Description

Intelligent generation and misoperation-preventive locking verification method and system for operation ticket Technical Field The invention relates to the technical field of operation and maintenance of power transmission and transformation equipment, in particular to an intelligent generation and misoperation-preventive locking verification method and system for operation tickets. Background In the operation and maintenance process of the power system, an operation ticket is an important basis for guiding an operator to operate equipment, and is mainly used for standardizing the operation sequence of primary equipment such as a breaker, a disconnecting switch, a grounding disconnecting switch and the like, so that the operation safety of a power grid and the standardization of the operation process are ensured. Meanwhile, in order to prevent equipment damage or power grid accidents caused by misoperation, an operation process is usually required to be checked by combining an anti-misoperation locking system so as to avoid dangerous operations such as pulling a disconnecting switch, and connecting a grounding disconnecting switch with electricity. In the prior art, the generation of operation tickets mainly depends on manual experience or an automatic generation mode based on a rule base. The automatic generation method based on rules generally generates corresponding operation steps according to a target operation task through a preset operation template or logic rule, and performs verification through an anti-misoperation locking system after the operation steps are generated. Such methods have increased the level of automation to some extent, but still have the following problems: In the prior art, the generation of the operation path and the error-proof locking check are generally two independent processes, namely, the complete operation sequence is generated first, and then the locking check is carried out. This "pre-generation, post-verification" approach tends to produce a large number of operation sequences that are not executable or require repeated modification, reducing overall system efficiency and increasing the uncertainty in the generation of the operation ticket. Disclosure of Invention In order to overcome the defects in the prior art, the embodiment of the invention provides an intelligent operation ticket generation and misoperation-preventive locking verification method and system, which solve the problems that an operation sequence is generated first and then verified in the prior art, so that an inexecutable operation sequence is easy to generate, the efficiency is low and the uncertainty is high.

In one embodiment, an initial topological graph is built, electrical sections of electrical equipment are divided to obtain a plurality of electrical sections, a section level topological structure is built, the method comprises the steps of identifying conducting connection relations and breaking connection relations among nodes of the electrical equipment based on the initial topological graph to obtain an initial connection relation set, identifying common connection areas and ring networks and double bus structures according to the initial connection relation set, dividing the common connection areas into a first electrical section through traversing searching, dividing the ring networks and the double bus structures into a second electrical section through key cutting point analysis, establishing connection corresponding relations among the electrical sections according to breaking equipment connected with different electrical sections, representing each electrical section as a node and each breaking equipment as a connecting edge, and building the section level topological structure.
