Abstract

The invention provides a high-speed train electric energy quality data processing system comprising a data acquisition unit, a data preprocessing unit, a normalization unit, a clustering unit, an abnormal point detection unit and an electric energy quality database. The data preprocessing unit screens out the electric energy quality data in case of only one train operating on the supply arm according to the electric energy quality data in case of train operation and the operation time of the high-speed train on the supply arm and preprocesses the electric energy quality data. The clustering unit clusters the sample electric energy quality data after normalization processing so as to acquire electric energy quality data classes of different train types. The abnormal point detection unit performs abnormal point detection on the electric energy quality data after clustering processing so as to obtain the abnormal point set and transmit the abnormal point set to the electric energy qualitydatabase to be stored.

Description

technical field [0001] The invention relates to the technical field of power quality monitoring, in particular to a high-speed rail power quality data processing system. Background technique [0002] Electrified high-speed railway locomotives are nonlinear and impact loads, which mainly affect power quality such as negative sequence and harmonics to the power grid. At the same time, different types of locomotives cause different power quality characteristics of the power grid, especially harmonic characteristics. These not only have adverse effects on other equipment in the grid, but also pose a threat to the stability and reliability of its own operation. The electric locomotive of the electrified railway is a high-power single-phase rectifier load with great fluctuations, and due to the various states of acceleration, coasting, and braking of the train during operation, as well as the slope of the line, the radius of the curve, the weather conditions, and the driver's oper...
