Problems solved by technology

[0003] Existing line fault handling schemes rely on dispatchers to judge and analyze faults, use manual records for reporting, and communicate information through manual telephone calls. The risk of cascading failures between DC systems cannot meet the requirements for timely handling of grid failures in AC-DC hybrid grids

Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0020] Such as figure 1 The power grid fault intelligent disposal system based on the knowledge map shown includes a fault disposal plan analysis module 1, a map generation module 2, a fault perception module 3, a fault risk assessment module 4, and a fault intelligent disposal module 5. The fault disposal plan analysis module Module 1 is used to obtain non-structural information from dispatching procedures, fault handling rules, fault handling plans (preplans refer to the possible fault forms based on the expected power grid, and the handling measures when the fault occurs), and work instructions. The power grid fault disposal text (grid fault disposal text is unstructured text, which cannot be directly stored in the database and used directly, and the corresponding fault disposal entity is not a standard device name, so it is necessary to extr...

Abstract

The invention discloses a power grid fault intelligent processing system based on a knowledge graph. A fault processing plan analysis module of the system is used for obtaining a fault processing entity and relation knowledge; the graph generation module is used for storing the identified entities and entity relationships in a triple form to obtain an equipment entity knowledge graph, an accident plan knowledge graph and a disposal flow knowledge graph; the fault sensing module is used for intelligently sensing and collecting information related to power grid faults in a power grid system; the fault risk assessment module is used for carrying out risk identification; and the fault intelligent processing module is used for reasoning a processing measure suitable for the current fault based on the accident plan knowledge graph and the processing flow knowledge graph in combination with the topological change, the power flow and the alternating current power supply frequency before and after the power grid fault after the power grid has the line fault. According to the invention, comprehensive intelligent alarm information can be sensed in all directions, and scheduling personnel are guided to carry out intelligent disposal on power grid risks and power supply restoration based on the established knowledge graph.

Description

technical field [0001] The present invention relates to the cross-technical field of artificial intelligence and power grid regulation, and specifically refers to a system and method for intelligent handling of power grid faults based on knowledge graphs. Background technique [0002] With the formation of my country's AC-DC hybrid large power grid, the structure of the power grid is becoming more and more complex, and the operation mode is flexible and changeable, which leads to the increasingly complex regulation business. If a single power grid failure is not dealt with in time, it will cause a chain failure reaction between the AC and DC systems, which will affect the safety of the power grid. Stability poses a serious threat. Power grid fault handling mainly consists of dispatchers receiving fault handling signals, analyzing power grid operation status, evaluating power grid security risks, handling line faults, and recording fault handling information based on fault tex...
