Research on Grid State Portrait Technology and Its System Realization

Based on the traditional user portrait technology and concept, this paper extracts various indicators that reflect the characteristics of grid operation state from the main aspects of grid operation to construct the grid state portrait label system and label generation method, establishes the grid state portrait analysis model, and evaluates the grid state trend. On this basis, the grid state portrait application system is designed and implemented, and the in-depth analysis of the grid state portrait and operation data is realized by means of an intuitive comprehensive display method. The practical application results show that the system can intuitively reflect the grid operation situation from multiple dimensions, discover and display data rule related to equipment or grid, which can provide technical support for power grid operators to conduct monitoring, take preventive measures and make decision for power grid operation.
