Intelligent line loss analysis device for transformer area

Abstract

The invention discloses an intelligent line loss analysis device for a transformer area, and the device comprises a metering unit which is used for monitoring the metering data of a branch line of thetransformer area in real time, and sending the metering data to a line loss analysis unit; an automatic meter reading unit which is used for reading the metering data of the user metering box in realtime and sending the metering data to the line loss analysis unit; a topology identification unit which is used for acquiring a topology identification signal for identifying the transformer area andthe branch lines and sending the topology identification signal to the line loss analysis unit; and the line loss analysis unit which is used for receiving the metering data of the branch lines of the transformer area or the metering data of each household meter in the user meter box and receiving the topology identification signal, and comparing the received metering data according to the topology identification signal to obtain the line loss output of the branch lines of the transformer area or the line loss user meter box. The method has the advantages of being simple in structure, low incost, capable of achieving intelligent analysis of the line loss of the transformer area, high in analysis precision, convenient for rapid fault positioning and the like.

Description

technical field [0001] The invention relates to the technical field of low-voltage distribution networks, in particular to an intelligent line loss analysis device for station areas. Background technique [0002] During the power transmission process, electric energy may cause a part of electric energy loss, that is, line loss, and the line loss rate is an important performance parameter to evaluate the performance of the power system. The abnormal line loss may also be caused by the wrong relationship between the household transformer, the fault of the metering device, or the existence of electricity theft by users. And so on, the relationship between households is changed into confusion, and it often happens that electricity is actually being used on site, but the system has not yet entered user information for meter reading, resulting in different periods of billing electricity in the total sub-meter, resulting in abnormal line loss rates in the station area; and the mete...

Problems solved by technology

However, this type of method can only roughly determine the line loss of the entire station area, and cannot determine whether there are problems such as the above-mentioned household transformer relationship error, metering device failure, or user power theft. , The lines are complex, there are many branches in the distribution transformer area, and the range of power supply users is wide. Once an abnormal line loss area is found, it is impossible to locate the faulty line and fault point of the specific line loss in the area. Troubleshooting areas, and power theft is usually scattered, making it difficult to troubleshoot fault points
