Abstract

The invention discloses a power grid development-oriented multivariate information mining analysis method and system. The method comprises the steps of obtaining related influence data in a power gridsystem operation scene; preprocessing the data to obtain a multivariate information integrated data set of internal and external data; performing time-space correlation degree classification analysison all the data sources, and determining distribution difference and characteristics of resources such as loads and power supplies in different operation scenes in space dimension; determining space-time correlation characteristics of power grid operation information in various external environments; and determining and adjusting a power grid planning and reconstruction architecture scheme. Dataintegration, data preprocessing and data analysis are carried out according to internal and external multivariate information data during power grid operation, an effective information set is formed according to power grid development diagnosis indexes, and the data analysis efficiency is improved by adopting parallel computing; the whole power grid development process is studied, and data space-time correlation characteristics and dynamic change rules are obtained through data mining, so that a power grid planning and reconstruction architecture scheme is determined and adjusted.

Description

technical field [0001] The invention relates to the technical field of power grid analysis, in particular to a multivariate information mining analysis method for power grid development. Background technique [0002] With the continuous development of the power grid, it is very important to analyze the temporal and spatial correlation characteristics of the power grid power flow from more perspectives in view of the temporal and spatial power flow changes of the power grid. At present, the research on power flow characteristics focuses on fault diagnosis, and there are few studies on the steady-state operation conditions, such as sensitivity, fluctuations and other characteristics that need to be further studied. In the process of power grid development, the power grid evaluation system is also constantly updated, accelerating its evolution to a comprehensive, intelligent, and practical direction. Carrying out data-driven research on power grid intelligent diagnosis systems ...
