Abstract

The invention belongs to the technical field of electric energy quality analysis of high-speed railway lines and provides an electric energy quality data-based high-speed railway line vehicle operating time period determination method, a device and a storage device. The electric energy quality data-based high-speed railway line vehicle operating time period determination method mainly comprises the following steps that: active power in the electric energy quality monitoring data of a high-speed railway line is extracted and normalized; and the probability distribution of the normalized activepower is calculated, and a power interval corresponding to a maximum probability value is selected, and time periods outside the power interval are selected and adopted as the vehicle operating time periods of the high-speed railway line. Based on the above steps, the high-speed railway line vehicle operating time period determination method provided by the present invention can accurately and quickly identify the vehicle operating time periods of the high-speed rail line.

Description

technical field [0001] The invention relates to the technical field of power quality analysis of high-speed railway lines, and in particular to a method and equipment for judging the time period of a high-speed railway line based on power quality data. Background technique [0002] With the acceleration of the construction of the national electrified railway network, more and more electric railway traction stations have been built and operated, making the scale of the current monitoring points and monitoring network increasingly large, and the monitoring data is increasing geometrically. In the face of massive power quality monitoring data, it is urgent to dig out the potential information hidden in the data to improve the intelligence of the power grid. High-speed railway is a kind of load with impact, fluctuation and intermittent in the power grid. It has high requirements on the power supply capacity and reliability of the power grid, and after connecting to the power gri...
