The remote control power grid device may be a device in a power distribution network where a user can remotely control an operation state through a terminal, and by way of example, the remote control power grid device may be a transformer, a high-voltage switching device, a low-voltage switching device, a circuit breaker, and the like. The remote control power grid device to be operated may be a remote control power grid device ready for detection of a malfunction. The operation instruction may be a command to operate a remote control grid device.
Specifically, in the power grid line diagram, remote control power grid equipment to be operated and an operation instruction are obtained. Acquisition means include, but are not limited to: user input, mouse clicks, or data grabbing, etc., to which embodiments of the invention are not limited.
In one example, in the power grid line graph, a remote control power grid device to be operated is selected by clicking a pattern identifier of the device in the power grid line graph through a mouse, and an operation instruction sent by a user to the remote control power grid device is acquired through data grabbing.

In one example, the target device is a high-voltage switch device, receives an operation instruction of the high-voltage switch device sent by a user, detects whether the user has operation authority, and determines remote control power grid equipment to be operated and the operation instruction according to the operation instruction of the high-voltage switch device, wherein the user has the operation authority identification of the high-voltage switch device.
By detecting whether the user has operation authority, when the user has the operation authority, the remote control power grid equipment to be operated and the operation instruction are determined according to the operation instruction of the target equipment, and by checking the operation authority, the authority of the user operable equipment can be checked, so that misoperation of the user is prevented, and the reliability of power grid misoperation detection is improved.
Optionally, determining the remote control power grid device to be operated and the operation instruction according to the operation instruction of the target device includes: acquiring a user identifier of a user; inquiring the equipment identification corresponding to the user identification in the corresponding relation between the preset user identification and the operable equipment identification according to the user identification of the user; acquiring a device identifier of a target device; when the equipment identifier corresponding to the user identifier is consistent with the equipment identifier of the target equipment, the remote control power grid equipment to be operated and the operation instruction are determined according to the operation instruction of the target equipment.

The device identifiers can be information for identifying remote control power grid devices, and the device identifiers are in one-to-one correspondence with the devices.

Specifically, a preset corresponding relation between the user identifier and the operable device identifier is stored in a database, the user identifier of the user is obtained, the device identifier corresponding to the user identifier is queried through a character string searching algorithm in the database storing the corresponding relation between the user identifier and the operable device identifier according to the user identifier of the user, the device identifier of the target device is obtained, whether the device identifier corresponding to the user identifier is consistent with the device identifier of the target device is compared, if the device identifier corresponding to the user identifier is consistent with the device identifier of the target device, the target device is determined to be the remote control power grid device to be operated, and an operation instruction of the target device is determined to be the operation instruction of the remote control power grid device to be operated.
In one example, the corresponding relationship between the preset user identifier and the operable device identifier is that the user 1 corresponds to the device 1, the corresponding relationship may be stored in the database 1, the user identifier of the user is obtained as the user 1, and in the database 1, the device identifier corresponding to the user 1 is queried as the device 1 through the string search algorithm. The method comprises the steps that target equipment is high-voltage switch equipment, equipment identification of the high-voltage switch equipment is obtained to be equipment 1, equipment identification corresponding to user identification is consistent with equipment identification of the target equipment, the high-voltage switch equipment is determined to be remote control power grid equipment to be operated, and an operation instruction of the high-voltage switch equipment is determined to be an operation instruction of the remote control power grid equipment to be operated.
