Technical Field

The invention belongs to the field of transformer substation operation control, and particularly relates to an intelligent prompting system for transformer substation switching operation based on integrated monitoring.

Background

As an important support node of a strong smart grid, an intelligent substation gradually implements a series of intelligent operation and maintenance measures such as one-key sequential control operation, integrated monitoring, indoor robot inspection and the like, so as to improve the intelligent level of operation and maintenance operations of the substation.

Switching operation is the important work of transformer substation daily operation and maintenance, and is significant to the reliable switching of the guarantee big electric wire netting operation mode and provide safe maintenance environment for the maintainer. However, because the traditional transformer substation in the power grid system has large stock, new technologies such as one-key sequential control operation and the like are still in the experience accumulation stage, and at present, the switching operation is almost completed by manual operation. The operation accuracy is influenced by two factors, namely the accuracy of character checking of the operation ticket content and the on-site enamel cards and labels by operation and maintenance personnel and the accuracy of using a five-prevention unlocking key. The visual character check is a main means for avoiding wrong intervals and misoperation, but when the operation and maintenance personnel are too familiar with the equipment for a long time, the wrong intervals and misoperation are very easy to occur under the conditions of poor sight, poor spirit and carelessness. Most of misoperation can be avoided by the five-prevention locking, but due to the operation reliability of the equipment and the self problems of the five-prevention locking, the unlocking is careless, and major operation accidents are often caused easily.

With the wide construction of intelligent substations and the application of new technologies and new equipment in the substations, the intelligentization level of the substations is greatly improved, but the information isolation among different systems restricts the exertion of the whole functions and the development of high-level application. In order to realize the acquisition of panoramic data of the transformer substation and standardize the system architecture of the intelligent transformer substation, the national power dispatching control center organizes and provides the concept of an integrated monitoring system so as to solve the problem of difficult information interaction of different systems in the substation and improve the system integration level and the function fusion level. The integrated monitoring system expands the monitoring and control of various auxiliary application systems, metering systems and state monitoring systems on the basis of the traditional monitoring system. The safety of information interaction between different systems is enhanced through an internal partitioning technology, a firewall technology and a longitudinal encryption authentication technology. The transformer substation background monitoring system is located in a safety zone I, system information such as a production management system, a robot system, video monitoring and communication with other main stations is located in a safety zone II, and communication is conducted with the safety zone I through a firewall. The construction of the integrated monitoring system can greatly improve the intelligentization, automation and informatization levels of work such as transformer substation operation monitoring, operation and control, information comprehensive analysis and intelligent alarm, operation management, auxiliary application and the like, and reduce the complexity of respectively inquiring information among different systems by personnel, so that the integrated monitoring system not only is the construction direction of an intelligent transformer substation, but also is the development direction of the technical transformation of the traditional transformer substation.
