Abstract

An embodiment of the invention discloses a power grid statistics data derivation calculating method and a power grid statistics data deviation system based on a hierarchical storage model. The method and the system are used for settling technical problems of high artificial maintenance workload and easy omission through an artificial definition formula method, frequent modification and testing to a data processing module and stable system operation incapability in a special statistics calculation method by means of a special program. The method provided by the embodiment comprises the steps of constructing a power grid hierarchical relation model according to acquired power grid model data; defining and generating a universal calculation formula according to the power grid hierarchical relation model, wherein the universal calculation formula comprises a calculation factor, a result factor and a calculation logic; acquiring all records of an associated list domain of the calculation factor, performing deviation calculation on all the records according to the calculation logic, and writing an obtained calculation result into a model data position which is associated with the result factor.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a method and system for deriving calculations of statistical data of power grids based on a hierarchical storage model. Background technique [0002] At present, the dispatching automation system not only needs to monitor the operation status of each equipment, but also needs to monitor the statistical data of the power grid operation. The important statistical index data monitored include various loads of the power grid, the total output of regions and stations, and the output of different power sources. Currently, The domestic dispatching automation system processes these data by manually defining formulas or using proprietary programs for special statistical calculations. Although the rules of data processing using manually defined formulas are flexible, as the power grid model changes, all relevant formulas need to be modified, and the workload of manual maintenance incre...
