Substation Switching Operation Remote Compulsory Monitoring System

Abstract

The invention discloses a remote compulsory monitoring system for substation switching operation. In the centralized control center, the operation ticket is transferred to the computer key through a simulated preview, and the operation ticket is displayed in the client computer of the centralized control center. After the scene, notify the guardians of the centralized control center, the guardians will authorize the operation of the on-site computer keys through wireless communication on the client side of the centralized control center, and the unlocking keys of the operators will be unlocked according to the instructions issued by the guardians of the centralized control center. The authorized operation steps carry out the on-site unlocking operation. After the operation is completed, the operation result is automatically sent back to the centralized control center. After the guardian of the centralized control center confirms, after the confirmation is correct, the next operation command is sent, and so on. Until the entire operation ticket is completed, the operation After the completion, the operation results of the computer key are transferred to the system as historical data to save, so as to ensure that every step of the operation of the on-site operator is carried out under the authorized supervision of the guardian of the centralized control center.

Description

technical field [0001] The invention belongs to the technical field of substation automatic operation, and in particular relates to a remote compulsory monitoring system for substation switching operation. Background technique [0002] With the rapid development of the power grid, the number of substations and substation equipment has doubled, and the duty mode of substations has gradually changed from manned to unattended or less manned, and the single-station management mode has gradually changed to the centralized control station management mode. The unattended centralized control operation of the power grid is changing from the management mode of "large and small" to the management mode of "regional centralized control". or modes that are set independently of each other. The operation of electrical equipment in the process of changing from any state of operation, standby, and maintenance to another state is called switching operation. The scale of the power grid is get...

AI Technical Summary

Problems solved by technology

[0004] 1. The cost is too high: the system costs hundreds of thousands for each installation site, and there are too many external devices, which requires a lot of maintenance in the later stage;

[0005] 2. Low cost performance: In the early remote monitoring system, the image was unstable, and the video overview was relatively small;

[0006] 3. Single performance: the mandatory locking function of switching operation cannot be realized, and only the monitoring in the station area of ​​a single substation can be performed. For the current large-scale centralized control construction of substation operation, the operation of substations with few people on duty and unattended substations has certain advantages. great limitations;

[0007] 4. Poor reliability: Some single-person remote image monitoring systems perform remote monitoring through voice and image, which is unstable, affected by environmental conditions, emotions and many other factors, and the personnel are relatively random. After a failure, online monitoring cannot be implemented Personnel operation
