Common control net for nuclear power station

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...
