Description

Technical Field

[0001] The present invention relates to the technical field of substation automation operation and maintenance, and in particular to a substation automation operation and maintenance method based on an intelligent operation and maintenance gateway. Background Art

[0002] In the current operation and maintenance of substation automation equipment, most of the operation and maintenance management still adopts the traditional mode, which is isolated and passive, and it is difficult to ensure the smooth, orderly and stable operation and maintenance of automation equipment. The main manifestations are as follows.

[0003] (1) It mainly relies on manual processing, and the operation and maintenance personnel are often in a passive position. The operation and maintenance personnel handle the faults according to the errors reported by the users of the automation-related information system. Once the operation and maintenance manpower is tight when the problem occurs, there will not be enough personnel to carry out the operation and maintenance work, making it difficult to locate and solve the problem in a timely and accurate manner, which will seriously affect the normal operation of the automation system.

[0004] (2) There is no perfect automated monitoring system, and the data between devices lacks effective integration and analysis, so the early warning function cannot be realized. The work can only be triggered after the equipment alarm. The operation and maintenance personnel can often only handle the fault after the fault occurs. This not only increases the workload of the operation and maintenance personnel, but also greatly affects the stable operation of the entire substation system.

[0005] With the rapid development of science and technology in my country and the gradual transformation of low-carbon economic mode, smart grid technology is becoming more and more perfect, and smart substations have entered the stage of comprehensive promotion and construction. Compared with traditional substations, smart substations have many new technologies and solutions such as equipment types, communication standards, data transmission, and application support, which bring new vitality to substation operation and maintenance. Many achievements have been made in data flow transmission, secondary equipment status and intelligent monitoring of smart substations, but there are few studies on the intelligent operation and maintenance of automation equipment such as motion devices, measurement and control devices, switches and monitoring background. Based on the virtual local area network, a comprehensive digital model of the comprehensive data flow of intelligent electronic equipment in the substation is established. The fuzzy evaluation method is used to find the key factors that play a role in the accuracy of the status of secondary equipment in smart substations, and the evaluation is carried out to give the calculation steps of the evaluation. The storage method of the activation information of the Internet of Things and the secondary equipment of smart substations is improved, and the information of a single automation device is configured separately without unified operation and maintenance. The working mechanism of the monitoring problem of smart substations is evaluated, but the standardization of the operating parameters of the measurement and control device is not considered.
