Transformer substation intelligent anti-misoperation method based on depth architecture

Abstract

The invention discloses a transformer substation intelligent anti-misoperation method based on a depth architecture. The method is characterized in that through configuring a device description format, configuring the logic symbol relationship, configuring the goose transceiving relationship, configuring a lock scheme and the device corresponding relationship, and the like, the relationship amonga station control layer, a spacing layer, a process layer and three-layer locking logic is enhanced, and the relationship is uniformly displayed and operated on station control layer equipment in a graphical interface mode, so substation workers can conveniently master the three-layer locking logic.

Description

technical field [0001] The invention belongs to the field of electric power automation, in particular to an intelligent anti-misoperation method for a substation. Background technique [0002] Preventing electrical misoperation, referred to as anti-misoperation, is a basic requirement for substation operation control. The five-prevention function is the core function of preventing misoperation, that is, to prevent wrong opening and closing of circuit breakers, to prevent opening and closing of disconnectors or handcart contacts with load, to prevent power transmission with grounding wire (grounding switch), and to prevent live closing and grounding Switch (grounding wire), to prevent the function of entering the electrified interval by mistake. The anti-misoperation of the substation is usually realized by the microcomputer five-proof system. The five-proof system greatly guarantees the operation safety of the substation, but there are also certain deficiencies: it is neces...

AI Technical Summary

Problems solved by technology

The anti-misoperation of the substation is usually realized by the microcomputer five-proof system. The five-proof system greatly guarantees the operation safety of the substation, but there are also certain deficiencies: it is necessary to install computer keys, special coded locks, five-proof machines and other equipment, which increases the security of the substation. The type and quantity of equipment; the remote operation of the monitoring system needs to communicate with the five-defense system for confirmation, which increases the operating time; there is a situation of "going empty"

[0006] There is no regular comparison mechanism between the error prevention equipment at the station control layer and the equipment at the bay layer, and it is impossible to verify whether the blocking rules in the equipment at the station control layer and the equipment at the bay layer are consistent

During the commissioning stage of substation equipment, it is easy to cause omissions in the entry of five anti-blocking rules. There is no effective comparison method, and it can only be re-entered and overwritten.

There is a lack of unified configuration tools for error prevention at the station control layer, interval layer, and process layer, so the degree of automation is low and the workload increases

[0007] In addition, for the many anti-error systems in China at present, it is inevitable that many misoperations will occur when the user uses it for the first time, and in order to master the use of the system, it is often necessary to refer to the user manual and do a lot of operation exercises to master it.

The error prevention system also needs to increase or decrease the operation process to a certain extent according to the actual situation, otherwise there will be problems in use for the operators
