Technical Field

[0001] The utility model relates to the technical field of power plants, in particular to a public unit system of a nuclear power plant. Background Art

[0002] At present, in nuclear power plants, nuclear power units include unit units and common units. Each unit is used relatively independently and has an independent distributed control system (DCS) to monitor and control the equipment of the unit. Common units are some systems shared by two unit units or the whole plant, such as REA (reactor shed and water supply system) boron water tank, ASG (auxiliary water supply system) water supply tank, common electrical switch and other systems.

In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0062] The present invention can be used in many general or special computing device environments or configurations, such as personal computers, server computers, handheld devices or portable devices, tablet devices, multi-processor devices, and distributed computing environments including any of the above devices or equipment.

[0063] Reference Figure 1 , is a schematic diagram of the public unit network architecture of the existing nuclear power plant unit system. In the figure, 1 includes unit units 1, 2, 3, 4, 5, and 6 of the power plant; units 7, 8, and 9 are shared by two units; and unit 0 is shared by the whole plant; Figure 1 The connection architecture between units 5 and 6, unit 7 shared by units 5 and 6, and unit 0 shared by the entire plant is shown as an example. The connection relationship between units 1, 2, 3, 4 and their shared units and unit 0 shared by the entire plant is not shown.

[0064] Figure 1 The connection structure between unit 5, common unit 7 and common unit 0 for the whole plant shown in the figure is the same as the connection structure between unit 6, common unit 7 and common unit 0 for the whole plant. The components involved in the connection structure between unit 5, common unit 7 and common unit 0 for the whole plant are numbered. The meanings of the numbers are as follows:

[0065] 1 is the power plant computer information and control system (i.e. KIC in the figure), 2 is the unit management network (i.e. Unit5 PICS net in the figure and Unit6 PICS net in the figure), 3 is the unit server (i.e. the server between the unit management network and the unit control network), 4 is the unit control network (i.e. Unit5 Control net in the figure and Unit6 Control net in the figure), 5 is the public unit three-layer switch (i.e. the switch connected to the unit control network and the public unit control network), 6 is the unit control station, 7 is the public unit control network (i.e. Unit7 Controlnet in the figure), 8 is the public unit three-layer switch, 9 is the public unit control station, 10 is the public unit gateway, 11 is the public unit control network (i.e. Unit0 Control net in the figure), and 12 is the public unit control station for the entire plant.

[0066] like Figure 1 As shown, the Unit7 public unit and the Unit5 and Unit6 unit units realize cross-unit communication through the three-layer switch, and the Unit0 public unit and the Unit5 and Unit6 unit units realize cross-unit communication through the public unit gateway and the three-layer switch.

[0067] The implementation steps are as follows:

[0068] 1) 1 and 3 are connected to 2 via a Gigabit Ethernet cable;

[0069] 2) 3, 5, 6, and 8 are connected to 4 via a Gigabit Ethernet cable;

[0070] 3) 5 is connected to 7 via a Gigabit Ethernet cable;

[0071] 4) 7 is connected to 9 via a Gigabit Ethernet cable;

[0072] 5) 8 is connected to 10 via a Gigabit Ethernet cable;

[0073] 6) 10 is connected to 11 via a Gigabit Ethernet cable;

[0074] 7) 11 is connected to 12 via a Gigabit Ethernet cable;

[0075] 8) Set the route in 3, 6, 9, 10, and 12;

[0076] 9) Set the route in 5 and 8;

[0077] Public unit data monitoring path:

[0078] The common data monitoring path of the two units: 1→2→3→4→5→7→9;

[0079] The common data monitoring path for the entire plant: 1→2→3→4→8→10→11→12.

[0080] From the above content, it can be seen that the structure of the existing nuclear power plant public unit system has the following problems: when Unit5 and Unit6 monitor the Unit0 public unit data, the path is too long, the data transmission volume is small, the public unit FCS data to the unit display time is up to 2.5S, and the data transmission does not exceed 2000 points. In addition, the existing system architecture is complex to deploy. When the public unit communicates with multiple units (Unit0 communicates with Unit1~6), multiple public unit gateways need to be configured. Moreover, the FCS (control station) and the public unit gateway are implemented based on the embedded operating system, and the configuration requires maintenance tools. The network configuration is complex and the performance is low.
