[0050] The embodiments of the present invention provide a substation fault early warning method, device, electronic device and storage medium, which are used to solve the technical problems of low substation inspection efficiency and difficulty in effectively warning substation equipment failures.

[0051] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] See also Figure 1 , Figure 1 A flowchart of a method for early warning of a substation fault provided by an embodiment of the present invention.

[0053] In one embodiment, a substation fault early warning method provided by the present invention may include the following steps:

[0054] Step 101, obtaining operation data and topology data of substation equipment.

[0055] A substation is a place in the power system where voltage and current are transformed, electrical energy is received and distributed.

[0056] Step 102 , using the operation data and the topology data, and performing three-dimensional modeling based on a pre-established three-dimensional modeling model, to generate a three-dimensional model of the substation equipment.

[0057] In the embodiment of the present invention, the three-dimensional model of the substation can be generated based on the pre-established three-dimensional modeling model by acquiring the operation data and topology data of the substation equipment.

[0058] Step 103: Identify the equipment to be inspected from the three-dimensional model.

[0059] Step 104: formulate a fault inspection route for the equipment to be inspected based on the three-dimensional model.

[0060] In the embodiment of the present invention, the equipment to be inspected can be marked in the three-dimensional model, and a fault inspection route can be formulated according to the equipment to be inspected. The specific fault inspection route can be formulated according to actual conditions, and the embodiment of the present invention does not specifically limit it.

[0061] Step 105, verifying the fault inspection route.

[0062] After the fault inspection route is formulated, the fault inspection route can be verified to determine whether the fault inspection route meets the inspection requirements.

[0063] Step 106, when the verification is passed, the preset inspection equipment is controlled to inspect the equipment to be inspected along the inspection route to obtain the inspection result.

[0064] In the embodiment of the present invention, the inspection device may be an inspection drone or an inspection robot, and the embodiment of the present invention does not specifically limit the inspection device.

[0065] Step 107, determining the fault information of the substation equipment according to the inspection results, and issuing an early warning based on the fault information.

[0066] After the inspection is completed, the fault information of the substation can be determined according to the inspection results to generate an early warning signal corresponding to the fault information and issue an early warning.

[0067] In one example, the fault information may include the fault point, fault type, and fault level of the faulty equipment in the substation.

[0068] The embodiment of the present invention establishes an inspection route through a three-dimensional model, and then conducts inspections according to the inspection route to determine the fault of the substation, and accurately locate the fault to ensure the normal operation of the substation equipment, thereby improving the inspection efficiency, achieving effective early warning of substation equipment failures, and saving human resources.

[0069] See also Figure 2 , Figure 2 A flowchart of a method for early warning of a substation failure provided by another embodiment of the present invention. In an embodiment of the present invention, the method for early warning of a substation failure may include the following steps:

[0070] Step 201, obtaining operation data and topology data of substation equipment.

[0071] Step 202: extract characteristic data from the topology data, and filter abnormal operation data from the device data.

[0072] Step 203: Based on the feature data, a three-dimensional scene model of the substation equipment is established according to the three-dimensional modeling model.

[0073] Step 204: determining abnormal operation points in the substation equipment based on the abnormal operation data.

[0074] Step 205: Add a to-be-inspected label at a position corresponding to the abnormal operation point in the three-dimensional scene model of the substation equipment to generate a three-dimensional model.

[0075] In an embodiment of the present invention, feature data in the topological data of the substation equipment can be extracted, a three-dimensional scene model of the substation can be established based on the feature data and the three-dimensional modeling model, and abnormal operation data in the equipment data can be screened. Based on the abnormal operation data, abnormal operation points in the substation equipment are determined, and labels to be inspected are added at positions corresponding to the abnormal operation points in the three-dimensional scene model to generate a three-dimensional model.

[0076] In one example, the 3D model can be established by the following steps:

[0077] S1, obtaining topological data samples of substation equipment samples of various topological types and corresponding three-dimensional model samples.

[0078] S2, extracting device feature data from topology data samples.

[0079] S3, extracting model feature data corresponding to the device feature data from the three-dimensional model sample.

[0080] S4, using the device feature data as input data and the model feature data as output data, training the preset network to obtain a trained network.

[0081] S5, through the trained network, the process of establishing a three-dimensional scene model of the substation equipment according to the output data is learned to generate a three-dimensional modeling model.

[0082] In a specific implementation, topological data samples and corresponding three-dimensional model samples of substation equipment samples of various topological types can be obtained, and then equipment feature data can be extracted from the topological data samples, and model feature data corresponding to the equipment feature data can be extracted from the three-dimensional model samples. The equipment feature data is used as the input data of the model, and the model feature data is used as the output data of the model. The preset network is trained to obtain a trained network, and then the process of establishing a three-dimensional scene model of the output data is learned through the trained network to generate a three-dimensional modeling model.

[0083] Step 206: Identify the equipment to be inspected from the three-dimensional model.

[0084] In the embodiment of the present invention, the equipment to be inspected includes equipment corresponding to the abnormal operating point in the three-dimensional model.

[0085] Step 207: Formulate a fault inspection route for the equipment to be inspected based on the three-dimensional model.

[0086] In one embodiment, step 207 may include the following steps:

[0087] S71, determining the three-dimensional coordinates of the tag to be inspected in the three-dimensional model.

[0088] S72, formulate a fault inspection route according to the three-dimensional coordinates.

[0089] In a specific implementation, a tag to be inspected may be configured for each device to be inspected. Each tag to be inspected has three-dimensional coordinates corresponding to the location of the device to be inspected. A fault inspection route for the device to be inspected may be developed through the three-dimensional coordinates.

[0090] In an example, the fault inspection route can be formulated based on the relative distance between the three-dimensional coordinates, or based on the mutual influence relationship between different devices to be inspected. It can be specifically formulated based on actual inspection needs, and the embodiment of the present invention does not specifically limit this.

[0091] Step 208, verifying the fault inspection route.

[0092] In one embodiment, step 208 may include the following steps:

[0093] S81, simulate inspection of the fault inspection route in the three-dimensional model, monitor the simulated inspection process, and obtain monitoring results.

[0094] S82, if the monitoring result is that all the equipment to be inspected have completed the inspection, and the inspection equipment is not disturbed or damaged during the inspection, it is determined that the fault inspection route has passed the verification.

[0095] In the specific implementation, a fault inspection route can be used to perform simulated inspections in a three-dimensional model, and the simulated inspection process can be monitored to obtain monitoring results; if, based on the monitoring results, it is determined that the inspection is to be performed according to the fault inspection route, all equipment to be inspected can be inspected, and the inspection equipment is not disturbed or damaged during the inspection process, then the fault inspection route meets the requirements, otherwise it does not meet the requirements; if the fault inspection route does not meet the requirements, the fault inspection route is adjusted according to the monitoring results and the model data of the three-dimensional model until the fault inspection route meets the requirements.

[0096] Step 209, when the verification is passed, the preset inspection equipment is controlled to inspect the equipment to be inspected along the inspection route to obtain the inspection result.

[0097] Step 210, determining the fault information of the substation equipment according to the inspection results, and issuing an early warning based on the fault information.

[0098] After the inspection is completed, the fault information of the substation can be determined according to the inspection results to generate an early warning signal corresponding to the fault information and issue an early warning.

[0099] Furthermore, in one embodiment, the substation fault early warning method of the present invention may also include: performing routine inspections on conventional equipment in the substation equipment except the equipment to be inspected to obtain routine inspection results; and issuing routine early warnings based on the routine inspection results.

[0100] The present invention establishes an inspection route through a three-dimensional model, and then conducts inspections according to the inspection route to determine the fault of the substation, and accurately locates the fault to ensure the normal operation of the substation equipment, thereby improving the inspection efficiency, achieving effective early warning of substation equipment failure, and saving human resources.
