Transformer area line loss refined analysis and management system

Abstract

The invention provides a transformer area line loss refined analysis and management system which comprises a transformer, a telegraph pole, a low-voltage line of the telegraph pole and a low-voltage user. Low-voltage detection devices are installed at an outgoing line end of the transformer, a branch point of the low-voltage line and a branch line of the low-voltage line. Each of the low-voltage detection devices comprises a voltage level selector, a multi-way switch selector, a voltage detection circuit, a comparator, a processor, a wireless transmission unit and the like. An output end of the voltage level selector is connected with an input end of the multi-way switch selector, an output end of the multi-way switch selector is connected with an input end of the voltage detection circuit, and the processor is connected with the wireless transmission unit. A first register and a second register are connected with the processor through a data bus; and the wireless transmission unit communicates with a power supply bureau server. By applying the system, the power consumption condition of a public transformer user can be monitored in real time, the user power consumption metered by amarketing system of a power supply bureau, the line loss of a metering area and the power consumption abnormality can be measured and processed quickly.

Description

technical field [0001] The invention relates to the technical field of electrical management devices, in particular to a fine analysis and management system for line loss in a station area. Background technique [0002] At present, there are low-voltage metering equipment in the power system. This kind of equipment is mainly composed of a low-voltage metering box, which is composed of a multi-functional meter and a metering box. Source of data for line loss analysis in utility substation area. [0003] However, according to the actual use on site, the use of this device for online loss analysis has the following problems: [0004] (1) At present, the multi-functional electric energy meter can only measure the user's electricity in the public transformer station area, and at the same time, it can be used as the source of line loss analysis data, but it can only calculate the comprehensive line loss of the station area, but not the regional line loss; [0005] (2) Due to the...

Problems solved by technology

[0004] (1) At present, the multi-functional electric energy meter can only measure the user's electricity in the public transformer station area, and at the same time, it can be used as the source of line loss analysis data, but it can only calculate the comprehensive line loss of the station area, but not the regional line loss;

[0005] (2) Due to the lack of effective maintenance of multi-functional electric energy meters due to years of operation, many meters are inaccurate and abnormal, and there is no effective means to monitor whether the meters are operating normally;

[0006] (3) The multi-functional electric energy meter has no effective function to check whether the power consumption of the public transformer user is abnormal, and whether there is electricity theft;

[0007] (4) At present, it is impossible to effectively judge the abnormal line loss caused by line aging, inaccurate measuring instruments, line overload, and electric leakage.
