Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of converters, in particular to a real-time intelligent control hub system based on a GPPC series open converter. BACKGROUND

[0002] The traditional power electronics teaching platform has significant system faults and functional defects in the technical dimension of "host computer monitoring and control". The following analyzes the current situation:

[0003] 1. The status and defects of the host computer monitoring function: data acquisition is closed, and the configurability is poor. The host computer software of the traditional platform is mostly a closed system, only supporting the static display of basic data (voltage, current, etc.), and cannot customize the data list of remote measurement points (YC) and remote signaling points (YX). Students cannot practice industrial-level operations such as Modbus data point editing and communication device table configuration, resulting in a hollow understanding of smart grid data flow architecture.

[0004] The monitoring interface is fixed and cannot be configured as needed. For example, students cannot dynamically generate a primary system diagram or real-time curve through the configuration software, limiting the development of fault analysis capabilities.

[0005] 2. The status and defects of the host computer control function: the host computer control instructions (such as PWM wave issuance and circuit breaker opening and closing) are presented in the form of "button operation", and students cannot view or modify the underlying logic. The control instructions are disconnected from the device response. For example, after the host computer sends a PWM signal, students cannot track the dynamic response of the inverter circuit (such as waveform distortion caused by dead-time effect) in real time through the monitoring end.

[0006] 3. System-level collaboration and scalability defects: the host computer system of the traditional platform lacks bidirectional data mapping with physical devices. For example, parameter modifications in virtual simulation (such as adjusting PID coefficients) cannot be synchronized in real time to the physical inverter, and students cannot experience the "design-simulation-deployment" closed loop. The host computer software has poor compatibility and does not support API integration with third-party platforms (such as Python data analysis libraries and MATLAB control algorithm libraries).

[0007] The host computer monitoring and control function of the traditional power electronics teaching platform has three shackles of "data closure, logic black box, and virtual-real split", which prevents students from deeply practicing core skills of industrial-level monitoring systems (such as protocol development, data point configuration, and cloud-edge collaboration). Breaking through this requires an open architecture as the foundation, integrating dynamic mode switching and digital twin verification, to cultivate complex talents that meet the needs of smart grids. SUMMARY

[0008] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a real-time intelligent control hub system based on the GPPC series open converter, which solves the problem that the host computer monitoring and control functions of traditional power electronics teaching platforms have three constraints: "data closure, logic black box, and virtual-real separation", which prevent students from deeply practicing the core skills of industrial-grade monitoring systems.

[0009] To achieve the above and other related objectives, the present invention provides the following technical solution:

[0014] In one embodiment of the present invention, the first core control submodule includes a MicroLabBox and a MicroLabBox SAB system, which are used to control and process signals of the GPPC series open converter according to the programmed program.

[0015] In one embodiment of the present invention, the first monitoring submodule is ControlDesk software. A configuration model is established in the ControlDesk software, and each display module and control module are defined according to the model in the MATLAB or SIMULINK simulation software. Through the display module and control module, the outputs of each analog quantity, digital quantity and PWM module of the GPPC series open converter can be monitored and controlled in real time.

[0016] In one embodiment of the present invention, the second core control submodule includes RT-Module and RT-Module SAB devices, which are used to control and process signals of the GPPC series open converter according to the programmed program.

[0017] In one embodiment of the present invention, the second monitoring submodule is imperix Cockpit software. Various display modules and control modules are established in the imperix Cockpit software. Through the display modules and control modules, the state variables of the GPPC series open converter can be monitored in real time and the output of control variables can be controlled in real time.

[0018] In one embodiment of the present invention, the RT-Module and RT-Module SAB devices are connected to the GPPC series open converter through a signal processing and conversion module. The RT-Module and RT-Module SAB devices are connected to the signal processing and conversion module through an interface unit. The interface unit is connected to the output terminal of the RT-Module and RT-Module SAB devices and to the input terminal of the signal processing and conversion module. The interface unit includes several connectors.

[0019] As described above, the real-time intelligent control hub system based on the GPPC series open converter of the present invention has the following beneficial effects: The present invention enables students or researchers to independently design control systems through MATLAB / SIMULINK and the GPPC series open converter, adjust circuit parameters (such as duty cycle and load resistance) in real time, observe the operating status of switching devices, and the changes in analog waveforms such as current / voltage / active power, and intuitively understand the working principle or SPWM modulation process of various topologies such as Buck / Boost converters, three-phase full-bridge inverters, and H-bridge inverters;

[0026] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features described herein can be combined with each other.

[0027] Please see Figures 1 to 5 The present invention provides a real-time intelligent control hub system based on GPPC series open converters, including a first intelligent control module and a second intelligent control module. The first intelligent control module includes a control method design submodule, a first core control submodule and a first monitoring submodule. The first core control submodule and the first monitoring submodule are both connected to the GPPC series open converter.

[0028] The control method design submodule is a MATLAB or SIMULINK simulation software. In the MATLAB or SIMULINK simulation software, the user establishes a corresponding topology model and a suitable control method model based on the main circuit topology in the GPPC series open converter. The topology model and control method model established in the MATLAB or SIMULINK simulation software are compiled, and communication with the first core control submodule is established via Ethernet. The compiled program is then burned into the first core control submodule.

[0029] The first core control submodule includes the MicroLabBox and MicroLabBox SAB systems, which are used to control and process signals of the GPPC series open converters according to the programmed program. The first monitoring submodule is the ControlDesk software, in which a configuration model is built and various display modules and control modules are defined according to the model in MATLAB or SIMULINK simulation software. Through the various display modules and control modules, the output of various analog quantities, digital quantities and PWM modules of the GPPC series open converters can be monitored and controlled in real time.

[0030] Specifically, using MATLAB / SIMULINK simulation software, a corresponding topology model and a suitable control method model (which can be designed by the user) are established based on the main circuit topology of the GPPC series open converter. The output channel number and input channel number of each analog quantity are defined through the connection paths of each port of MicroLabBox and MicroLabBox SAB to the GPPC series open converter, the output channel number and input channel number of each digital quantity are defined, and the output channel of each PWM wave is defined.

[0031] The MATLAB / SIMULINK model is compiled, an Ethernet network is established and an IP address is matched, communication with MicroLabBox is established, the compiled program is burned into MicroLabBox, and MicroLabBox and MicroLabBox SAB are used to control and process signals of the GPPC series open converter. A configuration model is established in ControlDesk, and each display module and control module is defined according to the model in MATLAB / SIMULINK, so that the ControlDesk software can play a role similar to a host computer, and can monitor and control various analog quantities (DC voltage VDC, DC current IDC, three-phase current IU, IV, IW, temperature TEMPT) and digital quantities (enable signal ENABLE1, PWM wave stop signal, RST-PWM1, relay SHOT-1, and over-temperature and over-current fault signals such as OV1 and OT1) of the GPPC series open converter in real time. The PWM module output (for the three-phase full-bridge IGBT structure, a total of 7 PWM waves can be output, of which six control the three-phase full-bridge output and one controls the braking switch action).

[0032] The second intelligent control module also includes a control method design submodule, a second core control submodule, and a second monitoring submodule. Both the second core control submodule and the second monitoring submodule are connected to the GPPC series open converter. The second core control submodule includes RT-Module and RT-Module SAB devices, which are used to control and process signals of the GPPC series open converter according to the programmed program. The RT-Module and RT-Module SAB devices are connected to the GPPC series open converter through the signal processing and conversion module. The RT-Module and RT-Module SAB devices are connected to the signal processing and conversion module through an interface unit. The interface unit is connected to the output terminal of the RT-Module and RT-Module SAB devices and to the input terminal of the signal processing and conversion module. The interface unit includes several connectors.

[0033] The second monitoring submodule is the imperix Cockpit software. Various display modules and control modules are built in the imperix Cockpit software. Through the display modules and control modules, the status variables of the GPPC series open converter can be monitored in real time and the output of control variables can be controlled in real time.

[0034] Specifically, in addition to using ControlDesk software to achieve real-time monitoring and real-time control output functions, the GPPC series open converter is also compatible with imperix Cockpit software. The technical solution is similar to the above, defining the output channel number and input channel number of each analog quantity, the output channel number and input channel number of each digital quantity, and the output channel of each PWM wave through the connection path of each port of the RT-Module and RT-Module SAB device to the GPPC series open converter.

[0035] The above MATLAB / SIMULINK model is compiled, an Ethernet network is established and an IP address is matched, communication with the RT-Module device is established, the compiled program is burned into the RT-Module device, and the RT-Module and RT-ModuleSAB devices are used to control and process signals of the GPPC series open converter. After establishing various display modules and control modules using the imperix Cockpit software, the status variables of the GPPC series open converter are monitored and the output of control variables is controlled in real time.

It directly connects to and manages the two key lower-level modules.

[0037] Power Drive and Safety Layer (Middle): There are two main functional modules, SA-ISO and GPPC, side by side, both controlled by RT_Module; SA-ISO (Safe Amplified Power): This is the key signal processing and conversion module. It receives PWM (Pulse Width Modulation) control signals and I / O signals from RT_Module. Its core function is to safely amplify low-power control signals to drive actuators. It includes multiple safety monitoring functions (FAULT, voltage, current, temperature) to ensure safe shutdown in abnormal situations; GPPC: This is the main power control module. It is directly connected to the power source (Electrical Source (AC or DC)) and is responsible for converting the input AC or DC power into a controllable three-phase (U, V, W) output. It is typically used to drive the main motor or actuator. It also includes status monitoring (FAULT, voltage, current, temperature).

[0038] Execution and Communication Layer (Right Side): Electrical Source: The system's main power input (AC or DC); U, V, W: Power output terminals of SA-ISO and GPPC modules, typically connected to motors or other actuators; CAN: Controller Area Network bus, used for reliable, real-time data communication between modules or with external devices (such as encoders, sensors, and other controllers); D / A (Digital to Analog): A digital-to-analog converter that converts digital control signals (from devices such as RT_Module) into analog signals, which may be used to control analog instruments, valves, or other devices that require analog input.
