Electric power metrological supervision system and supervision method

Abstract

The invention provides a power measuring and monitoring system and monitoring method, comprising a power measuring device for measuring the power of the first side and the second side of the transformer and a mainframe for measuring and monitoring used for storing a threshold and calculating the relative difference of the energy data of the two sides of the transformer, when the relative difference is greater than the threshold, the alarm information is generated and the communication module sends the alarm information. The method comprises: mounting the power measuring device and mainframe for measuring and monitoring on the transformer to respectively calculating the power of the two sides of the transformer; storing a threshold on the mainframe and calculating the relative difference of the energy data of the two sides of the transformer, if the relative difference is judged to be greater than the threshold by the mainframe, the monitoring center sends an alarm information. The invention can effectively monitor the behavior of electric larceny and reduce the cost of the monitoring center.

Description

technical field [0001] The present invention relates to a device for measuring electric energy, in particular to an electric power measurement supervision system and a method for supervising electric power measurement by using the system. Background technique [0002] At present, the theft of electric energy is very rampant. Electricity thieves adopt various methods to not calculate or reduce the amount of electricity in order to achieve the purpose of not paying or paying less electricity bills, causing heavy losses to the country. In order to prevent the theft of electric energy, the electric power department dispatches inspectors to inspect the power supply lines on a regular or irregular basis, but the inspection time is poor and the inspection is not in place. Evidence is more difficult to obtain. [0003] Therefore, the invention patent application with the publication number CN1866033A discloses an invention called "real-time monitoring system for preventing electric...

Problems solved by technology

[0006] However, the anti-stealing device is not a device fixedly installed on the transformer. When using the anti-stealing device, it needs to be connected to the transformer, which brings inconvenience to use.

At the same time, since the anti-stealing device cannot monitor the power consumption of the transformer in real time, inspectors are still required to detect the power consumption on the spot when using it

Moreover, the use of the anti-stealing device also requires a large monitoring center to monitor the power data of the high-voltage side and low-voltage side of the transformer, which makes the cost of the monitoring center high
