Intelligent electric meter clustering classification method for electric meter replacement

Abstract

The invention discloses an intelligent electric meter clustering classification method for electric meter replacement. Relates to the field of ammeter operation. At present, the electric meter replacement plan is not scientific. The method comprises the following steps: generating a space-time distribution matrix of all ammeters according to a list of ammeters to be replaced; calculating the local density of the data points and the distance from the data points to the points with higher density by adopting a rapid clustering algorithm based on a density peak value; according to the distribution of the local density and the high-density point distance, generating a clustering decision diagram of the electricity meter, and determining each clustering center; determining the category to which the data points of the remaining electricity meters belong according to the distance between the data points of the remaining electricity meters and each clustering center to obtain each electricity meter cluster; and for each electricity meter cluster, considering constraint conditions, and finally generating an electricity meter replacement daily plan. According to the technical scheme, the space-time similar electric meter clusters are extracted by combining the electric meter regional distribution characteristics and the time adjacency characteristics, the calculation complexity of the optimization model is effectively reduced, and electric power system personnel can make a more reliable and more scientific electric meter replacement plan.

Description

technical field [0001] The invention relates to the field of electric meter operation and maintenance, in particular to a cluster classification method for smart electric meters used for electric meter replacement. Background technique [0002] As a terminal hub connecting smart grids and power consumers, smart meters are responsible for important functions such as energy data collection, metering, transmission and event recording. They are the only basis for electricity bill settlement, so they have become an indispensable part of smart grids. , its operational health level will directly affect the fairness and accuracy of electricity sales. With the widespread installation and application of smart meters, the maintenance of smart meters has become one of the important businesses of power grid companies. The maintenance of electricity meters generally includes electricity meter replacement, operation sampling inspection, on-site inspection, on-site inspection and other serv...
