Substation anti-misoperation logic intelligent generating method based on topology analysis

Abstract

The invention discloses a substation anti-misoperation logic intelligent generating method based on topology analysis, and aims at avoiding configuring locking logic for preventing misoperation and self-adapting, reducing building and maintenance workloads, and reducing use complexity, based on ensuring the reliability and the rigor of a Five Prevention system. The substation anti-misoperation logic intelligent generating method based on topology analysis comprises the following steps: analyzing and exporting primary equipment of the substation and connection relation thereof included in an SSD file, mapping the primary equipment of whole substation and connection relations thereof into an undirected graph according to the topological relation, analyzing and summarizing the operation rules of various kinds of primary equipment and abstracting to be a language which can be used by a computer, combining the undirected graph with the language which can be used by the computer to generate equipment locking logic by using nomography from the aspect of mathematics, and thus achieving the purpose of preventing misoperation. According to the substation anti-misoperation logic intelligent generating method based on topology analysis, innovation is provided for the inference engine of the traditional Five Prevention system from the aspect of implementation model, the technological level of intelligent substation for preventing misoperation is improved, and the construction and maintenance efficiencies are greatly improved.

Description

technical field [0001] The invention relates to an anti-misoperation logic generation method based on 61850 intelligent substation topology analysis, which is used in the technical field of substation prevention of electrical misoperation. Background technique [0002] Among the many unsafe factors in electric power production, human error or negligence is the most complicated and difficult to control important factor. Therefore, the substation misoperation accident has the characteristics of complex causes, high chance and randomness, and great difficulty in prevention and control. [0003] The "five defenses" of the power system refer to: ① prevent wrong opening and closing of the circuit breaker; ② prevent the disconnection and closing of the disconnector with load; ⑤ To prevent mistaken entry into the charged compartment, the anti-misoperation locking system has been developed for many years and has been widely used at present. It is an important technical measure aimed...

Problems solved by technology

[0004] The current microcomputer error prevention in substations requires the maintenance personnel to directly define the operation locking relationship between devices. Each device must manually write the error prevention logic. Poor, when the equipment is changed or the substation is expanded, the affected locking logic needs to be rewritten, and the maintenance workload is heavy
