Example Embodiment

[0019] The technical solution of the present invention aims at the existing means of monitoring the electrical system and auxiliary systems of the nuclear power plant, which cannot realize centralized monitoring, and the monitoring of the electrical system of the nuclear power plant can only use limited hard wiring or communication interfaces to transmit very limited system data to the operating personnel , and cannot provide a large amount of data for the nuclear power plant information system (KNS). In order to achieve centralized monitoring and solve the problem of providing data for the nuclear power plant information system, it is more important to solve the problem that the electrical system and auxiliary systems of the nuclear power plant cannot be effectively monitored due to the different decommissioning periods of the units in the nuclear power plant group reactor management. like figure 1 As shown, the nuclear power plant public control network of the present invent...

Abstract

The invention relates to a common control net for a nuclear power station, which comprises an electrical control subring net, a sub-control subring net and a monitoring layer ring net, wherein the electrical control subring net is used for being connected with a nuclear power station electrical system, and controlling and monitoring the connected nuclear power station electrical system; the sub-control subring net is used for being connected with a sub-system of the nuclear power station, and controlling and monitoring the connected sub-system of the nuclear power station; and the monitoring layer ring net is respectively connected with the electrical control subring net and the sub-control subring net in order to exchange data with the electrical control subring net and the sub-control subring net respectively and sends a corresponding operation command. The technical scheme of the invention solves the problem that the common system can not be controlled, which is generated by different retirement periods caused by different service life in the nuclear power station management; the invention can not be influenced by the set retirement, realizes the network control of the common system, improves the information exchange speed and increases the information exchange volume, reduces operators, improves the operable rate and the usability of the common system, and further improves the economy of the nuclear power station operation.

Description

technical field [0001] The invention relates to a public control network, more specifically, to a nuclear power plant public control network. Background technique [0002] In the face of large-scale construction of nuclear power plants, due to the batch and phased construction of each unit under the same site conditions of the nuclear power plant, and the long construction period, the life cycle of the power plant is limited by the main equipment of the nuclear island and cannot be extended indefinitely. (The control of the public system of the whole plant is now the control method of multiple units is the way of administrative authorization. The operation is carried out in the DCS (Digital Control System) main control room of No. 1 unit, and the cabinets are placed in the electrical workshop of No. 1 and No. 2 units. ), and after Units 1 and 2 are decommissioned, it is necessary to consider that the decommissioning time of the subsequent units is different from that of Unit...
