Description

Technical Field

[0001] The present application relates to the technical field of magnetic confinement fusion auxiliary heating, and in particular to a digital control system and method for a high-voltage power supply for auxiliary heating of a magnetic confinement fusion device. Background Art

[0002] The Chinese Tokamak Experimental Reactor (HL-3) is an important device for high-parameter magnetic confinement fusion research. It has the ability to burn core-level plasma and megawatt-level fusion power. In order to achieve the ignition temperature of plasma fusion, in addition to the ohmic heating method, four auxiliary heating methods are required to increase the plasma injection power, namely electron cyclotron resonance heating (ECRH), ion cyclotron resonance heating (ICRH), low hybrid current drive (LHCD), and neutral beam injection (NBI). In the tokamak device, in order to better play the corresponding performance of the four auxiliary heating systems, a one-to-one method is used to provide high voltage to each auxiliary heating system. Therefore, under the demand for high injection power, each auxiliary heating system requires multiple sets of high-voltage power supplies to meet the requirements. For the multiple sets of high-voltage power supplies for each auxiliary heating system, in large-scale device systems, conventional control methods will face the problems of remote control networking requiring multiple network ports and multiple addresses, office space requirements, and difficulty in data transmission and maintenance. In addition, when large-scale equipment is in operation, the only remote control interface only meets the unilateral control needs of power supply staff (demand side) and physical researchers (implementation side), which is not conducive to physical researchers to modify power supply parameters according to demand for power matching, and is not conducive to power supply staff to monitor the power supply operation status. In addition, the conventional control means are not coordinated enough with the central control system, resulting in inconsistent data storage formats, few data backup methods, and unsatisfactory visualization of power supply discharge under multiple conditions. It can only rely on the measurement system for viewing and analysis, and data redundancy is insufficient. Summary of the invention

[0003] In order to solve the problems faced by conventional control methods, such as the need for multiple networking addresses for remote control networking, the difficulty of data transmission and dimensionality, the present application proposes a digital control system and method for auxiliary heating high-voltage power supply of a magnetic confinement fusion device. The present application adopts a control scheme in which one host computer controls multiple controllers. The use of a data management center between the host computer and the controller effectively reduces the requirements for physical addresses, switches, etc. during networking communications. At the same time, in the data management center, the host computer and the controller perform two-way data transmission according to the custom port number method, which reduces the difficulty of data transmission and maintenance.

[0007] Each auxiliary heating system controls multiple controllers through its corresponding power supply host computer. The power supply host computer and the multiple controllers support the data management center networking mode. In this networking mode, the power supply host computer exchanges data with the multiple controllers through the data management center, that is, the power supply host computer packages the relevant control parameters of the multiple controllers and sends them to the data management center. The data management center parses the received data packets to obtain the relevant control parameters of each controller and sends them to the corresponding controller. The controller converts the electrical signal into an optical signal through a photoelectric conversion module, and uses the optical signal to drive, control and monitor the high-voltage power supply module.

[0008] In some embodiments, the power supply host computer and multiple controllers also support an independent operation networking mode.

[0013] In the power supply host computer control mode or in the client control mode, the controller can transmit corresponding control parameters back to the power supply host computer for data verification.

[0014] In some embodiments, the controller collects voltage, current and state data of the high-voltage power module and transmits them to the power host computer for storage and real-time display;

[0015] The data stored in the power supply host computer is backed up and stored in the server, central control system and client in the form of files, and visual display of discharge data is realized in the central control system and client.

[0018] Determine the power user, grant parameter control rights to the client or the power host computer through the power host computer, and obtain the discharge parameters stored in the EPIC server of the central control system through the server;

[0019] When client control is selected, the control parameters are transmitted to the power supply host computer through the server. The power supply host computer packages the received data and transmits it to the data management center. After being parsed by the data management center, it is transmitted to the corresponding controller. When power supply host computer control is selected, the control parameters are set directly through the power supply host computer and packaged and transmitted to the data management center. After being parsed by the data management center, it is transmitted to the corresponding controller.

[0020] The controller waits for the timing signal from the central control system, sends a driving signal through the photoelectric conversion module to control the operation of the high-voltage power supply module, and feeds back to adjust the output value of the high-voltage power supply module.

[0021] In some embodiments, the control method further comprises:

The illustrative implementation scheme of the present application and its description are only used to explain the present application and are not intended to limit the present application.

[0040] Example:

[0041] In order to meet the needs of one-control-many, multi-system coordination and isolation in the field of auxiliary heating control of magnetic confinement fusion devices, reduce networking address requirements, and reduce the difficulty of data transmission and maintenance, this embodiment proposes a digital control system for auxiliary heating high-voltage power supply of magnetic confinement fusion devices.

[0042] The auxiliary heating high-voltage power supply digital control system mainly includes a client, a server, a central control system, a power supply host computer, a data management center, a controller, etc.

[0043] The client, server, central control system, power host computer, and data management center are networked to realize data interaction. The data interaction between the client, central control system, and power host computer is realized in the service layer, with the server as the data transmission bridge, that is, the client and the server interact with each other, the central control system interacts with each other, and the power host computer interacts with each other. The central control system is the central control system of the magnetic confinement fusion device.

[0044] Each auxiliary heating system controls multiple controllers through the power host computer, supporting the data management center and independent operation networking modes. In the data management center networking mode, the power host computer can exchange data with multiple lower controllers through the data management center. In this networking mode, only the power host computer and the data management center are required to network, without the need for multiple networking addresses, which reduces the difficulty of data transmission and maintenance; in this networking mode, the power host computer packages the relevant control parameters of multiple controllers and sends them to the data management center. The data management center parses the received data packets to obtain the relevant control parameters of each controller and sends them to the corresponding controller. The controller converts the electrical signal into an optical signal through the photoelectric conversion module, and uses the optical signal to drive and control the high-voltage power module, as well as the status monitoring and signal measurement of the high-voltage power module. The photoelectric conversion module is then used to convert the monitoring and measurement optical signal into an electrical signal and send it to the controller. The controller sends it to the data management center for packaging and uploading to the power host computer. In the independent operation networking mode, the power host computer and multiple controllers directly interact in networking, that is, conventional control means. In this networking mode, the power supply host computer sends the relevant control parameters directly to the corresponding controller according to the networking address to drive and control the high-voltage power supply module and directly receive the monitoring and measurement signals of the high-voltage power supply module.

[0045] Optionally, each auxiliary heating system also supports client control, which requires the power host computer to obtain control authority to obtain relevant control parameters of the client. In this control mode, the relevant control parameters are set by the client, and the power host computer obtains the relevant control parameters of the client through the server and saves (updates) them locally before sending them to the data management center or controller.

[0046] Optionally, the discharge gun number and other related parameters stored in the EPICS server of the central control system are read by the server, and the client and the power supply host computer obtain the parameters related to the central control system through the server, which can easily realize networking and isolation with the central control system, effectively reduce the coupling of data transmission between the central control system and the power supply, and facilitate the inspection and maintenance of the power supply and various subsystems of the central control system.

[0047] Optionally, the high-voltage power supply discharge data saved by the power supply host computer is backed up and stored in the server, client and central control system in a unified data format, and the discharge data is visualized on the power supply host computer, client and central control system, thereby realizing data sharing, backup and visualization of the discharge data between systems. There is only one data transmission link between the power supply host computer, the client and the controller, and the sampling rate of the power supply host computer to the controller is not affected. The waveform data saved by the power supply host computer can assist the measurement system to complete the high-voltage power supply discharge status monitoring and fault location analysis.

[0048] Specific as Figure 1 The digital control system shown controls and monitors the high-voltage power supplies of the four auxiliary heating systems, namely, electron cyclotron, neutral beam, ion cyclotron, and low-noise. Each auxiliary heating system includes a power supply host computer and multiple controllers to realize the drive control and monitoring of multiple high-voltage power supply modules. The system includes clients corresponding to the four auxiliary heating systems (i.e., ECRH client, NBI client, ICRH client, and LHCD client), servers, a central control system, power supply host computers in the four auxiliary heating systems (i.e., NBI (HVPS), ECRH (HVPS), LHCD (HVPS), and ICRH (HVPS)) and a data management center, multiple controllers (controller 1, ..., controller x), and photoelectric conversion modules and high-voltage power supply modules corresponding to each controller. The clients corresponding to the four auxiliary heating systems, servers, central control systems, power supply host computers corresponding to the four auxiliary heating systems, and data management centers are networked to realize data interaction. The client, server, central control system, and power supply host computer use the server as a data transmission bridge to realize data interaction at the service layer. It should be noted that Figure 1 This is only an exemplary description and does not limit the type and number of auxiliary heating systems in the digital control system. That is, in other optional implementations, other types or numbers of auxiliary heating systems' power supply host computers, clients and central control systems may be networked and interacted, as long as they are implemented in the above-mentioned networking interaction manner.

[0049] like Figure 2 As shown, there are three types of data interactions among the client, power supply host computer, central control system, server, and controller: discharge parameter data stream of the central control system EPIC server, control-related parameter data stream, and file parameter data stream.

[0050] Among them, the implementation process of the discharge parameter data flow of the central control system EPIC server is specifically as follows: the server reads the discharge gun number and other related discharge parameters stored in the EPIC server, and the client and the power supply host computer then obtain the discharge gun number and other related discharge parameters through the server. The data interaction between the central control system and the power system side only occurs between the central control system and the server. The data interaction coupling is small, and the networking and isolation links between the power system side and the central control system are simple.

[0051] The specific implementation process of the control-related parameter data flow is as follows: the transmission of control parameters has two modes: power supply host computer and client control. When client control is selected, the control parameters are transmitted to the power supply host computer through the server. The power supply host computer automatically packages the corresponding control values ​​and certain control data of the power supply host computer according to the value change and other attributes of the read value, and transmits them to the specific corresponding controller after being parsed by the data management center. The controller can also return the corresponding control data to the power supply host computer and the client for data verification; when the power supply host computer control is selected, the control data set by the host computer is directly transmitted to the data management center through the power supply host computer, and after being parsed by the data management center, it is passed to the specific corresponding controller. The controller can also return the corresponding control data to the power supply host computer for data verification.

[0052] The specific implementation process of the file parameter data flow is as follows: the controller collects the voltage, current and status data of the high-voltage power supply module and transmits it to the power supply host computer for real-time display, and saves the data during discharge with "gun number + device name" as the file name. The stored data is backed up and stored in the server, central control system and client in the form of files, and the discharge data is visualized on the client and central control system.

[0053] This embodiment also proposes a control method based on the above-mentioned high-voltage power supply digital control system, such as Figure 3 As shown, the specific process of the control method is as follows:

[0054] Step 1: select the corresponding high-voltage power supply control system according to the auxiliary heating type, connect the corresponding systems through the network, and realize the connectivity of the data link.

[0055] Step 2, determine the power user, grant parameter control rights to the client or the power host computer through the power host computer, and obtain the discharge parameters stored in the central control system EPIC server through the server.

[0056] Step 3, when client control is selected, the control parameters are transmitted to the power supply host computer through the server. The power supply host computer automatically packages the corresponding control values ​​with certain control data of the power supply host computer according to the value change and other attributes of the read value, and transmits them to the corresponding controller after being parsed by the data management center; when power supply host computer control is selected, the control parameters are set and packaged directly through the power supply host computer, and are transmitted to the corresponding controller after being parsed by the data management center; optionally, the controller can also transmit the corresponding control data back to the power supply host computer for data verification.

[0057] Step 4: The controller waits for the timing signal from the central control system and other systems, sends a driving signal through the photoelectric conversion module to control the operation of the high-voltage power supply module, and provides feedback to adjust the output value of the high-voltage power supply module.

[0058] Furthermore, the control method further includes:

[0059] Step 5, monitor the protection signal of the system, and determine whether to block the drive and turn off the power output according to the protection signal status.

[0060] Furthermore, the control method further includes:

[0061] Step 6: monitor the status, voltage value, current value and control signal status of the high-voltage power supply module in real time, store and back up the data during discharge in the power supply host computer, server, client and central control system in accordance with the unified data format of the central control system, and realize the visualization of relevant discharge data.

[0062] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the present application in detail. It should be understood that the above description is only the specific implementation method of the present application and is not intended to limit the scope of protection of the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
