System and method for preventing misoperation of change-over switch of transformer substation

Abstract

The invention discloses a system and a method for preventing misoperation of a change-over switch of a transformer substation. The system comprises an image shooting device and a monitoring main station, wherein the image shooting device and the monitoring main station are in communication connection through a network or a data line; the image shooting device can acquire image information of a protection screen of the change-over switch and transmits the image information to the monitoring main station; the monitoring main station can receive the image information, analyze, process and acquire the information of the change-over switch according to an image, and then a change-over switch model and a change-over switch state library are built sequentially, so that querying and calling are facilitated; according to a grid management requirement, a correct casting and cancelling state of the change-over switch at present or after operation is generated; according to the state and the image information, a synthetic picture is synthesized automatically; and the synthetic picture is used for guiding an operator to control the switching of the change-over switch. The system has the advantages as follows: the routing inspection efficiency of the state of the change-over switch of the transformer substation is improved, and the operator is prevented from operating the change-over switch mistakenly.

Description

technical field [0001] The invention relates to a system and method for preventing misoperation of a transfer switch in a substation Background technique [0002] The correct switching on and off of the transfer switch in the substation in the power system is related to the safe operation of the power system. Once it is switched on or off by mistake, it will cause the protection device and the switch to malfunction or refuse to operate, thereby endangering the safety of the power grid. Therefore, this problem has always been a problem. It is an important problem to be solved urgently in substation management and operation. With the expansion of power grid scale and the development of protection technology, the number of transfer switches in substations has doubled, thus putting forward higher requirements for its management.

[0002] The correct switching on and off of the transfer switch in the substation in the power system is related to the safe operation of the power system. Once it is switched on or off by mistake, it will cause the protection device and the switch to malfunction or refuse to operate, thereby endangering the safety of the power grid. Therefore, this problem has always been a problem. Important problems to be solved urgently in substation management and operation

[0003] At present, the inspection of the position of the transfer switch in the substation is still done manually. The main anti-mistake measures rely on strict rules and regulations. The switching status of the substation transfer switch depends entirely on the responsibility and personal quality of the operator, and there is no means of anti-mistake. Therefore, it is very easy to misuse the transfer switch of the substation, which will bring huge losses to the power system.
