical field [0001] The invention relates to a nuclear power plant subgroup-level sequential control logic module and an application method thereof, belonging to the technical field of nuclear power plant control equipment. Background technique [0002] The sequence control of thermal power plants basically adopts the three-level control of drive level, sub-function group level and unit function group level, which plays an increasingly important role in the safe and economical operation of large-scale units. At present, the control of nuclear power plants mainly adopts single operation, supplemented by chain control. For example, the start or stop operation of an auxiliary machine and its auxiliary equipment or a certain local related process system is based on the operation of a single device. The operator can start, stop or open and close a single device through the operator station, which belongs to the drive Level control, interlocking control between devices through...
