Embodiment Construction

[0028] Specific embodiments of the present invention are further explained below.

[0029] There is a definite electrical connection between the station area transformer and the user's ammeter, and the line voltage drop can be ignored within the station area power supply radius, so the voltage on the user side will definitely increase with the increase of the station area outlet voltage. They have a high degree of correlation, and the trend of change is highly consistent. For example, if the transformer is manually shut down, the household meter that is subsequently powered off must belong to the substation power supply of the station; on the contrary, if the transformer is manually put into operation, the household meter that is then powered on can be reconfirmed to belong to the substation power supply of the station. However, this method is a huge time-consuming and labor-intensive project, which not only brings a lot of losses to the power company, but also may lead to civ...

Abstract

The invention discloses a court topology identification method. The method comprises: voltage fluctuation of a low-voltage side of a court transformer is made; a voltage of the low-voltage side of thecourt transformer and voltages of to-be-identified user ammeters are collected respectively to obtain a corresponding reference number sequence and a corresponding comparison number sequence; and a gray correlation analysis is carried out to determine a court topology and the like. The court topological identification method has the following beneficial effects: problems that lots of manpower andmaterials are consumed by using a court communication instrument and court crossing caused by using a carrier technology are solved; the court topology identification becomes accurate and convenient;and compared with the data analysis methods like the regression analysis and primary cost analysis of mathematical statistics, the gray correlation analysis method needs a few of samples and does notrequire that the samples conform to a typical distribution law and the computing load is reduced.

Description

technical field [0001] The invention relates to the technical field of power grid topology data management, in particular to a method for identifying the topology of a station area. Background technique [0002] The transformer in the station area is the last transformer through which electric energy reaches the user. It not only undertakes the energy conversion task of converting high-voltage power into low-voltage mains power, but also undertakes the collection of power consumption information of users within its power supply range by its subsidiary concentrator equipment. The task is a dual hub of energy and information. [0003] However, with the continuous increase of electricity load leading to the changes and adjustments of power facilities (such as relocation, expansion, cutover, distribution, etc.), the power grid company will be affected by various technical reasons, irregular management or authority over the years of operation. Responsibility adjustments caused t...
