Problems solved by technology

The analysis shows that a large part of these accidents is caused by the fact that when the operator receives the operation ticket and operates the smart substation, he enters the wrong substation operation cabinet interval for operation, which leads to misoperation

Embodiment 1

[0026] Such as figure 1 As shown, a kind of intelligent substation anti-misoperation method of the present invention comprises the following steps:

[0027] Step 1: Retrieve the corresponding operation ticket from the database of the background server, and wait for the real-time sign image returned according to the operation sequence in the operation ticket;

[0028] Step 2: Before the operation, the operator first collects the image of the signboard at the current location, and sends the collected image of the signboard to the background server;

[0029] Step 3: The background server receives and processes the image of the signboard to identify the image information of the signboard, determines the current working position of the operator, and compares the position information with the position information required by the operation sequence;

[0030] Step 4: If the two location information are consistent, the background server sends an unlock command to the access control de...

Embodiment 2

[0065] This embodiment provides an intelligent substation error prevention operating system, which includes:

[0066] The image acquisition unit is used to acquire the signboard image of the operator before performing the operation task and send it to the image processing unit;

[0067] The image processing unit is used to perform image edge detection, upper and lower image segmentation and character segmentation on the acquired sign image;

[0068] The location information recognition unit is used to perform character judgment on the signboard characters through the neural network to determine whether the acquired signboard information is consistent with the target image information, and if they are consistent, send an unlock command, otherwise, keep the locked state.

Embodiment 3

[0070] This embodiment provides a computer-readable storage medium, on which a computer program is stored. When the program is executed by a processor, the steps in the method for preventing misoperation of a smart substation described in Embodiment 1 are implemented.

Abstract

The invention discloses an intelligent substation anti-misoperation method and system, and the method comprises the following steps: 1, a corresponding operation ticket is retrieved from a database of a background server, and thus waiting for a returned real-time signboard image according to the operation sequence in the operation ticket; 2, an operator collects a signboard image of the current position before operation, and sends the collected signboard image to a background server; 3, the background server receives and processes the signboard image to identify signboard image information, determines the working position of the current operator, and compares the position information with the position information required by the operation sequence; 4, if the two pieces of position information are consistent, the background server sends an unlocking command to the access control equipment, and an operator can execute subsequent operation; and 5, after the operation is completed, the operator sends a completion instruction to the background server, and then the step 2 to the step 4 are repeated until all the operation instructions in the operation order are completed.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to a method and system for preventing misoperation of an intelligent substation. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The substation is an important part of the power system, and it is responsible for important tasks such as voltage level conversion, input / removal of load, etc. Due to the large number of equipment such as circuit breakers, isolating switches, and grounding isolating switches in substations, misoperation accidents are very likely to occur if improperly operated, resulting in large-scale power outages, equipment damage, and even casualties. Therefore, it is of great significance to reduce or eliminate misoperations in substations. [0004] At present, the five-prevention system is widely used to prevent...
