Description

Technical Field

[0001] This invention relates to the field of power system substation monitoring and intelligent fault handling technology, and in particular to a fault handling strategy generation and collaborative handling method and system for substation monitoring. Background Technology

[0002] With the continuous expansion of the power grid and the increasing number of substations, centralized substation monitoring has become the main form of power grid operation and management. In centralized monitoring scenarios, monitors need to simultaneously monitor the operating status of a large number of substations. When a fault event occurs, they need to complete a series of complex operations such as fault analysis, generation of handling strategies, and multi-system collaborative handling in a short period of time.

[0003] The existing substation monitoring fault handling mode has the following main problems: First, the handling strategies rely on human experience. The existing system lacks a systematic accumulation and automatic recall mechanism for fault handling knowledge. Monitors need to formulate handling plans based on their personal experience. The quality of handling varies among different personnel, and omissions or misjudgments are prone to occur in complex fault scenarios.

[0004] Secondly, the handling process lacks structured support. After a fault occurs, the monitoring personnel need to manually switch between multiple systems to query information such as alarm data, fault waveforms, real-time measurement data, historical defects, intelligent inspection results, and wiring diagrams. The operation is scattered and inefficient, making it difficult to meet the timeliness requirements for rapid fault handling.

[0005] Third, there is insufficient cross-system collaborative handling capability. Substation fault handling often involves multiple business systems, such as the substation centralized control system, defect management system, intelligent inspection system, fault recording system, and work order system. Existing technologies lack a unified collaborative handling mechanism, and the information linkage between various systems is insufficient, which cannot effectively support the coordinated response during the fault handling process. Summary of the Invention

[0006] The purpose of this invention is to provide a method and system for generating and collaboratively handling fault handling strategies for substation monitoring. This method automatically generates fault handling strategies based on fault event information and transforms them into executable, interconnected, and feedback-enabled handling step cards, thereby improving the efficiency, standardization, and collaborative handling capabilities of substation monitoring fault handling. This invention is achieved through the following technical solutions.

[0012] Optionally, the standardized fault description includes device type, fault type, fault level, and associated alarm signal.

[0013] Optionally, the construction of the expert knowledge base includes: extracting core knowledge elements from at least one knowledge source, such as substation anomaly handling plan, on-site operation procedures, and historical fault cases; wherein, the core knowledge elements include equipment type, fault type, handling action, signal interpretation, verification points, and consequence analysis; The core knowledge elements are standardized and normalized to establish the relationships between them and form a structured knowledge network. It supports operations and maintenance personnel to supplement new knowledge through human-computer interaction. After semantic conflict verification and review, the knowledge is updated to the structured knowledge association network, thereby completing the construction of the expert knowledge base.

[0014] Optionally, based on the standardized fault description, a matching search is performed in the handling expert knowledge base to obtain the basic handling process framework corresponding to the fault event information, including: matching the corresponding standard handling process based on the equipment type, fault type, fault level, and associated alarm signal of the standardized fault description; For complex faults caused by multiple overlapping factors, cross-device collaborative handling steps are supplemented by association rule reasoning. Based on the standard handling process and the cross-device collaborative handling steps, the basic handling process framework is generated.

This can improve the efficiency of automated processing while retaining the necessary manual confirmation process, thereby enhancing the efficiency of fault handling collaboration and execution security.
