Intelligent anti-electricity-stealing system

Abstract

The invention provides an intelligent anti-electricity-stealing system comprising an electric parameter sensor, a metering module, a main metering meter, a TTU, and a data center. The electric parameter sensor is used for collecting secondary side current data and transmitting the data to the metering module wirelessly or through a PLC module. The metering module is used for converting the data into active power and sending the active power as practically measured power to the TTU. The main metering meter is used for metering power consumed by the user; and the TTU reads the power of the metering meter. The TTU is used for sending the stored power and meter power to the data center, comparing the practically measured power with the meter power regularly, and sending a warning signal to thedata center when the difference exceeds a preset threshold. The data center is used for storing the practically measured power and the meter power and determining whether the user steals electricityafter receiving the warning signal. Therefore, the defect of lack of the secondary installation and maintenance is overcome; the possibility of cross-meter electricity stealing is eliminated fundamentally; the electricity stealing behavior is prevented timely by combining the comprehensive record of power abnormity; and the accurate data are provided for the follow-up inspection and payment.

Description

technical field [0001] The invention relates to the field of electric power, in particular to an intelligent anti-theft electricity system. Background technique [0002] Driven by interests, electricity theft, especially by large users, is very common, endangering the security of the power grid and bringing huge economic losses to the country. There are various means of stealing electricity, and there are also various anti-stealing technologies, but most of them are solutions for one or more methods of stealing electricity, and there are anti-theft dead zones or cannot adapt to new electricity stealing technologies. [0003] At present, the domestic operation is relatively good, through the installation of wireless current transformers on the primary side of the power transformer, combined with the power service terminal, and through the comparison of the primary and secondary side currents, the electricity theft behavior is effectively supervised and obtained. It has achie...

Problems solved by technology

The key technology of this scheme is to install a radio parameter collector on the high-voltage side. The main disadvantages are: (1) secondary construction is required, and installation and maintenance are difficult due to the operation on the high-voltage side; (2) the primary and secondary current of the transformer The comparison of the transformer is superimposed on the loss of the transformer, and the parameters need to be adjusted; (3) the wireless module uses induction to take power, and the low current cannot work, and the error is large, and the accuracy of the result needs to be improved
