Protection pressing plate state identification method based on AI technology

Abstract

The invention discloses a protection pressing plate state identification method based on an AI technology. The method comprises the following steps: obtaining on / off state information of each pressingplate switch in the operation state of a protection pressing plate as first state information; obtaining the on / off state information of each pressing plate switch in the maintenance state of the protection pressing plate as second state information; acquiring the pressing plate image of a to-be-identified protection pressing plate; cutting the pressing plate image into a plurality of independentpressing plate switch images; identifying the on / off state of each pressing plate switch image as third state information; and judging the state of the protection pressing plate based on the first state information, the second state information and the third state information. The method achieves the purpose of automatically judging the state of the protection pressing plate, and reduces the riskof manual judgment.

Description

technical field [0001] The invention belongs to the field of electric power, and in particular relates to a method for identifying the state of a protective pressure plate based on AI technology. Background technique [0002] The regulations stipulate that unprotected operation of power equipment is prohibited, and the wrong switching of the relay protection pressure plate will cause the protection to refuse to operate or malfunction, which will expand the scope of fault removal and even cause serious power grid accidents. Therefore, in the actual inspection work, it is necessary to frequently check the switching status of the protective pressure plate, and verify whether the switching status of the protective pressure plate is compatible with the current operation mode of the primary equipment. However, there are many types and manufacturers of relay protection equipment, and the names of the protective pressure plate are not uniform. The functions are different. There are ...

[0002] The regulations stipulate that unprotected operation of power equipment is prohibited, and the wrong switching of the relay protection pressure plate will cause the protection to refuse to operate or malfunction, which will expand the scope of fault removal and even cause serious power grid accidents

Therefore, in the actual inspection work, it is necessary to frequently check the switching status of the protective pressure plate, and verify whether the switching status of the protective pressure plate is compatible with the current operation mode of the primary equipment. However, there are many types and manufacturers of relay protection equipment, and the names of the protective pressure plate are not uniform. The functions are different, and there are large differences in the operation and withdrawal of the pressure plate corresponding to different power grid operation modes. The logical relationship between the operation and withdrawal state and the protection action is complicated. The method of manually checking the state of the pressure plate is easy to cause errors in the operation and withdrawal of the pressure plate due to visual errors and memory errors.
