Description

Technical Field

[0001] This invention relates to a method for implementing self-healing control technology in power distribution networks, specifically a method for achieving rapid self-healing by upgrading existing power distribution terminals based on 5G communication. Background Technology

[0002] Since the implementation of distribution network automation, the coverage of remote sensing, remote control, and remote telemetry functions ("three remotes") of distribution network lines in my country has reached 76%. These functions enable the collection of real-time control data for distribution network dispatching, realizing the "three remotes" functions of the main station. Distribution network automation has essentially achieved coverage of distribution main stations to every prefecture-level city and distribution terminals to every medium-voltage line, eliminating the historical "blind dispatching."

[0003] Distribution automation planning needs to shift towards improving the practicality of distribution automation, and increasing effective terminal coverage requires a shift from "breadth" to "depth." Further efforts are needed to enhance the practicality of distribution automation in terms of improving grid reliability, reducing the intensity of manual maintenance, and increasing efficiency while reducing manpower, ultimately achieving the goal of self-healing control of the regional distribution network.

[0004] For metropolitan areas that are constrained by urban planning and cannot build new fiber optic networks, the main goal of technical personnel is to develop technologies that enable rapid self-healing of power supply areas, are replicable and scalable, and suitable for future promotion and application. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method for rapidly self-healing existing power distribution terminals based on 5G communication to achieve rapid self-healing of the power supply area.

[0006] One technical solution to achieve the above objective is: a method for rapidly self-healing existing power distribution terminals based on 5G communication, comprising the following steps: Step 1: Without replacing the existing remote control distribution terminals, set up a separate logic master control to collect the remote control information of the distribution terminals. Step 2: Point-to-point communication is performed between the above-mentioned logic master control and power distribution terminal to transmit remote information using the Goose protocol. After conversion, the R-goose protocol is transmitted using the 5G wireless channel. Step 3: The logic master control uses 5G embedded synchronization technology to synchronize, logically compare, and analyze the collected information to obtain the fault location result. Step 4: The above-mentioned logic master control then sends a fault trip command via the 5G wireless channel using the Goose protocol. After conversion, the command is transmitted via the 5G channel to the power distribution terminal using R-goose. Step 5: The power distribution terminal executes the circuit breaker tripping command; Step 6: After the fault is isolated, the logic master control sends a closing command back to the power distribution terminal based on the switch tripping status sent by the power distribution terminal and the backup power switch determined by the advanced application software set by the logic master control. The command is transmitted via 5G wireless channel using the Goose protocol. Step 7: Upon receiving the closing command, the distribution terminal executes the closing command, closes the backup power switch, completes self-healing, and restores power supply to the fault-free section.

[0007] Furthermore, in step 3, the specific operation method of the external synchronization technology is as follows: embedding a Beidou or GPS system from the outside to form a clock source for the self-healing synchronization of the power distribution network. Each acquisition unit timestamps the data before sending it out. When the receiving unit receives the data containing the timestamp, it synchronizes the data based on the timestamp during data comparison and logical judgment.

[0008] Furthermore, after completing all steps, the overall self-healing time is controlled within 200ms-300ms.

[0009] The present invention discloses a method for rapidly self-healing existing power distribution terminals based on 5G communication. By utilizing the 5G wireless channel, the existing power distribution terminals can be upgraded to achieve rapid self-healing of the power distribution network. Attached Figure Description

[0010] Figure 1 This is a system architecture diagram of a method for rapidly self-healing existing power distribution terminals based on 5G communication, according to the present invention. Detailed Implementation

[0011] To better understand the technical solution of the present invention, detailed descriptions are provided below through specific embodiments: Please see Figure 1 This invention discloses a method for rapidly self-healing existing power distribution terminals based on 5G communication. The aim is to develop a self-healing control system applicable to power distribution automation areas that have already implemented remote signaling, remote measurement, and remote control (hereinafter referred to as "three remotes"). The method specifically includes the following steps: Step 1: Without replacing the existing three-remote power distribution terminal 2, set up a separate logic master control 1 to collect the three-remote information of the power distribution terminal.

[0012] Step 2: Point-to-point communication is performed between the above-mentioned logic master control and power distribution terminal. The three remote information is transmitted in Goose protocol. After conversion, the R-goose (remote transmission Goose) protocol is transmitted using 5G wireless channel.

[0013] Step 3: The overall logic control uses 5G embedded synchronization technology to synchronize, logically compare, and analyze the collected information to obtain fault location results. Currently, 5G does not have synchronization capabilities. By loading the BeiDou / GPS time synchronization system, a 5G-based self-healing control system capable of data synchronization is constructed. An externally embedded BeiDou / GPS system forms the clock source for the power distribution network's self-healing synchronization. Each acquisition unit timestamps its data before sending it. The receiving unit receives the timestamped data and synchronizes it based on the timestamp during data comparison and logical judgment. This technology is referred to as embedded synchronization technology.

[0014] Step 4: The above-mentioned main logic control then sends a fault trip command via the 5G wireless channel using the Goose protocol. After conversion, the command is transmitted via the 5G channel to the power distribution terminal as R-goose (remote Goose).

[0015] Step 5: The power distribution terminal executes the circuit breaker tripping command.

[0016] Step 6: After the fault is isolated, the logic master control sends a closing command back to the distribution terminal based on the switch tripping status sent by the power distribution terminal and the backup power switch determined by the advanced application software set by the logic master control, using the 5G wireless channel to transmit the Goose protocol.

[0017] Step 7: Upon receiving the closing command, the distribution terminal executes the closing command, closes the backup power switch, completes self-healing, and restores power supply to the fault-free section.

[0018] After completing all the above steps, the overall self-healing time is controlled within 200ms-300ms.

[0019] While 5G wireless communication boasts advantages such as low latency, high reliability, massive connectivity, and high security, making it superior to other wireless communication technologies for general business applications, it falls short for real-time self-healing control communication due to unpredictable latency fluctuations. For example, a certain operator's self-tested one-way end-to-end speed typically completes transmission within 10ms, but occasional anomalies occur between 50ms and 90ms. To support innovative services in distribution network self-healing control systems, this invention utilizes edge computing (MEC) technology to push low-latency services to the edge of the access network. This enables local loopback of power data, forming the shortest data transmission path and achieving end-to-end data transmission within 10ms.

[0020] GOOSE is a real-time, high-speed, peer-to-peer data transmission technology with advantages such as short transmission latency and high communication reliability. GOOSE is a peer-to-peer (P2P) communication mode, generally applicable to fiber optic networks. Using the GOOSE protocol in 5G wireless communication can guarantee the reliability of message transmission, and it is simple to configure, easy to implement, and highly versatile, making it of great significance for the application of distributed self-healing control systems in power distribution networks.

[0021] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any variations or modifications to the above embodiments that are within the spirit and essence of the present invention will fall within the scope of the claims of the present invention.
