Description

Technical Field

[0001] This invention relates to the fields of power system automation and substation equipment maintenance technology, and in particular to methods, systems, equipment and media for integrated protection and uninterrupted power supply retrofitting of substation switchgear. Background Technology

[0002] With the continuous advancement of intelligent upgrades to power systems, the demand for updating integrated automation protection equipment in substations is becoming increasingly urgent. Currently, the industry generally adopts the traditional power outage operation mode for the renovation of integrated protection equipment that has exceeded its service life, which involves dismantling the old equipment and installing the new equipment while the equipment is out of service. Some technologies attempt to introduce transitional protection devices to shorten power outage time, but these still rely on complex secondary circuit disassembly and assembly and manual item-by-item verification, resulting in long renovation cycles and concentrated risks. Although existing technologies have achieved the auxiliary application of automated testing tools in some aspects, the integration of online testing and rapid switching technologies is insufficient, making it difficult to support the requirements of uninterrupted power outage renovation throughout the entire process.

[0003] Traditional upgrade methods require power outages, affecting power supply continuity and posing drawbacks such as high short-circuit risks during secondary circuit installation and removal, and low efficiency of manual verification. During equipment switching, the lack of standardized access modules and intelligent detection systems makes them prone to malfunctions due to wiring errors or signal inconsistencies, threatening grid safety. Furthermore, existing technologies lack sufficient support for pre-upgrade commissioning and installation logic verification, relying heavily on offline testing and manual intervention for on-site operations, resulting in low efficiency and unreliable performance. These issues hinder the rapid implementation of substation equipment upgrades and the safe and stable operation of the power grid, necessitating a highly efficient upgrade method integrating rapid switching, intelligent detection, and full-process risk control. Summary of the Invention

[0004] In view of the aforementioned existing problems, the present invention is proposed.

[0005] Therefore, this invention provides a method and system solution for the uninterrupted power supply retrofit of substation switchgear. It achieves seamless switching between old and new equipment through a quick, non-disassembly-free module connection. Combined with customized terminal blocks and an online detection logic view, it pre-positions and standardizes on-site wiring and commissioning work, reducing the risk of manual intervention and misoperation. Relying on transitional integrated protection equipment and an intelligent pre-commissioning system, it maintains uninterrupted protection functions throughout the entire retrofit process, effectively solving problems such as power outages caused by traditional power outage retrofits, safety hazards in secondary circuit disassembly and assembly, and low efficiency of manual verification. This ensures that power grid operation safety and retrofit efficiency are improved simultaneously.

[0053] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0054] Example 1, referring to Figure 1 As an embodiment of the present invention, a method for uninterrupted power supply retrofitting of substation switchgear is provided, comprising:

[0055] S1: Establish a fully covered simulation debugging platform to simultaneously carry out physical wiring and functional verification;

[0057] S3: Uses a first-level access mechanism to create and run the environment for the transition and dynamic management of new and old devices;

[0058] S4: Implement protection actions based on mirroring technology, triggering device security disconnection and collaborative scheduling.

[0059] It should be noted that existing substation renovation technologies have bottlenecks such as high risk of on-site commissioning errors, the need for power outages for switching between old and new equipment, strong reliance on manual labor, and lack of real-time verification of protection functions.

[0060] Therefore, to address the aforementioned issues of insufficient power supply continuity, low transformation efficiency, and weak safety management, the S1-S4 steps enable coordinated control of offline pre-verification and online dynamic migration, constructing a closed-loop transformation system that ensures continuous power supply to the system while completing equipment replacement and resource recovery, significantly improving the safety of transformation operations and the efficiency of project implementation.

[0061] Example 2, refer to Figures 1-6 As an embodiment of the present invention, based on the above embodiment, a method for uninterrupted power supply retrofitting of substation switchgear is provided.

After the new integrated protection device operates, it sends trip and close commands to the simulated circuit breaker device, thus completing the functional logic test of the entire protection group of the new integrated protection device.

[0079] In one optional implementation, the establishment of a fully covered simulation debugging platform in step S1, and the simultaneous physical wiring and functional verification, can also be carried out by constructing a three-dimensional visualization debugging environment through augmented reality (AR) technology. Combined with the physical parameter model of the equipment, the immersive simulation verification of the wiring path can be realized, and the protection function triggering scenario can be rehearsed in the virtual environment. The mechanical feedback of the actual wiring operation can be simulated through the tactile feedback device, forming a closed-loop verification system that links the virtual and real worlds.

[0080] In another optional implementation, the establishment of a fully covered simulation debugging platform in step S1, and the simultaneous physical wiring and functional verification can also be carried out through blockchain technology to build a distributed verification network. Smart contracts are used to perform multi-node parallel verification of communication protocol compatibility and protection logic execution results. The entire lifecycle of the debugging process can be traced through tamper-proof on-chain records. In addition, a real-time data synchronization link is formed by combining edge computing nodes and physical operation terminals to ensure the timing consistency between simulation verification and actual operation.

[0081] In this embodiment of the application, step S1, which establishes a comprehensive simulation debugging platform and simultaneously conducts physical wiring and functional verification, also includes:

[0082] like Figure 1 As shown, the preparatory work for the wiring layout and equipment commissioning of the S1 site modification project includes:

[0083] The preparation work for S1-1 wiring includes:

[0084] like Figure 2 As shown, safety measures are performed on the customized terminal block 109, including disconnecting the intermediate connecting piece of the relevant terminals of the output circuit and the operating circuit, and inserting a red warning insulating spacer; note that the customized terminal block 110 is not connected to the switch cabinet terminal block and does not require safety measures.

[0085] The commissioning and wiring procedures for integrated protection equipment and customized terminal blocks include:

[0086] The prefabricated aviation plug cables of the transitional integrated protection equipment are connected to the customized terminal block 109 according to the drawings;

[0087] Specifically, the transitional integrated protection equipment serves as a backup input for the "circuit potential confirmed signal" via a circuit breaker connected to the positive power supply. The circuit breaker is initially in the open state and will only be closed after the equipotential monitoring of the outgoing circuit operation circuit is confirmed to be normal. This signal is used for the installation of the online detection module in the transitional integrated protection equipment.

[0088] The prefabricated aviation connector cables of the new integrated protection equipment are connected to the customized terminal block 110 according to the drawings;

[0089] The new integrated protection equipment is connected to the positive power supply via a circuit breaker as a backup input for the "circuit potential confirmed signal". The circuit breaker is initially in the open state and will be closed only after the equipotential monitoring of the outgoing circuit operation circuit is confirmed to be normal. This signal is used for the installation of the online detection module on the new integrated protection equipment.

[0090] The wiring for customized terminal blocks and analog circuit breakers includes:

[0091] The tripping and closing operation circuit of the transition protection equipment is connected to the simulated circuit breaker equipment 104 via the customized terminal block 109. The device sends a virtual tripping and closing command to simulate the circuit breaker to open and close normally.

[0092] The tripping and closing operation circuit of the new integrated protection equipment is connected to the simulated circuit breaker equipment 104 via a customized terminal block 110. The device sends a virtual tripping and closing command to simulate the circuit breaker to open and close normally.

[0093] The wiring for customized terminal blocks and relay protection testers includes:

[0094] The three-phase protection voltage terminals of the customized terminal block 109 are connected to the first group of voltage U of the relay protection tester. a / U b / U c The three-phase protection current terminals of the customized terminal block 109 are connected to the first group of current I of the relay protection tester. a / I b / I c ;

[0095] The three-phase current measurement terminals of the customized terminal block 109 are connected to the second group of current I of the relay protection tester. x / I y / I z / ;

[0096] To ensure that the analog excitation of the transitional integrated protection equipment and the new integrated protection equipment is the same during the commissioning phase, the three-phase protection voltage terminals of customized terminal block 110 and customized terminal block 109 are connected in parallel, the three-phase protection current terminals of customized terminal block 110 and customized terminal block 109 are connected in series, and the three-phase measurement current terminals of customized terminal block 110 and customized terminal block 109 are connected in series.

[0097] like Figure 1 As shown, the communication function test of the S1-2 integrated protection equipment is performed.

[0098] All integrated protection devices are connected to the auxiliary monitoring system via a network of switches. The auxiliary monitoring system uses the same communication protocol as the on-site back-end monitoring system to communicate with the integrated protection devices. If the integrated protection devices and the auxiliary monitoring system are debugged normally, it means that they can also be connected to the on-site back-end monitoring system normally. All communication function tests are completed before on-site construction.

[0099] First, export a backup of the database configuration of the on-site backend monitoring system;

[0100] Import the database configuration backup of the on-site backend monitoring system into the auxiliary monitoring system;

[0103] The transitional integrated protection equipment is connected to the auxiliary monitoring system, including template import, creation of monitoring screens, and completion of communication points for incoming remote signaling, outgoing remote control, and analog telemetry.

[0104] S1-3 Integrated Protection Equipment Group Protection Function Test:

[0105] The auxiliary monitoring system provides the transitional integrated protection equipment with on-site operation settings and soft pressure plates;

[0106] The tester applies external excitation to the transition protection device to simulate the fault condition of the primary equipment. After the transition protection device operates, it sends trip and close commands to the simulated circuit breaker device to complete the functional logic test of the entire protection group of the transition protection device.

[0107] The auxiliary monitoring system installs setpoints and soft pressure plates for on-site operation on the new integrated protection equipment;

[0108] The tester applies external excitation to the new integrated protection device to simulate the fault condition of the primary equipment. After the new integrated protection device operates, it sends trip and close commands to the simulated circuit breaker device to complete the functional logic test of the entire protection group of the new integrated protection device.

[0109] All protection function tests were completed before on-site construction.

[0110] Among them, such as Figure 2 As shown, the following components are included: relay protection tester 101, transition integrated protection device 102, prefabricated aviation plug cable 103, simulated circuit breaker 104, new integrated protection device 105, prefabricated aviation plug cable 106, switch 107, auxiliary monitoring system 108, customized terminal block 109, customized terminal block 110, snap-fit ​​terminal cable 111, and needle-nose pliers type CT cable 112.

[0111] The relay protection tester 101 can simultaneously provide 6 sets of voltage channels and 6 sets of current channels to simulate the excitation output under normal and fault conditions of a substation. It can also collect passive contact data to verify the continuity of relay contacts and verify the correctness of the behavior of the integrated protection equipment under various simulated conditions, thus avoiding any impact on the substation's operating equipment.

[0112] The transitional integrated protection device 102 is a device that replaces the old integrated protection device and provides all functions during the construction phase when the old integrated protection device is phased out and the new integrated protection device is put into use. The back terminal of the transitional integrated protection device is a prefabricated aviation socket. In this example, the transitional integrated protection device and the new integrated protection device 105 are devices with the same function.

[0113] The prefabricated aviation connector cable 103 and the back terminal of the transition integrated protection equipment are prefabricated aviation socket adapters, which can be used immediately and significantly reduce on-site wiring operations. The prefabricated aviation connector cable 106 and the prefabricated aviation connector cable 103 are interchangeable.

[0114] The simulated circuit breaker 104 can simulate the tripping and closing of a high-voltage circuit breaker and realistically simulate the tripping and closing time of the circuit breaker. It is equipped with multiple sets of relay switching contacts and works with integrated protection equipment to complete the overall test of protection logic performance. The operation circuit of the equipment can be verified without a power outage.

[0115] Switch 107 serves as a transitional integrated protection device, a networking medium for connecting new and old integrated protection devices to the auxiliary monitoring system.

[0116] The auxiliary monitoring system 108 is a background monitoring system installed on a portable computer. It can realize the communication and interaction function between the on-site background monitoring system and the integrated protection equipment, and can add monitoring display screens as needed.

[0117] The customized terminal block 109 corresponds one-to-one with the terminal block distribution of the switch cabinet, enabling the transitional integrated equipment to complete the wiring work in advance according to the switch cabinet drawings even when it is not on-site for modification.

[0118] Customized terminal block 110 and customized terminal block 109 are arranged in the same way and are used for wiring the new integrated protection equipment to ensure that the new integrated protection equipment, after commissioning and confirmation, is just as reliable as the transitional integrated protection equipment.

[0119] The snap-on terminal cable 111 is a quick-connect module 1 that does not require disassembly, used to enable the rapid installation and removal of parallel circuits.

[0120] The needle-nose pliers type CT cable 112 is a quick-connect module 2 that does not require disassembly, used to enable the rapid installation and removal of non-parallel circuits (current circuits).

[0121] In this embodiment of the application, step S2 involves constructing an intelligent analysis platform based on equipment characteristic parameters to perform autonomous adaptation and anomaly detection for device monitoring. This is achieved through pre-inspection of the integrated protection equipment installation before the implementation of the modification construction. However, it is necessary to create an online detection logical view of the equipment installation in the auxiliary monitoring system, including:

[0122] Creating an online monitoring view for the transition protection device installation includes: checking whether the input signals of the transition protection device and the old protection device are consistent. If the same signal is 1 or 0, they are considered consistent. Checking whether the analog signals of the transition protection device and the old protection device are consistent. The amplitude difference of the voltage analog signal is less than 5% and the angle difference is less than 20° compared with the amplitude error of the old protection device. The amplitude difference of the current analog signal is less than 10% and the angle difference is less than 20° compared with the amplitude error of the old protection device. If all of the above are consistent and a "loop potential confirmed signal" is received from the transition protection device, the transition protection installation is considered complete.

[0123] The logic for creating a new integrated protection device installation online detection view includes: checking whether the input signals of the new integrated protection device and the transition integrated protection device are consistent; if the same signal is 1 or 0, they are considered consistent; checking whether the analog signals of the new integrated protection device and the transition integrated protection device are consistent; if the amplitude difference of the voltage analog signal is less than 5% and the angle difference is less than 20° compared with the amplitude error of the transition integrated protection device, and the amplitude difference of the current analog signal is less than 10% and the angle difference is less than 20° compared with the amplitude error of the transition integrated protection device, and all of the above are consistent and a "loop potential confirmed signal" is received from the new integrated protection device, the new protection installation is considered complete.

[0124] Before on-site modification work begins, the installation logic is pre-verified by applying external stimuli. On-site modification can only proceed if the pre-verification passes.

[0125] Pre-installation inspection of transitional integrated protection equipment:

[0126] The tester applies external excitation to the transition protection device to simulate the normal operating conditions of the primary equipment. It closes the circuit breaker of the transition protection device's "circuit potential confirmed signal" and checks whether the transition protection device has met the installation completion conditions through the online detection logic view of the transition protection device installation in the auxiliary monitoring system. If it does not meet the conditions, it checks and adjusts them one by one until it is confirmed that the conditions are met.

[0127] Pre-installation inspection of transitional integrated protection equipment:

[0128] The tester applies external excitation to the new integrated protection equipment to simulate the normal operating conditions of the primary equipment. It closes the circuit breaker of the new integrated protection equipment's "loop potential confirmed signal" and the circuit breaker of the transition integrated protection equipment's "loop potential confirmed signal". The online detection logic view of the new integrated protection equipment installation in the auxiliary monitoring system is used to check whether the new integrated protection equipment has met the installation completion conditions. If it does not meet the conditions, it is checked and adjusted condition by condition until it is confirmed that it meets the conditions.

[0129] Retain the wiring of the transitional integrated protection equipment's aviation plug cable and customized terminal block, disconnect the wiring of the simulated circuit breaker equipment, disconnect the wiring of the new integrated protection device and customized terminal block, and the on-site installation preparation is complete.

[0130] In an optional implementation, the intelligent judgment platform built based on the device feature parameters in step S2, and the autonomous adaptation and anomaly detection of device monitoring can also be achieved through a time-series data-driven deep learning model. An adaptive analysis framework is built by utilizing the time-series correlation between historical operating data and real-time feature parameters. The dynamic evolution of the device installation status is captured by a Long Short-Term Memory (LSTM) network, and the weights of multi-source heterogeneous parameters are assigned by combining an attention mechanism to generate a dynamic threshold adjustment strategy for anomaly detection.

[0131] In another optional implementation, the intelligent judgment platform built based on device feature parameters in step S2, which performs autonomous adaptation and anomaly detection for device monitoring, can also build a distributed diagnostic model through a federated learning framework. Under the premise of ensuring data privacy, the device feature parameters of multiple sites are aggregated for joint training to generate an anomaly detection rule base with generalization ability. The detection protocol can be updated with low latency through lightweight deployment of edge models, forming a cross-site collaborative diagnostic capability.

[0132] In this embodiment of the application, step S2, which involves constructing an intelligent analysis platform based on device characteristic parameters to perform autonomous adaptation and anomaly detection for device monitoring, further includes:

[0133] like Figure 1 As shown, S2 creates a logical view for online device installation monitoring:

[0134] The data used in the views created by the auxiliary monitoring system all come from the input signals and analog signals sent by the integrated protection equipment;

[0135] S2-1 Creates an online monitoring view for the installation of transitional integrated protection equipment. Figure 3 Install an online detection logic view for the transitional integrated protection equipment;

[0136] In this example, the transitional integrated protection device input signal n and the old integrated protection device input signal n represent the same-name inputs involved in the external characteristics of the integrated protection device. The logic view detects whether the input signals of the transitional integrated protection device and the old integrated protection device are consistent. If the same-name signals are both 1 or both 0, they are considered consistent. If any input signal is inconsistent, it is considered that the installation of the transitional integrated protection device is not complete and needs to be checked and adjusted to make them consistent.

[0137] In this example, U ga U represents the A-phase protection voltage of the transition protection device. oa I represents the A-phase protection voltage of the old integrated protection equipment. ga I represents the A-phase protection current of the transition protection device. oaThis indicates the A-phase protection current of the old integrated protection device. Other channels are named similarly. The logic view checks whether the corresponding analog signals of the transition integrated protection device and the old integrated protection device are consistent. If the difference in voltage analog signal amplitude is less than 5% and the angle difference is less than 10° compared to the amplitude error of the old integrated protection device, the voltage channel is considered consistent. If the difference in current analog signal amplitude is less than 10% and the angle difference is less than 20° compared to the amplitude error of the old integrated protection device, the current channel is considered consistent. If any analog signal is inconsistent, the installation of the transition integrated protection device is considered incomplete, and it needs to be checked and adjusted to make it consistent.

[0140] The new integrated protection device input signal n and the transition integrated protection device input signal n represent the same-name inputs involved in the external characteristics of the integrated protection device. The logic view detects whether the input signals of the new integrated protection device and the transition integrated protection device are consistent. If the same-name signals are both 1 or both are both 0, they are considered consistent. If any input signal is inconsistent, it is considered that the installation of the new integrated protection device is not complete and needs to be checked and adjusted to make them consistent.

[0141] In this example, U na U represents the A-phase protection voltage of the new integrated protection device. ga I represents the A-phase protection voltage of the transition protection device. na I represents the A-phase protection current of the new integrated protection device. ga This indicates the A-phase protection current of the transitional integrated protection device. Other channels are named similarly. The logic view checks whether the corresponding analog signals of the new integrated protection device and the transitional integrated protection device are consistent. If the difference in voltage analog signal amplitude is less than 5% and the angle difference is less than 10° compared to the amplitude error of the transitional integrated protection device, the voltage channel is considered consistent. If the difference in current analog signal amplitude is less than 10% and the angle difference is less than 20° compared to the amplitude error of the transitional integrated protection device, the current channel is considered consistent.

[0142] The transition protection installation is considered complete only when the logic view simultaneously detects the "loop potential confirmed signal" of both the new integrated protection device and the transition integrated protection device.

[0143] Online detection of equipment installation completion via logical view can reduce the workload of on-site manual verification.

[0144] The installation of the S2-3 pre-inspection integrated protection equipment has been completed;

[0145] After the wiring layout and equipment debugging work of the S1 site modification construction is completed, the installation is pre-verified by applying external excitation before the on-site modification construction. Only after the pre-verification is passed can the on-site modification be carried out.

[0146] External excitation is applied to the transition protection device using a relay protection tester to simulate the normal operating conditions of the primary equipment. The circuit breaker of the transition protection device with the "circuit potential confirmed signal" is closed. The transition protection device installation online detection logic view of the auxiliary monitoring system is used to check whether the transition protection device has met the installation completion conditions. If it does not meet the conditions, the conditions are checked and adjusted one by one until it is confirmed that the conditions are met.

[0147] External excitation is applied to the new integrated protection equipment using a relay protection tester to simulate the normal operating conditions of the primary equipment. The circuit breaker for the "loop potential confirmed signal" of the new integrated protection equipment is closed, and the circuit breaker for the "loop potential confirmed signal" of the transition integrated protection equipment is also closed. The online detection logic view of the new integrated protection equipment installation in the auxiliary monitoring system is used to check whether the new integrated protection equipment has met the installation completion conditions. If it does not meet the conditions, the conditions are checked and adjusted one by one until it is confirmed that the conditions are met.

[0148] Retain the wiring of the transitional integrated protection equipment's aviation plug cable and customized terminal block, disconnect the wiring of the simulated circuit breaker equipment, disconnect the wiring of the new integrated protection device and customized terminal block, and the on-site installation preparation is complete.

[0149] In this embodiment, step S3 uses a first-level access mechanism to create and run an environment for the transition and dynamic management of the old and new equipment. This allows for rapid access to the transitional integrated protection equipment without disassembly, and the old integrated protection equipment is removed after online testing and installation are completed.

[0150] Connect to transitional integrated protection equipment:

[0152] The non-parallel secondary circuits can be connected to the switch cabinet terminal block through a quick-connect module without disassembly, including all current circuits;

[0153] Transitional integrated protection equipment is powered on and in operation;

[0154] After the voltage detection of the outgoing circuit and the parallel terminal of the operation circuit of the customized terminal block is normal, the safety measures of the customized terminal block are lifted, the red insulating spacer is pulled out, and the middle connecting piece of the relevant terminal of the operation circuit is reconnected.

[0155] Online monitoring and transitional protection equipment installation completed:

[0156] After removing the customized terminal block safety measures, close the circuit breaker of the transition integrated protection device as a backup input for the "circuit potential confirmed signal";

[0157] Confirm successful installation of the transitional integrated protection equipment by using the online detection logic view of the transitional integrated protection equipment installation. If unsuccessful, check and adjust each condition until successful installation is confirmed.

[0158] Dismantle old integrated protection equipment:

[0159] After confirming that the transition protection is installed successfully, remove the outlet pressure plate on the switchgear;

[0163] In an optional implementation, step S3 uses a first-level access mechanism to create and run an environment for the transition and dynamic management of new and old equipment. This can also be achieved by embedding the physical layer using high-frequency carrier communication technology, using the inherent power line channel to transmit control signals and operating parameters of the transition equipment, while constructing redundant control loops and data synchronization channels. A dynamic topology switching algorithm is generated by aggregating and processing data from equipment status sensors, and combined with line load balancing strategies, real-time power allocation and phase compensation control are achieved during the commissioning and decommissioning of new and old equipment.

[0164] In another optional implementation, the environment created and run using a first-level access mechanism in step S3, and the transition and dynamic management of the old and new equipment, can also be achieved through virtual takeover technology based on digital twin mapping. By constructing a holographic digital twin of the operating system and the transition equipment through high-precision modeling, the ownership switching logic is pre-rehearsed in the virtual space and an operation instruction set is generated. Then, the instructions are sent to the physical equipment for execution in stages through a low-latency industrial bus. Combined with the predictive maintenance model to analyze the remaining life characteristics of the old equipment, the switching sequence and redundant resource allocation strategy during the transition period are dynamically adjusted.
