Description

Technical Field

[0001] This invention relates to the field of ring network switchgear technology, specifically to integrated primary and secondary ring network switchgear and control system. Background Technology

[0002] With the deepening of the construction of smart grids and new power systems, integrated primary and secondary ring network switchgear, as a key node in the distribution network, has seen its intelligence, environmental friendliness, high reliability, and ability to coordinate with distributed energy sources become core development requirements. However, existing equipment and its control systems have significant shortcomings in the following aspects, which restrict the improvement of overall performance.

[0003] Currently, traditional ring network switchgear faces systemic bottlenecks and contradictions in technology: It commonly uses environmentally hazardous insulation materials such as SF6 gas or epoxy resin; the primary and secondary equipment employ separate designs and non-standard interfaces, resulting in poor environmental performance, difficulties in compatibility between components from different manufacturers, and hindering the stable and efficient acquisition of primary-side electrical parameters. Its level of intelligence is limited; intelligent units often operate in isolation, lacking edge computing deep analysis capabilities based on multi-source information and cross-device collaborative decision-making capabilities. This makes it difficult to achieve accurate fault warnings and support complex applications, and also hinders its ability to proactively adapt to complex outdoor environments, highlighting the contradictions between insulation, sealing, and corrosion prevention. Furthermore, the monitoring, diagnosis, and decision-making processes are disconnected; operational data is difficult to translate into maintenance knowledge, relying on manual experience and periodic inspections, easily leading to over-maintenance or neglect, resulting in high maintenance costs and low efficiency.

[0038] Compared with existing technologies:

[0039] 1. A hierarchical control architecture of "local precise perception - regional collaborative decision-making - reliable closed-loop execution" has been systematically constructed, which fundamentally solves the core bottleneck of existing equipment being isolated in intelligence and lacking collaborative capabilities;

[0040] Traditional equipment's intelligent functions are limited to single-point protection, and information silos prevent regional optimization. This invention, through an original modular design, organically combines the edge computing intelligence of the secondary intelligent measurement and control module (achieving millisecond-level fault identification and load analysis) with the multi-agent collaborative decision-making of the distributed collaborative interaction module (achieving load balancing, renewable energy consumption, and collaborative fault recovery). Furthermore, a closed-loop control execution module and an environmental adaptation module ensure the safe, reliable, and adaptive execution of commands. This architecture transforms individual devices from information silos into intelligent network nodes capable of real-time interaction and collaborative optimization, thus achieving a qualitative leap from single-point automation to collective intelligence. This significantly improves the power supply reliability, operational economy, and capacity to accommodate distributed energy resources in the power distribution network.

[0041] 2. It has established a complete operation and maintenance data chain, from "data collection to status assessment to intelligent decision-making," enabling a fundamental shift in the operation and maintenance model from passive response to proactive prediction.

[0042] With the addition of an intelligent operation and maintenance management module, the massive amounts of operational, collaborative, and environmental data generated by the aforementioned modules can be deeply integrated and analyzed. By constructing a multi-dimensional health assessment model, the system can automatically generate accurate health scores and pre-maintenance plans, and achieve seamless collaboration with operation and maintenance personnel through remote linkage units. This allows operation and maintenance work to be based on the actual condition of the equipment rather than fixed cycles, effectively avoiding over-maintenance and under-maintenance, and upgrading the operation and maintenance mode from traditional manual inspection and reactive repair to predictive maintenance and precise inspection, thereby significantly reducing the risk of unplanned power outages and overall operation and maintenance costs.

[0051] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0052] This invention provides a control system for a primary and secondary integrated ring network switchgear. Please refer to [link / reference]. Figure 1 ,include:

[0053] The primary equipment integration module, as the core physical carrier and basic support of the equipment, is based on environmentally friendly dry air insulation and integrated switch design. It is equipped with standardized adaptive connection interface, which not only solves the environmental hazards and sealing problems of traditional media, but also achieves compatibility of components from multiple manufacturers. At the same time, it collects primary side power parameters to provide a stable operating environment and primary side raw data for subsequent modules.

[0054] The secondary intelligent measurement and control module undertakes the core responsibilities of data processing and precise measurement and control. It integrates primary side parameters and environmental auxiliary information through multi-source data acquisition, and realizes fault identification, load analysis and parameter diagnosis through edge computing algorithms. It also generates control commands that conform to the constraints of primary equipment. At the same time, relying on standardized communication protocols, it opens up data transmission channels across modules, forming a complete logical chain of acquisition-analysis-decision-output.

[0055] The distributed collaborative interaction module focuses on cross-dimensional collaborative decision-making. Through cross-device data interaction compatible with multiple protocols, it integrates the status of adjacent devices, distributed energy output and grid dispatch instructions, and optimizes decision-making schemes based on multi-agent algorithms. At the same time, it transforms macro-level collaborative strategies into priority instructions that can be executed by devices, realizing the organic integration of single device control and source-grid-load-storage coordination.

[0056] The closed-loop control execution module accurately responds to the adaptation instructions of the distributed collaborative interaction module, and completes tripping and closing, insulation pressure regulation and fault circuit isolation actions through the linkage of three-level units: switch drive, insulation adjustment and fault isolation. At the same time, the action process is fed back to the preceding module in real time to ensure that the control instructions are safely implemented and to ensure that the equipment operation status is stable and controllable.

[0057] The environment adaptive module accurately collects environmental parameters through environmental sensing and dynamically activates the protection mechanism based on the operating characteristics of the preceding module. At the same time, it links the sealing enhancement function to adapt to the environmental differences of different application scenarios and resolve the performance contradiction between corrosion prevention, sealing and insulation of equipment in outdoor environments.

[0058] The intelligent operation and maintenance management module enables intelligent control of the entire equipment lifecycle. It integrates the operating data and environmental information fed back by various modules, builds a multi-dimensional health assessment model, and generates accurate maintenance plans. At the same time, it synchronizes the data to the control center and operation and maintenance terminals through a remote linkage mechanism, thus opening up the link between status assessment, maintenance decision-making and remote collaboration, reducing operation and maintenance costs and improving maintenance efficiency.

[0059] Please see Figure 2 The primary equipment fusion module includes:

[0060] The environmentally friendly insulation unit uses dry air as the insulation medium and is equipped with a BMC material frame and a DMC material spindle, reducing the amount of epoxy resin used (environmentally friendly materials account for ≥95%), solving the environmental hazards of traditional SF6 gas and the problem of non-degradability of epoxy resin; and through the sealed structure design, it achieves an IP67 protection level, providing a stable operating environment for subsequent units.

[0061] The integrated switch unit combines a three-position disconnector, a vacuum circuit breaker, and a current transformer. It adopts a three-phase integrated design to improve the consistency of the disconnector. The current transformer has an accuracy class of 0.5 and can collect voltage and current data in real time, providing the original data source for the secondary intelligent measurement and control module.

[0062] The adaptive connection unit is equipped with a standardized pluggable interface to be compatible with primary equipment components from different manufacturers. The interface has built-in mechanical and electrical interlocking mechanisms to ensure the correct wiring when connecting to the secondary intelligent measurement and control module. Its interface parameters are automatically generated by matching the dielectric type of the insulation unit and the rated parameters of the switch unit.

[0063] Please see Figure 3 The secondary intelligent measurement and control module includes:

[0064] The multi-source data acquisition unit receives voltage and current data from the primary equipment fusion module through a standardized interface, and simultaneously acquires auxiliary parameters such as ambient temperature and humidity, equipment temperature rise, and partial discharge. The sampling frequency reaches 10kHz, and the data transmission delay is ≤10ms, providing comprehensive data input for subsequent analysis units.

[0065] The intelligent analysis unit uses edge computing algorithms to process data transmitted from the multi-source data acquisition unit in real time, including load trend analysis, fault type identification (short circuit / overload / insulation aging), and parameter deviation diagnosis. Its analysis model is dynamically optimized based on historical and real-time data from the acquisition unit.

[0066] The decision control unit generates control commands based on the output of the intelligent analysis unit. For example, when a phase-to-phase short circuit is detected, a trip command is immediately triggered; when the load exceeds 80% of the rated value, a load adjustment suggestion is issued. The command generation must meet the rated parameter constraints of the primary equipment fusion module (such as short-time withstand current ≤20kA).

[0067] The standardized communication unit adopts a PROFINET / HART dual protocol stack to synchronize analysis results and control commands to subsequent modules. The communication interface is compatible with the IEC61850 standard to ensure the consistency of data transmission across modules.

[0068] Please see Figure 4 The distributed collaborative interaction module includes:

[0069] The cross-device data interaction unit, based on the standardized communication unit of the secondary intelligent measurement and control module (compatible with IEC61850 and PROFINET / HART protocols), bidirectionally exchanges three types of data; it receives the operating status (load, fault risk) of adjacent ring network equipment, the output data of distributed energy (photovoltaic power, energy storage SOC), and the load control instructions from the power grid dispatch center, while uploading the secondary analysis results (load trend, health status) of this device, providing multi-source data support for collaborative decision-making, with a data transmission delay of ≤20ms to ensure real-time performance;

[0070] The collaborative decision-making optimization unit employs a multi-agent collaborative algorithm. Its core optimization objectives include, but are not limited to, minimizing network losses, balancing regional loads, efficiently absorbing distributed energy, and rapidly isolating faults and restoring power supply. Based on the intelligent analysis results of the secondary intelligent measurement and control module (fault identification of this equipment and load deviation diagnosis), and combined with external data from the cross-equipment data interaction unit, it generates collaborative control strategies. For example, when the load of this equipment exceeds the rated value by 80%, it coordinates adjacent equipment to share the load; when the output of distributed energy suddenly increases, it adjusts the switching status of this equipment to adapt to absorption; when a fault occurs in a certain area, it links with surrounding equipment to quickly isolate the faulty area and restore power supply to the non-faulty areas. The decision-making process must meet the rated parameter constraints of the primary equipment fusion module (such as rated voltage and short-time withstand current).

[0071] The instruction adaptation unit transforms the macro-strategy of the collaborative decision optimization unit into specific control instructions that conform to the hardware capabilities of the device. It also eliminates instructions that exceed the capacity of the primary equipment fusion module (such as tripping instructions that exceed the breaking capacity of the switch unit). At the same time, it prioritizes the collaborative instructions and the single-device control instructions of the secondary intelligent measurement and control module (fault instructions > collaborative load instructions > routine adjustment instructions) to ensure the safety and feasibility of the instructions. Finally, it outputs the instructions to the closed-loop control execution module.

[0072] Please see Figure 5 The closed-loop control execution module includes:

[0073] The switch drive unit receives trip / close commands (including commands generated by collaborative decision-making) from the command adapter unit and uses an electric energy storage spring operating mechanism with a response time of ≤50ms to drive the integrated switch unit of the primary equipment fusion module to complete the action. The action result is fed back to the decision control unit and the collaborative decision optimization unit in real time.

[0074] The insulation adjustment unit automatically adjusts the dry air charging pressure (adjustment range 0.01-0.03Mpa) based on the partial discharge data from the intelligent analysis unit. When a drop in insulation level is detected, the air replenishment device is activated to ensure that the insulation performance meets the operating requirements of the primary equipment fusion module.

[0075] When the decision control unit identifies a serious fault, the fault isolation unit works in conjunction with the switch drive unit to immediately disconnect the connection between the fault circuit and the non-fault circuit after the fault current is cut off, and at the same time generate a fault isolation signal to provide clear fault location information for the operation and maintenance module.

[0076] Please see Figure 6 The environment adaptive module includes:

[0077] The environmental sensing unit collects data such as temperature, humidity, salt spray concentration, and dust content of the equipment's operating environment, with a data accuracy of ±0.5℃ (temperature) and ±5%RH (humidity), providing environmental parameter support for the adaptive adjustment unit;

[0078] The adaptive adjustment unit activates corresponding protection mechanisms based on data from the environmental sensing unit. For example, when the salt spray concentration exceeds the standard, it activates the anti-corrosion coating heating and demisting device; when the temperature exceeds 40°C, it links the heat dissipation system of the primary equipment fusion module to increase the heat dissipation power. The adjustment logic needs to match the insulation characteristics of the primary equipment fusion module with the operating parameters of the secondary intelligent measurement and control module.

[0079] The sealing reinforcement unit controls the pre-tightening torque of the seal (adjustment range 20-50 N•m) according to the instructions of the adaptive adjustment unit, and adopts a double-layer sealing structure to prevent media leakage, ensuring the sealing performance of the environmentally friendly insulation unit. Its pre-tightening force is dynamically optimized according to the ambient humidity data.

[0080] Please see Figure 7 The intelligent operation and maintenance management module includes:

[0081] The status assessment unit receives the analysis results from the secondary intelligent measurement and control module, the sensing data from the environmental adaptation module, and the collaborative operation data from the distributed collaborative interaction module. It then establishes an equipment health assessment model to generate a health score (0-100 points) from four aspects: insulation performance, mechanical life, electrical parameters, and collaborative adaptability. The score data is directly linked to the maintenance decision unit.

[0082] The maintenance decision unit automatically generates maintenance plans based on the health score of the status assessment unit. If the score is below 60, emergency maintenance is triggered. If the score is between 60 and 80, a regular maintenance reminder is generated. The plan includes the model of the component to be replaced (based on the interface standard of the primary equipment fusion module) and the maintenance process (matching the measurement and control requirements of the secondary intelligent measurement and control module).

[0083] The remote linkage unit synchronizes maintenance decisions, equipment status, and fault information to the power control center and operation and maintenance terminals, and supports remote parameter configuration and fault reset. For example, after receiving maintenance reminders via mobile devices, operation and maintenance personnel can obtain the primary equipment fusion module parameters, secondary intelligent measurement and control module analysis reports, and collaborative operation records in advance, thereby improving maintenance efficiency.

[0084] A primary and secondary integrated ring network switchgear includes a cabinet, wherein the cabinet is equipped with the control system of the aforementioned primary and secondary integrated ring network switchgear.

[0085] In practical use, the steps are as follows:

[0086] S1, Data Acquisition and Sensing: The primary equipment fusion module collects electrical parameters such as voltage and current on the primary side of the power grid in real time, and transmits the data stably to the secondary intelligent measurement and control module through the adaptive connection unit; at the same time, the environmental adaptive module is activated to continuously monitor parameters such as temperature, humidity, and salt spray concentration of the operating environment;

[0087] S2, Local Intelligent Analysis and Decision-Making: The multi-source data acquisition unit of the secondary intelligent measurement and control module receives primary side and environmental data; the intelligent analysis unit performs real-time load analysis, fault identification (such as short circuit, overload) and status diagnosis based on edge computing algorithms; the decision control unit generates preliminary control commands (such as tripping, alarm) that meet the capacity constraints of this equipment based on the analysis results.

[0088] S3, Regional Collaborative Decision-Making and Command Fusion: The distributed collaborative interaction module obtains the status of adjacent devices, distributed energy output, and superior scheduling commands through the cross-device data interaction unit. The collaborative decision-making optimization unit uses a multi-agent algorithm, combined with local analysis results, to form regional optimization strategies (such as load transfer and collaborative absorption); the command adaptation unit converts this strategy into specific commands executable by the device, performs security verification and priority sorting with the local commands generated by S2, and outputs the final set of execution commands.

[0089] S4, Closed-loop execution and status feedback: The closed-loop control execution module receives the execution command set and drives the switch drive unit, insulation adjustment unit and fault isolation unit to complete the corresponding physical actions (opening and closing, pressure regulation, circuit isolation); all action results are fed back to the secondary intelligent measurement and control module and the distributed collaborative interaction module in real time to form closed-loop control, ensuring that the commands are accurately implemented and the equipment status is controllable.

[0090] S5, Environmental Adaptive Adjustment: Throughout the entire operation of the equipment, the environmental adaptive module dynamically controls the adaptive adjustment unit and the sealing reinforcement unit based on the data from the environmental sensing unit, and activates or adjusts protective mechanisms such as heating, heat dissipation, and sealing pre-tightening force to ensure the stable insulation, sealing, and heat dissipation performance of the equipment under different environments.

[0091] S6, Intelligent Operation and Maintenance and Health Management: The intelligent operation and maintenance management module continuously collects operational data, collaborative data, and environmental data from S2, S3, and S5. The status assessment unit comprehensively calculates the equipment health score, and the maintenance decision unit generates early warnings or maintenance plans based on this. These plans are then synchronized to operation and maintenance personnel and the dispatch center via the remote linkage unit, supporting remote viewing, configuration, and collaborative maintenance, thus achieving intelligent management of the entire equipment lifecycle.

[0092] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
