Description

Technical Field

[0001] The utility model relates to the technical field of nuclear power plant simulators, and particularly relates to a dual-host version multi-functional simulator for a high-temperature gas-cooled reactor nuclear power plant. Background Art

[0002] A full-scope simulator of a nuclear power plant, also called a full-scale simulator, replicates the building structure, environmental layout, and functional layout of the main control room of a nuclear power plant, and fully and realistically reproduces the main control room of the nuclear power plant. A full-scope simulator of a nuclear power plant is a key device for the construction of a nuclear power plant project. Each newly built nuclear power plant needs to be equipped with at least one full-scope simulator for conducting operator training and license examinations, and providing a safe and reliable tool for operators and administrators to improve their operation and management technical levels. The full-scope simulator of a nuclear power plant integrates technologies in many fields such as reactor engineering, thermal power, electricity, instrument control, computer, and digital calculation.

[0003] A multi-functional simulator of a nuclear power plant uses a microcomputer as a working platform, simulates the physical, technological, and control processes of a nuclear power plant through a simulation mathematical model, and uses a computer graphics interface as a man-machine interface. The teaching simulator of a nuclear power plant can be used for the principle training in aspects such as the physics, thermal engineering, control, and electricity of a nuclear power plant, and can also realize the primary training of operation through the graphical operation interface of the power plant system. The multi-functional simulator of a nuclear power plant controls the window of the soft operation switch (virtual device switch) of the device popped up in the simulator system diagram through a mouse for operation. The simulator simulates the main contents of the main control room and local control of a reference nuclear power plant, so that the simulator can complete the main operations during the start-up, shutdown, power increase and decrease, accidents, and transients of the unit. The multi-functional simulator of a nuclear power plant installed with a simulator maintenance tool can also be used for the research of control systems and process systems and the simulation experiment of auxiliary design.

[0004] At present, the multi-functional simulator of HTR-PM (High Temperature Reactor-Pebblebed Modules) only has one host. After the unit of the high-temperature gas-cooled reactor nuclear power plant is put into commercial operation, data upgrade of the full-scope simulator of HTR-PM is required. During the upgrade, different unit suppliers will be restricted by the fact that there is only one host and they cannot work simultaneously. Content of the Utility Model

[0005] In view of this, the embodiment of the utility model provides a dual-host version multi-functional simulator for a high-temperature gas-cooled reactor nuclear power plant. During the data upgrade work of the full-scope simulator of HTR-PM, different unit suppliers can work simultaneously without being restricted by the fact that the single-host version multi-functional simulator only has one host and cannot work simultaneously.

[0006] The utility model provides a dual-host version multi-functional simulator for a high-temperature gas-cooled reactor nuclear power plant, including: a first computer and a second computer, wherein:

[0007] A virtual unit group is arranged on the first computer, and a virtual DCS engineer station virtual machine, a first reactor operator station virtual machine, a server virtual machine group, and a first physical network card unit group which are all connected to the virtual network unit group;

[0008] A second physical network card unit group is arranged on the second computer, and a second reactor operator station virtual machine, a conventional island operator station virtual machine, a teaching control console client, and a model simulation server which are all connected to the second physical network card unit group;

[0009] The first physical network card unit group and the second physical network card unit group are connected by a network cable.

[0010] The dual-host version multi-functional simulator for a high-temperature gas-cooled reactor nuclear power plant provided by the embodiment of the utility model overcomes the communication problems of the physical networks of two computers and the internal virtual networks, and realizes network intercommunication among various devices on the premise of not changing the original engineering network configuration; a large amount of equipment and site space can be saved, and it is convenient for transplantation, replication, installation, management and maintenance; the model-side engineer and the virtual DCS engineer respectively operate one host, and in the data upgrade work of the HTR-PM full-scope simulator, both parties can carry out their respective work simultaneously, without being restricted by the fact that the single-host version multi-functional simulator has only one host and cannot carry out work simultaneously.

[0011] In an optional implementation manner, the server virtual machine group includes: a historical server virtual machine, a CI server virtual machine, an NI server virtual machine, and a computing server virtual machine;

[0012] The virtual network unit group includes: a first virtual adapter and a second virtual adapter;

[0013] The historical server virtual machine, the computing server virtual machine, and the first reactor operator station virtual machine are respectively connected to the first end of the first virtual adapter;

[0014] The virtual DCS engineer station virtual machine, the CI server virtual machine, and the NI server virtual machine are respectively connected to the second end of the first virtual adapter and to the second virtual adapter.

[0015] In an optional implementation manner, the first physical network card unit group includes: a first physical network card and a second physical network card, wherein:

[0016] The first physical network card is connected to the second end of the first virtual adapter;

[0017] The second physical network card is connected to the NI server virtual machine.

[0018] In an alternative embodiment, the second physical network card unit group includes: a third physical network card and a fourth physical network card, where:

[0019] The third physical network card is respectively connected to the second reactor operator station virtual machine, the conventional island operator station virtual machine, and the first physical network card;

[0020] The fourth physical network card is respectively connected to the teaching console client, the model simulation server, and the second physical network card.

[0021] In the embodiment of the present utility model, by virtualizing network devices and physical network cards and connecting them to various devices, the communication problems between the physical network of the computer and each internal virtual network are solved, and network interconnection between devices is achieved without changing the original engineering network configuration.

[0022] In an alternative embodiment, the first virtual adapter and the second virtual adapter communicate with the respective virtual machines they are connected to through the Host only network.

[0023] In the embodiment of the present utility model, communication between virtual machines, between virtual machines and the host is achieved through the Host only network, but virtual machines are not allowed to communicate with the external network, thus building an internally secure isolated network.

[0024] In an alternative embodiment, the first physical network card, the second physical network card, and the third physical network card communicate with the respective virtual machines they are connected to in a bridging manner.

[0025] In the present utility model, the second reactor operator station virtual machine and the conventional island operator station virtual machine located on the second computer exchange data with the server virtual machine group and the virtual DCS engineer station through the first virtual adapter in the first computer, and the teaching console client and the model simulation server exchange data with the NI server in the first computer. However, since cross-platform communication is required simultaneously, cross-platform communication connection is achieved through the bridging method of setting physical network cards on the two host platforms respectively.

[0026] In an alternative embodiment, the teaching console client and the model simulation server have the same network address as the fourth physical network card.

[0027] In the present utility model, the model simulation server and the teaching console client are not virtualized and are directly installed in the second computer, which can reduce the host operation load of the second computer. Since they are not virtualized, the teaching console client and the model simulation server directly call the network address of the fourth physical network card for communication.

[0028] In order to more clearly illustrate the specific embodiments of the present invention or the technical solutions in the prior art, the following will briefly introduce the drawings required for use in the description of the specific embodiments or the prior art. Obviously, the drawings in the following description are some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0030] Figure 2 It is a schematic diagram of equipment connection of a dual-host version multifunctional simulator for a high-temperature gas-cooled reactor nuclear power plant provided by an embodiment of the present invention. Specific Embodiments

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0032] Based on the fact that the current simulator system requires multiple computer devices, in this embodiment, without changing the existing full-scope simulator system and software and hardware structure, the system and software and hardware structure are streamlined. The equipment and network are virtualized by using virtual machine and virtual network technologies. The structural diagram of the simulator system of the streamlined system and software and hardware devices is as Figure 1 shown.

[0033] In order to overcome the limitation that in the data upgrade work of the HTR-PM full-scope simulator, different unit suppliers can carry out their respective work simultaneously, without being restricted by the fact that the single-host version multifunctional simulator has only one host and cannot carry out work simultaneously. In this embodiment, two microcomputers are used as the working platform, and the optimized simulator system and software and hardware devices are realized by using virtual machine and virtual network technologies.

[0034] Specifically, this embodiment provides a dual-host version multifunctional simulator for a high-temperature gas-cooled reactor nuclear power plant, as Figure 2 shown, including: a first computer and a second computer, and appropriate operating systems and virtual machine software are installed in the first computer and the second computer, where:

[0035] A virtual DCS engineer station virtual machine, a first reactor operator station virtual machine (the 1# reactor operator station virtual machine in Figure 2 ), a server virtual machine group, and a first physical network card unit group are provided on the first computer; a second physical network card unit group, a second reactor operator station virtual machine (the 2# reactor operator station virtual machine in Figure 2 ), a conventional island operator station virtual machine, a teaching console client, and a model simulation server are provided on the second computer; the first physical network card unit group and the second physical network card unit group are connected by a network cable.

[0036] In the multi-functional simulator with dual hosts for high-temperature gas-cooled reactor nuclear power plants provided in this embodiment, the model-side engineer and the virtual DCS engineer operate one host respectively. During the data upgrade work of the HTR-PM full-scope simulator, both parties can carry out their respective work simultaneously, without being restricted by the single-host limitation of the single-functional simulator where only one host is available and work cannot be carried out simultaneously; it overcomes the communication problems of the physical network of 2 microcomputers and the internal virtual networks, and realizes network interconnection between devices without changing the original engineering network configuration.

[0037] Specifically, in order to virtualize the software and hardware devices originally working under the 32-bit system, the server virtual machine group set on the first computer, as Figure 2 shown, includes: a historical server virtual machine, a CI server virtual machine, an NI server virtual machine, and a computing server virtual machine; a second operator station virtual machine (the 2# reactor operator station virtual machine in Figure 2 ) and a conventional island operator station virtual machine are set in the second computer, and the operating systems and engineering software of the above virtual devices are consistent with the corresponding device parameters in Figure 1 .

[0038] In order to virtualize network devices, the virtual network unit group set on the first computer includes: a first virtual adapter and a second virtual adapter, and the network settings under the virtual machine are consistent with the network parameters in Figure 1 . Specifically, the historical server virtual machine, the computing server virtual machine, and the first reactor operator station virtual machine (the 1# reactor operator station virtual machine in Figure 2 ) are respectively connected to the first end of the first virtual adapter; the virtual DCS engineer station virtual machine, the CI server virtual machine, and the NI server virtual machine are respectively connected to the second end of the first virtual adapter and to the second virtual adapter.

[0039] The first physical network card unit group set on the first computer includes: a first physical network card and a second physical network card, where: the first physical network card is connected to the second end of the first virtual adapter; the second physical network card is connected to the NI server virtual machine.

[0040] The second physical network card unit group set on the second computer includes: a third physical network card and a fourth physical network card, where: the third physical network card is respectively connected to the second reactor operator station virtual machine, the conventional island operator station virtual machine, and the first physical network card; the fourth physical network card is respectively connected to the teaching console client, the model simulation server, and the second physical network card.

[0041] Figure 2 The first virtual adapter, the first physical network card, and the third physical network card in jointly implement Figure 1 the function of the Level2 network in; Figure 2 The virtual second virtual adapter in implements Figure 1 the function of the Level1 network in; Figure 2 The second physical network card and the fourth physical network card in jointly implement Figure 1 the function of the Level0 network in.

[0042] In this embodiment, the first virtual adapter and the second virtual adapter communicate with the respective virtual machines they are connected to through the Host only network. The Host only network is a network mode in the virtualization environment, which allows communication between virtual machines, between virtual machines and the host, but does not allow virtual machines to communicate with the external network. This network configuration builds an internally secure isolated network.

[0043] Since the second reactor operator station virtual machine and the conventional island operator station virtual machine located on the second computer exchange data with the server virtual machine group and the virtual DCS engineer station through the first virtual adapter in the first computer, and the teaching console client and the model simulation server exchange data with the NI server in the first computer, but since cross-platform communication is required at the same time, cross-platform communication connection is realized by bridging the physical network cards set on the two host platforms respectively.

[0044] Specifically, create a virtual network bridge on the host, connect the physical network adapter of the host and the virtual network adapter of the virtual machine to this network bridge, select the bridged network mode for each virtual machine, and connect to the created virtual network bridge. Each virtual machine will obtain an independent IP address in the local area network. The virtual machine can communicate with external devices like other devices in the local area network, can directly access other devices through this address, and external devices can also access the virtual machine through the IP address. The bridged network makes the virtual machine seamlessly connected to other devices in the local area network.

[0045] In this embodiment, the model simulation server and the teaching control console client that originally operated under the 64-bit system are not virtualized and are directly installed in the second computer, which can reduce the operating load of the second computer. The relevant device parameters are the same as those of the device in Figure 1 and remain consistent. Since there is no virtualization processing, the teaching control console client and the model simulation server directly call the network address of the fourth physical network card for communication.

[0046] The multi-functional simulator with dual-host version for high-temperature gas-cooled reactor nuclear power plants provided by the embodiments of the present invention does not change the existing full-scope simulator system, software and hardware structure, nor the simulation method and functions of the existing full-scope simulator. The system structure, network layout, operating system, engineering software, and engineering files of the multi-functional simulator with dual-host version are the same as those of the existing full-scope simulator equipment, and its simulation effect and operation response are the same as those of the existing full-scope simulator; it can realize the simulation of nuclear power plant physics, thermal engineering, control, and electrical aspects, enabling the simulator to complete the main operations during unit startup and shutdown, power increase and decrease, accidents, and unit transients. It can be used for data upgrade and test verification work of the HTR-PM full-scope simulator, as well as for developing and verifying teaching and examination scenarios, for modifying and verifying the deviations and changes of the simulator, and at the same time, it can save a large amount of equipment and site space, and is convenient for transplantation, replication, installation, management, and maintenance.

[0047] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
