An intelligent line loss analysis device in the station area

Abstract

The invention discloses an intelligent line loss analysis device for a station area. The device includes: a metering unit for real-time monitoring of the metering data of branch lines in the station area and sending it to the line loss analysis unit; an automatic meter reading unit for real-time reading Read the measurement data of the user meter box and send it to the line loss analysis unit; the topology identification unit is used to obtain the topology identification signal for identifying the station area and branch lines, and send it to the line loss analysis unit; the line loss analysis unit is used for the receiving station The metering data of the branch lines in the district or the metering data of each household meter in the user meter box and the received topology identification signal, compare the received metering data according to the topology identification signal, and obtain the metering data of the branch line or line loss user meter box in the station area Line loss output. The invention has the advantages of simple structure, low cost, intelligent analysis of line loss in the station area, high analysis precision, and quick fault location.

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
