Power grid accident grade judgment method and system based on multilayer data drilling

Abstract

The invention discloses a power grid accident grade judgment method and a power grid accident grade judgment system based on multilayer data drilling. The method comprises the steps of inputting geographic region layer data and operation standard layer data, and forming a reference database; acquiring power grid operation information layer data in real time, and screening power grid accident datain an abnormal state; judging the geographic region layer data, the power grid operation information layer data and the operation standard layer data of the power grid accident to be analyzed respectively; outputting an accident level according to a judgment standard in the operation standard layer data. According to the invention, a multilayer data drilling technology is adopted. The number of other data nodes which can be connected with any data node in the multi-layer data organization mode is obviously increased. Any data node under the multi-layer data structure can generate interactive connection with the upper-layer data, the same-layer data and the lower-layer data. Under the multi-layer data structure, the priority of data requests sent by the upper-layer data is high. Therefore,it is guaranteed that the execution efficiency of important data collection and response tasks is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of power grid accident level judgment, and in particular relates to a power grid accident level judgment method and system based on multi-layer data drilling. Background technique [0002] The level of power grid accident events is an important standard for handling accidents and abnormalities in dispatching operations. For power grid dispatching organizations, how to more efficiently statistically analyze basic data, combined with the real-time operating status of the power grid, and quickly and accurately determine the risk level of operational accidents has become a The key issues faced by dispatching agencies at all levels at present. Although some research and practical achievements have been made in the automatic system for determining the level of accident events, traditional data analysis and information mining are unable to cope with the increasingly large real-time operation data of the power grid,...

Problems solved by technology

Although some research and practical achievements have been made in the automatic system for determining the level of accident events, traditional data analysis and information mining are unable to cope with the increasingly large real-time operation data of the power grid, and its execution efficiency is limited by data analysis. The efficiency is low, and it is difficult to meet the requirements for judging the level of accident events in the real-time operation process
