Method and system for identifying household substation relationship in station area based on load characteristics of start-up and stop of electrical appliances

Abstract

The invention discloses a method and a system for identifying the household substation relationship in a station area based on the load characteristics of the start-up and stop of electric appliances. The load feature extraction in this method no longer depends on the full node in the station area, and the reading range can be adjusted and identified accordingly. The ownership of the table relative to the main table, and then repeat the operation on other sub-tables, you can get the household change relationship of all sub-tables in the entire identification domain. This method is no longer limited by the bandwidth problem of the HPLC network, and can be effectively applied to the identification of household-change relationships in the Datai District network. Moreover, by comparing the load characteristic maps generated based on the start-stop characteristics of specific electrical appliances to identify the relationship between households and transformers, due to the characteristics of the start-stop characteristics of specific appliances, it is easy to quickly and accurately identify them from all load data, thereby The accuracy and recognition efficiency of the recognition result are improved.

Description

technical field [0001] The present invention relates to the technical field of power grid station area identification, in particular to a method and system for identifying the household-to-substation relationship of a station area based on the load characteristics of electric appliances starting and stopping. Background technique [0002] Household transformer relationship is the basic data of the power grid, which is widely used in power grid management. Its accuracy directly affects the management function of the power grid. If there is an error in the household transformer relationship, then the line loss management, which is one of the core management functions of the power grid, cannot be discussed. rise. However, in actual construction, some station districts had incomplete or incorrect entry of household change relations from the very beginning, and some station districts had accurate household change relations at the beginning, but in the subsequent construction (suc...
