Intelligent substation virtual loop comprehensive monitoring system based on multidimensional information acquisition

Abstract

The invention discloses an intelligent substation virtual loop comprehensive monitoring system based on multidimensional information acquisition. The monitoring system comprises a multidimensional information acquisition unit, a monitoring data processing unit and a visualization monitoring unit. The multidimensional information acquisition unit is used for obtaining and transmitting multidimensional comprehensive information to the monitoring data processing unit from a secondary device and a secondary virtual loop of a substation. The monitoring data processing unit is used for carrying out objectification modeling on the secondary device and the secondary loop of the intelligent substation, establishing a secondary virtual loop object and a network link topology connection model thereof, then carrying out automatic graph making of a second virtual loop graph and a network link graph on the multidimensional comprehensive information, and constructing and transmitting graphical interfaces displayed in a visualized manner to the visualization monitoring unit. The visualization monitoring unit is used for carrying out real-time on-line visualization display on the graphical interfaces via a human-computer interface. Thus, problems are solved that a secondary virtual loop of the intelligent substation is unobservable, unviewable and inconvenient to diagnose and maintain; operation and maintenance efficiency and automation level are increased.

Description

technical field [0001] The invention relates to a comprehensive monitoring system, in particular to an intelligent substation virtual circuit comprehensive monitoring system based on multi-dimensional information collection, which belongs to the technical field of power system automation. Background technique [0002] Compared with conventional substations, smart substations have the characteristics of digitization of signal secondary circuits, modeling of equipment information, and networking of information transmission. At present, the development of technologies such as operation, maintenance, monitoring and management of the secondary virtual circuit of smart substations at home and abroad is relatively lagging behind, especially in the monitoring, diagnosis and control of the secondary virtual circuit of smart substations. To adapt to the needs of the rapid development of smart substations; therefore, it is necessary to develop a comprehensive monitoring system for seco...
