Problems solved by technology

[0004] Due to the large number of protective pressure plates in the substation, this method has the problem of a large workload, and requires a large number of personnel to carry out inspections, and is prone to human negligence, resulting in omissions or misjudgments, resulting in failure to detect the protection of the pressure plate in time. Abnormal state, leaving potential safety hazards for power grid operation

Embodiment 1

[0043] figure 1 The flow chart of the method for checking the state of the substation protection pressure plate provided by Embodiment 1 of the present invention, this embodiment is applicable to the situation where the status of the protection pressure plate is checked in the substation, and the method can be executed by the substation protection pressure plate state verification device , including the following steps:

[0044] Step 110, collecting initial image data of the substation protection pressure plate.

[0045] In the power system, the protection pressure plate is also called the protection connecting piece or the tripping pressure plate. It is the bridge and link for the protection device to connect with the external wiring, and it is related to whether the protection function and the action outlet can work normally. The state of the protection pressure plate mainly includes throwing and withdrawing, that is, the protection pressure plate is in the throwing and wit...

Embodiment 2

[0057] figure 2 It is a flow chart of a method for checking the state of a substation protection pressure plate provided by Embodiment 2 of the present invention. This embodiment is a refinement based on the first embodiment, and describes in detail the processing of the initial image data of the substation protection plate. The method specifically includes the following steps:

[0058] Step 201, continuously collect image information of multiple substation protection pressure plates.

[0059] Step 202. Sorting the multiple image information according to the acquisition sequence to obtain initial image data.

[0060] In a specific implementation, for the initial image data of the substation protection plate, it is not limited to obtain the image information of a single substation protection plate as the initial image data required in the embodiment of the present invention, and multiple substations can also be acquired simultaneously according to actual needs The image inf...

Abstract

The invention discloses a transformer substation protection pressing plate state checking method, device and equipment and a storage medium. The transformer substation protection pressing plate state checking method comprises the steps of collecting initial image data of a transformer substation protection pressing plate; performing image enhancement processing and image morphology processing on the initial image data to obtain target image data; classifying the target image data by using a classifier to obtain state information of the transformer substation protection pressing plate, the state information comprising a label and a switch state of the transformer substation protection pressing plate; and when the state information is different from a preset state threshold value of the transformer substation protection pressing plate, sending out an abnormal signal. The classifier is used for recognizing the on-off state of the transformer substation protection pressing plate, and the on-off state is compared with the preset state threshold value, so that whether the transformer substation protection pressing plate is in the required on-off state or not can be effectively judged, the workload of an operator participating in checking the on-off state of the transformer substation protection pressing plate is reduced, and the safety of power grid operation is improved.

Description

technical field [0001] The embodiment of the present invention relates to a substation management technology, and in particular to a method, device, equipment and storage medium for checking the state of a substation protection pressure plate. Background technique [0002] There are a large number of relay protection devices running in substations. They can detect abnormal conditions in the power system, and when a fault occurs, isolate the fault point in time or send an alarm signal, which can effectively prevent the expansion of the fault range and ensure the safe and stable operation of the power grid. play an important role. [0003] In order to facilitate operators to judge and control the operating status of the relay protection device, a "function pressure plate" for realizing the protection function and an "exit pressure plate" for determining the result of the protection action are usually designed on the trip circuit. However, in actual operation, because the pres...
