Method for judging safe area of T-shaped electric power circuit work ticket based on regular way

Abstract

The invention discloses a method for judging a safe area of a T-shaped electric power circuit work ticket based on a regular way. The method comprises the following three steps of: (1) based on a graphical billing system, building a network topology relation chart of a T-shaped electric power circuit, encoding a grounded switch and a fault point in a real-number-coding way; (2) on the basis of acquiring the minimum closed interval of the grounded switch which contains a fault maintaining point on the main circuit, and automatically identifying whether the closed interval contains a branch circuit or not according to codes of two end points of the closed interval; (3) establishing a judging rule of the safe area of the fault maintaining point on the main circuit; and (4) based on an encoding rule, building a method for projecting from the branch circuit to the main circuit, projecting the fault maintaining point of the branch circuit to the main circuit, and obtaining a judging conclusion applied to the safe area of the fault maintaining point of the main circuit after projection. By the method, the billing efficiency of the work ticket can be improved; the requirement of quick, convenient and accurate management on the work ticket is met; and the problem of construction safety and grid reliability is solved.

Description

technical field [0001] The invention relates to a rule-based method for judging the safe area of ​​a T-shaped power line work ticket. Background technique [0002] The line work ticket is the premise to ensure safe production. Whether it is qualified or not is directly related to the personal safety of the construction team and the stable and reliable operation of the system, which is of great significance to safe production. The line work ticket refers to the written basis for specifying the staff, explaining the work tasks and work content, implementing safety technical measures, performing work permits, work guardianship, work interruption, transfer and termination when working on the power line that has been put into operation. It is divided into the first type of work ticket and the second type of work ticket. When the power line is overhauled or constructed, in order to ensure safety, the first type of work ticket for the power line must be processed first, and then ...

AI Technical Summary

Problems solved by technology

Many software suppliers have also developed visual and graphical work ticket billing systems. In the core technology of work ticket security area determination, methods such as graph theory-based adjacency matrix method, tree search method, and connection matrix remainder method are mainly used. These methods The obvious disadvantages are large amount of calculation, single function, waste of storage space
