Description

TECHNICAL FIELD

[0002] Under the background of energy low-carbon transformation and power market opening, new power systems need to have the ability of dynamic response, resilience guarantee and collaborative efficiency. The deployment efficiency and safety of new power load management systems, which are the key support for the safe operation of power grids, are crucial. However, there are significant pain points in the installation and debugging of current load management systems:

[0003] Firstly, the debugging process is heavily dependent on real power equipment such as circuit breakers, current / voltage transformers, etc. These devices are bulky, heavy, and require multiple people to carry and wire, which is time-consuming and labor-intensive. More importantly, live debugging on real equipment poses a high risk of electric shock.

[0004] Secondly, when verifying control strategies (such as split-field tripping and over-current protection), real power loads need to be connected. The power fluctuations of real loads can easily cause local grid voltage / frequency fluctuations, and in extreme cases, may lead to unplanned power outages. At the same time, real load parameters are difficult to adjust in real time, and cannot flexibly simulate multiple test scenarios such as light load, full load, and overload.

[0005] Thirdly, different manufacturers' load management terminals use fragmented communication protocols (such as Modbus-RTU, DL / T645-2007, and IEC 61850). Debugging personnel need to configure protocols and write test scripts for each type of terminal. The protocol adaptation of a single terminal takes several hours, and protocol compatibility issues hinder the collaborative debugging of multiple brands of terminals, greatly extending the overall system commissioning period.

[0039] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0040] Please refer to Figure 1 The embodiment of the present application provides a virtual load and multi-protocol adaptation based load management system integrated installation and debugging auxiliary component, which specifically comprises the following components:

[0041] Firstly, the fixed machine shell 1 is used as the physical support structure of the entire auxiliary component, and provides a stable installation environment for the internal modules.

[0042] Secondly, the AC power supply module 2 is arranged in the internal space of the fixed machine shell 1. The main function of the module is to generate adjustable three-phase AC power to simulate the working state of the virtual load. In the implementation, the module integrates a DSP chip and an IGBT power module, and adopts a voltage and current sampling feedback PID closed-loop control technology to ensure that the output three-phase AC power can accurately simulate the actual load characteristics.

[0043] Further, there is a load management terminal module 3, which is arranged on the external surface of the fixed cabinet 1 for convenient operation and connection. Its core function is to provide installation and connection interface for at least one load management terminal, ensuring that the load management terminal can stably interact with the auxiliary components.

[0044] In addition, there is a branch device module 4, which is also located in the internal part of the fixed cabinet 1. It is equipped with analog input interface and switching value input / output interface, which can simulate the signal monitoring and control function of the branch device in actual operation, and provide a more realistic environment for the debugging of the load management system.

[0045] The intermediate relay module 5 is also integrated in the internal part of the fixed cabinet 1 and is electrically connected with the branch device module 4. Its main responsibility is to receive commands from the control system and drive the circuit breaker to simulate corresponding actions, thereby realizing remote control and debugging of the load management system.

[0046] The load indication module 6 is arranged on the external surface of the fixed cabinet 1 for real-time observation by the operator. This module can display the running state of the virtual load in real time and issue an alarm signal in time when an abnormal situation is detected, ensuring the safety and reliability of the debugging process.

[0047] Finally, there is a protocol adaptation module 7, which is located in the internal part of the fixed cabinet 1 and is in communication connection with the load management terminal module 3. Its unique feature is that it can automatically identify and adapt to the communication protocols used by load management terminals of different manufacturers, thereby realizing seamless connection with various types of load management terminals.

[0048] Compared with the prior art, the load management system integrated installation and debugging auxiliary component based on virtual load and multi-protocol adaptation provided by the present application has the following remarkable beneficial effects:

[0049] In terms of safety benefits, the auxiliary component completely eliminates the risk of electric shock and power grid fluctuation by using virtual load technology, making single-person operation possible, thereby significantly improving the safety of the debugging process.

[0050] In terms of efficiency benefits, the introduction of multi-protocol automatic adaptation function significantly shortens the debugging time of a single terminal from the original 4-6 hours to within 1 hour, thereby significantly shortening the overall period of system network access and improving the debugging efficiency.

[0051] In terms of skill benefits, the auxiliary component provides a more intuitive and realistic debugging environment for the operating personnel through full-process reproduction and visual operation, which helps to effectively improve the skill level and training efficiency of the operating personnel.

[0052] In terms of economic benefits, a single set of auxiliary components can replace multiple real devices, significantly reducing procurement and operation costs, and bringing significant economic benefits to enterprises.

[0053] In one embodiment of the present embodiment, the structure design of the fixed cabinet 1 is further optimized and refined. Specifically, the front panel area of the fixed cabinet 1 is carefully planned and laid out, and a standard rail is integrated. This standard rail design follows the industry's general specifications and standards, has high compatibility and universality, and can adapt to the installation needs of modules of various types and sizes.

[0054] On this basis, the load management terminal module 3, the branch device module 4, and the intermediate relay module 5 all adopt an installation method that matches the standard rail. These modules can be easily and stably detached and installed on the standard rail through the cleverly designed elastic buckle structure. The design of the elastic buckle structure not only ensures the stability and reliability of the modules after installation, effectively preventing the modules from loosening or falling off due to vibration or external forces; at the same time, this detachable installation method also greatly improves the replacement and maintenance efficiency of the modules. When a module needs to be repaired, upgraded, or replaced, the operator only needs to press or pull the elastic buckle gently to quickly remove the module from the standard rail, without the need for complex tools or tedious operation steps, thereby greatly saving time and labor costs.

[0055] This design of detachably installing modules on the standard rail through the elastic buckle structure not only embodies the innovation and practicality of the present invention in structure design, but also provides a strong guarantee for the modularization, standardization, and convenient use of the load management system integrated installation and debugging auxiliary components.

[0056] In one embodiment of the present embodiment, the technical parameters and core components of the AC power supply module 2 are described in more detail and accurately. Specifically, the AC power supply module 2 has the following notable features in terms of electrical performance: its input power specification is single-phase AC 220V, which fully considers the common power supply situation in actual application scenarios, ensuring stable access and operation of the module in normal environments. In terms of output, the module can provide adjustable output of three-phase AC 220V / 380V. This flexible and variable output characteristic enables the module to adapt to the diversified voltage needs of different load devices, whether it is a load that requires 220V or 380V voltage, the module can achieve precise power supply.

[0057] At the same time, in terms of voltage regulation accuracy, the AC power supply module 2 exhibits a very high level of control, with a voltage regulation accuracy of ±0.5%. This high-precision voltage regulation capability means that the module can maintain very high stability when outputting voltage, effectively avoiding potential damage to the load device caused by voltage fluctuations, thereby ensuring the safe and stable operation of the load device. In addition, the maximum output power of the module is 5kVA, which fully meets the power requirements of most load management systems during installation and debugging, providing strong power support for the smooth debugging of the system.

[0058] In the selection of core components, the AC power supply module 2 also embodies a high degree of professionalism and precision. The DSP chip specifically uses the TMS320F28335 model, which is known for its powerful digital signal processing capabilities and is mainly responsible for generating SPWM (Sine Pulse Width Modulation) signals in the module. By generating accurate SPWM signals, the DSP chip can achieve precise control over the output voltage waveform, ensuring the quality and stability of the output voltage.

[0059] The IGBT power module specifically uses the SKM100GB12T4 model, which has high switching frequency, low conduction loss, and excellent thermal stability. In the module, the IGBT power module, as a key component of power conversion and control, can efficiently convert input DC power into the required three-phase AC power and achieve output voltage regulation and stability through precise control. The choice of SKM100GB12T4 undoubtedly provides a solid hardware foundation for the high-performance operation of the AC power supply module 2.

[0060] In one embodiment of the present embodiment, the core components and intelligent identification mechanism of the protocol adaptation module 7 are described in more detail. Specifically, the core controller of the protocol adaptation module 7 is carefully selected and uses the STM32F407 chip with excellent performance. This chip has a powerful processing capability, rich peripheral interfaces, and high programmability, and is widely used in industrial automation control, providing a solid hardware foundation for the protocol adaptation module 7 to achieve complex and accurate protocol identification functions.

[0061] In the protocol identification process, the protocol adaptation module 7 innovatively uses a three-level identification logic of baud rate automatic scanning-protocol frame header matching-check bit verification. This logic design is progressive and interlocking, ensuring the accuracy and efficiency of protocol identification.

[0062] Firstly, in the baud rate automatic scanning phase, the STM32F407 chip will automatically scan the input signal one by one according to the preset baud rate range. This process does not require human intervention, and the chip can intelligently adjust its own receiving baud rate to match the baud rate settings adopted by different protocols, thereby ensuring the smooth progress of subsequent protocol identification.

[0063] Next, enter the protocol frame header matching phase. After successfully scanning the correct baud rate, the chip will start the frame header matching operation on the received data frame. Different communication protocols often have their own unique frame header identifiers, such as the Modbus-RTU protocol usually uses a specific address byte as the frame header, and the DL / T645-2007 protocol has its specified frame start symbol. The STM32F407 chip can accurately determine the protocol type of the current data by comparing the received data with the preset protocol frame header template.

[0064] Finally, in the check bit verification phase, the chip will perform check bit verification on the data frame whose protocol type has been identified. Check bits are an important mechanism in communication protocols to ensure the accuracy of data transmission. Different protocols may use different verification methods, such as parity check, CRC check, etc. The STM32F407 chip will automatically select the corresponding verification algorithm to verify the data frame according to the identified protocol type. Only when the check bit verification is passed, the chip will finally confirm the protocol type of the data frame and complete the protocol identification process.

[0065] Through this three-level identification logic, the protocol adaptation module 7 can automatically and accurately identify Modbus-RTU, DL / T645-2007, IEC 61850 and other common communication protocols. This function greatly improves the compatibility and universality of the load management system integrated installation and debugging accessories, making the accessory easily cope with the communication needs of different manufacturers and different models of load management terminals, providing a strong guarantee for the smooth installation and debugging of the load management system.

[0066] In one embodiment of the present embodiment, the function design and implementation details of the load indication module 6 are more comprehensively and deeply described. Specifically, the load indication module 6 adopts a highly integrated and intelligent design scheme in terms of load state indication and abnormal alarm.

[0067] The module first integrates LED indicators of multiple colors for indicating different load states. These LED indicators can intuitively and clearly reflect the current operating state of the virtual load through the combination of different colors and flashing frequencies. For example, a green LED light constantly on may indicate that the load is in a normal working state, a yellow LED light flashing may indicate that the load is in a light load or standby state, and a red LED light flashing may indicate that the load has an abnormal situation such as overload or failure. This design of distinguishing load states through color and flashing frequency not only improves the efficiency of information transmission, but also enables the operator to quickly and accurately determine the operating condition of the load.

[0068] In addition to the LED indicators, the load indication module 6 is also equipped with an audible and visual alarm. The audible and visual alarm combines the dual alarm methods of sound and light, and can timely send out a prominent alarm signal when the load has an abnormal situation to attract the attention of the operator. More importantly, the alarm threshold of the audible and visual alarm can be flexibly set according to actual needs. This means that the operator can customize the size of the alarm threshold according to different load types, working environments, and safety requirements, etc. For example, for some devices that are sensitive to load fluctuations, the alarm threshold can be set relatively low so that the alarm can be sent out in time when the load has a slight abnormality; while for some devices that have high tolerance to load fluctuations, the alarm threshold can be set relatively high to avoid unnecessary alarm interference.

[0069] By integrating LED indicators of multiple colors and an audible and visual alarm with a settable alarm threshold, the load indication module 6 realizes all-round and multi-level indication and alarm of the operating state of the virtual load. This design not only improves the safety and reliability of the integrated installation and debugging aid of the load management system, but also provides the operator with more convenient and efficient means of load state monitoring and abnormal handling. In actual application, the operator only needs to observe the color and flashing frequency of the LED indicator and listen to the alarm signal of the audible and visual alarm to quickly grasp the operating condition of the load and take appropriate handling measures in time when an abnormal situation occurs, thereby ensuring the stable operation of the load management system.

[0070] In one embodiment of the present embodiment, the integrated installation and debugging aid of the load management system further integrates a set of functional and complete debugging software. The software runs on the host computer platform and establishes a stable and reliable data connection with the protocol adaptation module 7 through wired (such as RS485, Ethernet, etc.) or wireless (such as Wi-Fi, Bluetooth, etc.) communication methods to realize remote debugging and monitoring functions. The following is a detailed description of the functional modules of the debugging software:

[0071] The first is the main control area, which serves as the core operation interface for debugging software and undertakes the overall control task of the power supply system and the debugging process. The specific functions include:

[0072] Power start-stop control: Through simple and clear buttons or switches, operators can easily start and stop the power supply of virtual load, ensuring the safety and controllability of the debugging process.

[0073] Debugging mode selection: Provide multiple preset debugging modes (such as no-load test, full-load test, step load test, etc.), and operators can quickly select the appropriate debugging mode according to actual needs to improve debugging efficiency.

[0074] Emergency stop function: In case of emergency during debugging, operators can immediately trigger the emergency stop button to quickly cut off the power supply, prevent accidents from expanding, and ensure personnel and equipment safety.

[0075] The second is the parameter configuration area, which provides operators with flexible setting functions for power output and communication protocol parameters, including:

[0076] Power output parameter setting: Allows operators to accurately set key parameters such as output voltage (such as three-phase AC 220V / 380V adjustable), output power (maximum 5kVA), etc. according to actual load requirements, ensuring the authenticity and accuracy of the debugging environment.

[0077] Protocol parameter configuration: For different manufacturers and different models of load management terminals, operators can set the corresponding communication protocol parameters (such as baud rate, data bits, stop bits, check bits, etc.) in the parameter configuration area to ensure seamless connection between the debugging software and terminal equipment.

[0078] The third is the state display area, which displays key information in the debugging process through an intuitive visual interface, helping operators quickly grasp the system status. The specific display content includes:

[0079] Real-time display of electrical parameters: Display the output voltage, current, power, etc. of the current power supply in numerical or graphical form to facilitate operators to monitor the power supply status.

[0080] Load state visualization: Display the current state of virtual load (such as normal operation, overload, fault, etc.) through a graphical interface, and combine the color change of LED indicator lights to provide more intuitive load state indication.

[0081] Alarm information prompt: When the system detects abnormal conditions (such as voltage fluctuation, overload, communication interruption, etc.), the state display area will immediately pop up an alarm window accompanied by sound and light alarm signals to remind operators to handle it in time.

[0082] The fourth is the data recording area, which is responsible for recording key data during the entire debugging process and providing data analysis and report generation functions, including:

[0083] Debugging data recording: automatically records debugging data such as power output parameters, load state changes, alarm events, etc., to ensure traceability of the debugging process.

[0084] Trend curve generation: generates trend curves of voltage, current, power, etc. over time based on recorded data to help operators analyze system performance and stability.

[0085] Report export function: supports exporting debugging data, trend curves, and analysis results into report files in formats such as PDF and Excel, making it easy for operators to organize, archive, share, or submit to relevant departments for review.

[0086] By integrating the above functional modules, the debugging software provides a powerful and convenient remote debugging and monitoring means for the integrated installation and debugging of load management system auxiliary components, significantly improving debugging efficiency and accuracy, and reducing debugging costs and risks.

[0087] In one embodiment of the present embodiment, the debugging software realizes highly intelligent functional expansion, particularly integrating an advanced AI fault diagnosis module. This module relies on deep learning and machine learning algorithms, and through deep mining and training of massive historical fault data, it constructs precise fault feature models and diagnostic logic. In actual operation, when the debugging software detects any abnormal signals or data fluctuations outside the normal range through real-time monitoring of system parameters and operating states, the AI fault diagnosis function will be activated immediately.

[0088] This function not only quickly locates the specific location and impact range of the fault, but also automatically and deeply analyzes the root cause of the fault based on the trained knowledge base and intelligent reasoning mechanism. The analysis process covers multiple dimensions such as hardware failure, software error, communication anomaly, and environmental interference, ensuring the comprehensiveness and accuracy of the diagnostic results.

[0089] Further, after determining the cause of the fault, the AI fault diagnosis function will immediately generate a detailed troubleshooting recommendation report. This report not only lists possible fault sources and corresponding solutions, but also provides priority ranking and step-by-step implementation guidelines based on the urgency and impact of the fault. In this way, even if the operator lacks deep professional knowledge, they can quickly and effectively complete fault location and repair work based on the clear instructions in the report, significantly shortening fault recovery time and improving the operational stability and reliability of the entire load management system.

[0090] In one embodiment of the present embodiment, the protocol adaptation module 7 is further optimized and expanded in terms of functional design, particularly integrating a high-performance 4G communication module. The introduction of this module endows the load management system integrated installation and debugging auxiliary with powerful remote communication capabilities, completely breaking the spatial and temporal limitations of traditional debugging methods.

[0091] Specifically, the integration of the 4G communication module enables the protocol adaptation module 7 to establish a seamless connection with the remote control center or upper computer software through a high-speed and stable 4G mobile communication network. Based on this connection, the debugging personnel can issue various debugging commands to the protocol adaptation module 7 through remote operation without being present on site. These commands cover a wide range of control instructions from power parameter adjustment, protocol configuration modification to debugging mode switching, ensuring the flexibility and efficiency of the debugging process.

[0092] Meanwhile, the 4G communication module also supports real-time data remote transmission function. During the debugging process, the protocol adaptation module 7 can collect and process various key data in real time, such as power output voltage, current, power, and load state, communication protocol interaction information, etc. These data are uploaded to the remote monitoring platform in a high-speed and reliable manner through the 4G network, enabling the debugging personnel to view the real-time running state of the system at any time and any place, and timely discover and handle potential problems.

[0093] In addition, the integration of the 4G communication module also greatly improves the collaboration and convenience of the debugging process. Multiple debugging personnel can simultaneously access the system through remote means for collaborative debugging and data sharing, thereby speeding up the debugging process and improving the debugging quality. At the same time, the function of remotely viewing real-time data also provides strong data support for the system acceptance and performance evaluation after debugging.

[0094] In summary, the protocol adaptation module 7, by integrating the 4G communication module, realizes the functions of remotely issuing debugging commands and viewing real-time data, bringing unprecedented convenience and efficiency to the load management system integrated installation and debugging auxiliary, and significantly improving the intelligent level of the debugging work.

[0095] Although the terms such as fixed casing and AC power module are used more in the present invention, the possibility of using other terms is not excluded. The use of these terms is only to facilitate the description and explanation of the essence of the present invention; any additional limitation is contrary to the spirit of the present invention.

[0096] Finally, it should be noted that the above embodiments have been described in the specification and drawings of the present application, but this does not limit the patent protection scope of the present application. Any equivalent structure or equivalent process replacement or modification based on the essential concept of the present application, using the content described in the specification and drawings of the present application, and directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of the present application.
