Description

technical field [0001] The invention relates to the field of distribution network monitoring, in particular to a low-voltage distribution network stealing and leakage detection device, a monitoring system and a monitoring method. Background technique [0002] The State Grid Power Company reported that the hook-up electricity theft phenomenon in the station area is very serious, resulting in high line losses in the station area, damage to the economic benefits of the enterprise, and hook-up electricity theft happens from time to time. For a long time, the lack of effective technical means for monitoring and investigation has brought many troubles to power grid enterprises. [0003] Secondly, at present, line leakage is a sore point and difficulty that plagues the safe and economic operation of low-voltage agricultural distribution networks. Traditional leakage current investigation mainly relies on the experience of staff, which is time-consuming and laborious. It is difficul...

AI Technical Summary

Problems solved by technology

Problems: (1) Manual investigation is time-consuming and labor-intensive. It is difficult to find hidden and occasional electricity theft, and the operation and maintenance personnel are under great pressure; (2) Manual line inspection has poor real-time performance and cannot quickly and accurately locate the electricity theft point

Existing scheme 2: External equipment extracts data from electric energy meters and metering master stations. Problems: (1) Not allowed in principle: The International Organization for Legal Metrology (OIML) issued the IR46 standard in October 2012, and China is its member state , it is also necessary to adopt and implement the agency's IR-type international measurement regulations, which require that the measurement function of the electric energy meter is independent of other functions, and the legal measurement data should be protected

(2) The measurement data of the entire station area is huge, the algorithm is complex, the data update is slow, and the real-time performance is poor, so it cannot be processed in time

(3) Measurement data is strictly controlled and cannot be easily obtained

(4) Metering data security is threatened

[0006] The patent document with the patent number ZL201910708050.8 discloses an edge computing anti-stealing method and device based on the ubiquitous power Internet of Things, starting from the abnormality of the magnetic field, and then judging whether there is a behavior of stealing electricity, which requires detection and calculation The data is still very complex, the data update is slow, the real-time performance is poor, and it cannot be processed and positioned in time
