Embodiment Construction

[0048] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention may be implemented in a variety of different ways defined and covered below.

[0049] Such as figure 1 As shown, the first embodiment of the present invention provides a station area identification method. The identification of the station area power supply network based on load jump identification technology specifically includes the following steps:

[0050] Step S1: Apply data collection to all sub-meters and total tables in the identification domain to obtain the steady-state value of the load, and generate a jump curve of the steady-state value of the load;

[0051] Step S2: The load steady-state value jump curves of all sub-meters are matched with the load steady-state value jump curves of the total table for load jump characteristics, and the ownership of the sub-meters with load jumps is obtained according to the matching resu...

Abstract

The invention discloses a transformer area identification method and a method for constructing transformer area line topology. According to the invention, a load jump identification technology is adopted; load values of all nodes in a transformer area power supply network are collected, and load jump curves of each node can be formed; the load jump curves of all the sub-meters and the load jump curve of the general meter are subjected to load jump characteristic matching, so that the judgment of the corresponding electric meter mounting relationship is realized, the transformer area identification and transformer area line topology construction are realized, the influence of line loss power can be eliminated, and the identification accuracy is improved.

Description

Technical field [0001] The present invention relates to the technical field of smart grids, in particular, to a method for identifying a station area, and in addition, to a method for constructing a station area line topology. Background technique [0002] In the power system, the station area refers to the power supply range or area of ​​the transformer, which is a term for the economic operation and management of electric power. Therefore, accurate and effective identification of the station area can significantly improve the efficiency of power management. [0003] However, the existing method of station area identification and the method of constructing station area line topology are based on the power supply line connection during power grid installation for station area identification and station line topology identification, but there may be power supply line connection during power grid installation The wrong situation leads to errors in the identification of the station a...
