Station area electricity utilization monitoring method based on bad electric quantity data identification

Abstract

The invention provides a station area electricity utilization monitoring method based on bad electric quantity data identification. The station area electricity utilization monitoring method based on bad electric quantity data identification comprises the following steps of: calculating a line loss rate according to the acquired meter-reading electric quantity data of a station area during a time period, and initially judging whether an abnormal electricity utilization phenomenon exists or not; in the case that the abnormal electricity utilization phenomenon is found, turning to a B-spline function identification method, and identifying the line loss rate, and abnormal data in the daily electricity consumption data of each user; and locating suspicious electricity-stealing users by comparing the abnormal time periods corresponding to the line loss rate data of the power grid of the station area and the daily electricity consumption data of each user. The method provided by the invention only needs the meter-reading electric quantity data of the power grid of the station area, as well as is low in requirements on original data, strong in engineering applicability, and easy to be popularized and applied in the existing power grids of station areas in China. The method provided by the invention is adequate in theoretical basis and good in identification effect by identifying and locating the suspicious electricity-stealing users based on a B-spline function.

Description

technical field [0001] The invention belongs to the technical field of electricity consumption monitoring and analysis in electric power systems, and in particular relates to a power consumption monitoring method in a station area based on bad electricity data identification. Background technique [0002] The management line loss of my country's power grid has remained high for a long time, which has brought huge economic losses to the power sector. Among them, electricity theft or abnormal power consumption is one of the main reasons for the high management line loss. Due to the diversification of electricity theft methods and the low level of anti-theft technology, the problem of electricity theft has been plagued by power supply departments at all levels. Stealing electricity not only seriously disrupts the order of power supply and utilization, but also seriously affects the power quality and reliability of the power grid in the station area. Therefore, how to implement...

Problems solved by technology

The main disadvantage of this method is that it is required to collect the voltage, current and power data of all users, and the grid data of the station area is known, which has high requirements for the data platform and poor engineering practicability

At present, most load data collection terminals in my country can only provide meter reading electricity data, which limits the applicability of the above method
