Abstract
Description
Technical Field
[0001] The present invention relates to the field of power distribution Internet of Things technology, and in particular to a method, system, device and storage medium for electrically driving and lighting a power distribution network. Background Art
[0002] As the construction of new power systems advances, a vast data collection network is formed through massive IoT nodes. Millions of medium and low voltage smart distribution devices and various sensors are continuously connected. The digitalization and transparency of distribution networks have made significant progress: first, the digitization of state quantities is achieved based on the digitization of electrical quantities; second, coverage of the medium-voltage distribution network is extended to the low-voltage distribution network. Through IoT sensing technology, building on the existing IoT smart substations and driven by electricity, automated IoT sensing modeling of medium and low voltage distribution networks is achieved. By illuminating a single network, we are laying the foundation for the digitalization and transparency of distribution networks.
[0003] When the existing distribution network equipment is put into operation and the power grid is lit up, it generally needs to go through two business processes: distribution network modeling and distribution network transmission. That is, on the PMS side, the GIS map is manually drawn according to the planning and design drawings to generate the topology synchronously. The PMS generates a single-line diagram based on the GIS. After manual adjustment, it is published as the source data of the model to the distribution, supply and service application systems; on the distribution master station side: because the PMS single-line diagram cannot directly meet the scheduling application requirements, the distribution master station is generally required to regenerate the scheduling operation single-line diagram and configure the three remote information - publish to the debugging state (red map) - manually transmit the point - publish the operation state to black Figure 4 The graphical modeling and equipment transmission processes are lengthy, complex, inefficient, and costly. Furthermore, distribution networks are numerous and widespread, with flexible and ever-changing medium-voltage distribution network line changes and equipment changes, and complex and large-scale low-voltage distribution network lines. Existing grid topology modeling relies on manually drawn graphics, manually configured point tables, and fixed parameters, which is labor-intensive, tedious, and prone to errors.

[0096] Reference Figure 2 The embodiment of the present invention provides a method for lighting a distribution network by electric drive, which is executed by a distribution master station and includes but is not limited to the following steps:
[0097] S100 receives the device identity self-description information sent by the distribution terminal;
[0098] S200. Automatic device identification, device registration, and device access authorization based on device identity self-description information;
[0099] S300 receives the capability description information sent by the distribution terminal;
[0100] S400 parsing capability description information, and generate three remote configuration point table;
[0101] S500 receives a first message sent by the power distribution terminal, the first message including a power event, a power supply event, a current mutation value caused by power supply, and a self-describing file;
[0102] S600. Based on the first information, carry out distribution network topology identification and form a connection relationship between medium and low voltage distribution network equipment;
[0103] S700. Generate a geographical layout based on geographic information and low voltage distribution network equipment connection relationship;
[0104] S800 uses an AI-based automatic layout algorithm to generate electrical wiring diagrams based on the connection relationships of medium and low voltage distribution network equipment;
[0105] S900 according to the feeder automation mode, sends protection setting parameters and target distribution line topology information to the distribution terminal;
[0106] S1000 receives the transmission result sent by the distribution terminal;
[0107] S1100. Switch the target distribution line to the operating state, and send a first instruction to the distribution terminal, where the first instruction is an instruction to switch from the test state to the operating state.
[0108] Specifically, in this embodiment, before executing step S100, that is, before receiving the device identity self-description information sent by the power distribution terminal, the following steps need to be executed:
[0109] S000. The distribution switch equipment set is energized.
[0110] Specifically, step S000, that is, the step of energizing the power distribution switch assembly, includes:
[0111] S001. After installing the intelligent switch assembly in the distribution network, adjust the intelligent switch assembly to the test state;
[0112] S002. Close the feeder outlet circuit breaker and supply power;
[0113] S003. Install a complete set of intelligent switches in the downstream distribution network to obtain power;
[0114] S004. Close the circuit breaker step by step according to the preset time limit to supply power.
[0115] In this embodiment, after the intelligent switch assembly is installed in the distribution network, it is in a "testing state" with the intelligent switches in the open position. When the substation feeder outlet circuit breaker closes and energizes, the downstream intelligent switch assembly connected to the feeder outlet circuit breaker receives power. The intelligent switch assembly then closes and energizes the circuit breaker in stages according to the set time delay. The distribution terminals detect the energization and energization of the intelligent switches, generate energization and energization events, and report them to the master distribution station.
[0116] In an embodiment of the present invention, the execution subject is the power distribution master station, that is, the power distribution master station receives the device identity self-description information sent by the power distribution terminal, and then realizes the automatic identification, registration and access authorization of the power distribution equipment based on the received device identity self-description information. Specifically, after the power distribution terminal is powered on, it actively sends a connection login message to the power distribution master station. The power distribution master station receives the login message and identifies the connection message, and completes the automatic identification, registration and access authorization of the power distribution equipment. Then, the capability description information sent by the power distribution terminal is received, and the power distribution master station parses the capability description information and automatically generates a three-remote configuration point table; the device identity self-description information sent by the power distribution terminal is collected to automatically perform primary and secondary equipment management. The power distribution master station collects and parses information such as power-on events, power-supply events, current changes caused by power supply, and topology description files sent by the power distribution terminal, conducts distribution network topology identification, and automatically forms the connection relationship between medium and low voltage distribution network equipment. Specifically, the distribution master station activates the medium-voltage topology identification service based on collected data from power-in / power-out events and current surges caused by power-out, completes the medium-voltage distribution network topology identification, and automatically forms the connection relationships of the medium-voltage distribution network equipment. Based on the low-voltage topology description file transmitted by the distribution terminal (distribution fusion terminal), the distribution master station activates the low-voltage topology identification service to complete the low-voltage topology identification. Relying on the distribution transformer PMSID or medium- and low-voltage connection descriptions transmitted by the distribution terminal, the distribution network medium- and low-voltage topology splicing is achieved, and the topological connection relationships are stored in a relational database. The distribution master station automatically generates a geographic layout map by integrating geographic location information, pole number descriptions, and other information transmitted by the distribution terminal, along with the identified topological connection relationships. The distribution master station uses an artificial intelligence-based automatic layout algorithm to automatically generate electrical wiring diagrams and substation wiring diagrams based on the connection relationships of the medium- and low-voltage distribution network equipment and auxiliary information. The distribution master station stores the generated geographic layout map, electrical wiring diagrams, and substation wiring diagrams in a relational database. The distribution master station, distribution terminals, and transmission devices work together to automatically transmit the entire process and generate transmission reports based on transmission task orders. Specifically, the distribution master station develops transmission projects and transmission tasks in red map mode. The distribution master station, distribution terminals, and transmission devices work together to automatically issue transmission instructions one by one based on the transmission tasks, analyze and compare the transmission results, and generate transmission reports, achieving fully automated transmission. After completing the transmission, the distribution master station can automatically download topology information and fixed value parameters to the distribution terminal according to the FA mode; or, based on operational needs, the dispatcher can set fixed values and parameters on the distribution master station side and then send the parameters and fixed values to the distribution terminal; finally, the distribution master station switches the target distribution line to "operational state" and simultaneously issues instructions to the distribution terminal to switch from "test state" to "operational state." Specifically, the distribution master station switches the distribution line from "test state" to "operation state" based on the distribution line. The distribution master station sends instructions to the distribution terminal to switch the distribution terminal on the line from "test state" to "operation state".After the distribution terminal switches to the "operating state", when it detects power supply, power transmission, and current mutation and sends it to the distribution master station, the distribution master station ignores the information, does not start topology identification, update topology connections, generate graphics and other services.
[0117] In this embodiment, the power distribution master station has the ability to analyze the power supply / power transmission sequence, automatically identify the topology, describe the aggregate topology, automatically model the self-description information of the equipment, and automatically generate a map; through information interaction with the power distribution terminal, it can realize equipment self-registration and plug-and-play, primary and secondary automatic modeling, automatic topology and mapping, and automatic transmission, so that the equipment can run as soon as it is powered on.

[0127] In this embodiment, the execution entity is the distribution terminal. The distribution terminal first sends self-describing device identity information to the distribution master station to enable automatic identification, registration, and access authorization of the distribution device. The distribution terminal then transmits capability description information according to the IoT model, allowing the distribution master station to analyze this capability description information and automatically generate a three-remote configuration point table. This allows the distribution master station to automatically manage primary and secondary devices by integrating the self-describing device identity information sent by the distribution terminal. The distribution terminal transmits information such as power-on events, power-on events, current changes caused by power-on, and topology description files. The distribution master station then analyzes this information, identifies the distribution network topology, and automatically establishes connections between medium and low voltage distribution network devices. The distribution terminal receives protection setting parameters and target distribution line topology information from the distribution master station. It then automatically performs transmission according to the transmission task list and generates a transmission result. After generating the transmission result, the distribution terminal sends it to the distribution master station. Upon receiving the transmission result, the distribution master station switches the target distribution line to "operational" mode and simultaneously issues corresponding instructions to the distribution terminal. The distribution terminal receives the instruction to switch from the test state to the operation state and is put into operation according to the instruction.

The distribution master station, distribution terminal, and transmission device work together. The distribution master station automatically issues transmission instructions one by one according to the transmission tasks, analyzes and compares the transmission results, and generates a transmission report to achieve automatic transmission of the entire process.
[0150] (7) Automatic downloading of fixed values and topology: After the power distribution master station completes the transmission, it can automatically download the topology information and fixed value parameters to the power distribution terminal according to the FA mode; or according to the operation needs, the dispatcher sets the fixed values and parameters at the power distribution master station and then sends the parameters and fixed values to the distribution terminal;
