Abstract

The invention discloses a distribution network running state assessing and pre-warning method based on big data. An assessing and pre-warning mechanism, which is mainly used for monitoring the current running state of a distribution network to guarantee safe running of the distribution network, is mainly composed of a data processing module, a running state assessing module, a risk pre-warning module, an operating control module, and the like. First, given index parameters are synthesized through principal component analysis; then, a function relation between the comprehensive score and each index data is mined based on the algorithm thought of gene expression programming; and finally, the current running state data of a distribution network is input to the function relation, the current running state risk level of the distribution network is assessed according to the calculation result, and feasible reference opinions are given. Thus, users and decision makers are helped to better plan and manage the whole distribution network, and the distribution network can run more efficiently and more safely.

Description

Technical field [0001] The invention relates to an evaluation and early warning method for the operation state of a distribution network, which is mainly used to solve the problems of the evaluation and early warning of the operation state of the distribution network, and belongs to the field of power information security. Background technique [0002] The distribution network is an important part of the power system. With the development of social economy and the improvement of people's living standards, people have put forward higher requirements for the construction and management of the distribution network. However, in the traditional evaluation of the operation status of the distribution network, limited by narrow data collection channels or low data integration and processing capabilities, it is difficult for researchers to dig out more valuable information. Nowadays, due to the popularization and application of application systems such as distribution automation and elect...
