Power grid operation brief report data analysis method

The invention provides a power grid operation brief report data analysis method. The power grid operation brief report data analysis method comprises the steps of automatically grasping structural data in power grid operation brief report data from the release address of the power grid operation brief report data, and performing structural recognition to nonstructural data in the power grid operation brief report data; preforming three-dimension extraction to the structural data in the power grid operation brief report data, wherein the three dimensions include regional power grid wind power data, regional power grid connecting line power supply data and regional power grid power generation and load data; performing trend analysis to the historical data of each index in each dimension to obtain a historical data curve corresponding to each index. The method provided by the invention can perform historical observation and trend analysis to a certain index of the structural data in a historical period, can perform structural analysis to power grid related events in t power grid operation brief reports and can also perform analysis to the structural data from other dimensions such as power plants and equipment.
