Anti-misoperation method for transformer station based image recognition

Abstract

The invention discloses an anti-misoperation method for a transformer station based image recognition, and the method is characterized in that an image collection unit obtains static and dynamic image information of transformer station equipment; an image processing unit converts the information into a logic criterion; the logic criterion is combined with electrical quantities which are obtained by all partitioned equipment measurement and control unit in a transformer station monitoring system and are used for reflecting the switching-on and switching-off positions of equipment, thereby forming double-locking criteria; the double-locking criteria jointly serve as the control conditions for sequential control or local control of switching operation, thereby achieving the image linkage of operated equipment (switches or knife switches) on an operating interface. The method is applied to an anti-misoperation method for the transformer station based image recognition, thereby preventing the single electrical logic locking from causing equipment misoperation and improper equipment operation because of a judgment error so as to avoid electrical misoperation, effectively improving the operation safety and reliability and switching operation efficiency of a transformer station, and providing powerful support for the safe and stable operation of a power grid.

Description

technical field [0001] The invention relates to the technical field of electric power operation control, in particular to a method for preventing misoperation of a substation based on image recognition. Background technique [0002] The substation is an important part of the power system, and it is responsible for important tasks such as voltage level conversion, input / removal of load, etc. Due to the large number of equipment such as circuit breakers, isolating switches, and grounding isolating switches in substations, if improperly operated, misoperation accidents are very likely to occur, resulting in large-scale power outages, equipment damage, and even casualties. In order to improve the safety of substation operation, microcomputer anti-misoperation operating system is widely used to prevent substation misoperation accidents. The system is mainly a computer key-operated anti-mistake system. Whether the anti-mistake locking mode is a separate five-proof system or an in...

Problems solved by technology

The reliability of a single electrical quantity as a logical criterion is not high, and it cannot fundamentally solve the electrical misoperation accidents caused by misjudgment of equipment and improper operation of equipment.
