Description

Technical Field

[0001] This invention relates to the field of power system technology, and in particular to a method and system for reading power system main wiring diagrams based on Konva. Background Technology

[0002] In the power system field, the main wiring diagram of a substation refers to a circuit that receives and distributes electrical energy, consisting of various switching devices, power transformers, circuit breakers, disconnectors, surge arresters, instrument transformers, busbars, power cables, phase-shifting capacitors, and other electrical equipment connected in a specific order. Figure 1 It is usually represented in the form of a single-line diagram, which intuitively shows the network topology and equipment distribution information of the entire substation.

[0003] In the power information protection system, the main wiring diagram is widely used. Through the main wiring diagram of the substation in the information protection system, on-site engineers can view the overall structure and operating status of the substation equipment (generally connection and disconnection) from all angles. This allows engineers to understand the real-time information of the equipment in a timely manner, locate faulty equipment in a short time, and eliminate the faults in a timely manner, thereby avoiding the occurrence of more faults and improving operation and maintenance efficiency.

[0004] Currently, the existing technology for viewing main wiring diagrams in power systems involves reading locally stored files using graphical configuration client tools, and does not support reading remote main wiring diagram files. This means that the same substation main wiring diagram may be stored at different substations, and different substation systems can only view the local main wiring diagram, requiring the graphical configuration client tool to be installed locally.

[0005] The structure and information of substation equipment are subject to change, such as equipment renovation, replacement, and changes in related information. These changes inevitably require the main wiring diagram to be updated synchronously. Due to technical limitations, the main wiring diagram itself cannot be shared and read, which means that all station-end systems must resynchronize the main wiring diagram, and this synchronization is done manually, which increases the workload of operation and maintenance to some extent. Summary of the Invention

[0006] In view of this, the purpose of this invention is to provide a method and system for reading the main wiring diagram of a power system based on Konva, which can realize the sharing of main wiring diagram reading and improve operation and maintenance efficiency.
