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 can be implemented in various ways defined and covered below.

[0049] like figure 1 As shown, the first embodiment of the present invention provides a station area identification method, which identifies the station area power supply network based on the load jump identification technology, specifically including the following steps:

[0050] Step S1: Apply data collection to all sub-meters and master meters 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: Match the load jump curves of all sub-meters with the load steady-state value jump curves of the main meter, and obtain the attribution of the sub-meters with load jumps according to the matching results.

[0052] Among them, load jump is the digital abstraction of ...

Abstract

The invention discloses a station area identification method and a method for constructing station area line topology. The station area identification method and the method for constructing station area line topology of the present invention adopt the load jump identification technology, based on collecting the load value of each node in the station area power supply network, and forming the load jump curve of each node, by combining all The load jump curve of the sub-meter is matched with the load jump curve of the main meter to realize the judgment of the mounting relationship of the corresponding meter, realize the identification of the station area and construct the line topology of the station area, and can eliminate the influence of line loss power , increasing the recognition accuracy.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a method for identifying a station area, and also to a method for constructing a network topology in a station area. 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 identification method of the station area and the method of constructing the line topology of the station area are all based on the power supply line connection during the grid installation to carry out the station area identification and the line topology identification of the station area, but there may be power supply line connections during the grid installation In the event of an error, it wi...
