Non-intrusive user power consumption fault identification method and system thereof

Abstract

The invention relates to a non-intrusive user power consumption fault identification method and a system thereof. The non-intrusive user power consumption fault identification method includes following steps: S1, acquiring data of the voltage, current and leakage current of a power inlet position of a user; S2, adding time stamps to the obtained data, transmitting the data to a cloud, and storingthe data in a database of the cloud; S3, analyzing the data in the database, obtaining an electric equipment behavior sequence of the user through identification, and monitoring change conditions of the main current and the leakage current; and S4, when it is monitored that a certain electrical characteristic quantity is abnormal, through event analysis, associating an abnormal condition with an electric appliance event, and determining the type of the electric appliance causing an electrical fault. According to the method and the system thereof, equipment installation can be completed by employing a non-intrusive method without power failure through measurement of the household total current and the household voltage monitoring power consumption conditions, the method is more convenient and fast, the troubleshooting time is saved, and the troubleshooting efficiency is improved.

Description

technical field [0001] The invention relates to the field of fault identification of user electricity consumption, and more specifically refers to a non-invasive user electricity fault identification method and system thereof. Background technique [0002] Existing user power consumption systems can actively cut off electrical connections when electrical faults such as short circuits occur, avoiding the expansion of faults and prompting the occurrence of faults. Current to judge whether there are electrical faults such as overcurrent, overload, leakage, etc. in the user's electrical circuit; the information that this method of fault discrimination can provide only stays on whether the fault occurs, and it is generally difficult to provide effective support in the follow-up troubleshooting . [0003] The equipment used to identify faults in traditional consumer power systems mainly includes air switches and leakage protectors. The air switch automatically disconnects when t...

Problems solved by technology

[0004] The traditional fault identification is a passive defense method, its main function is to cut off the electrical line connection when a fault occurs, and remind the user of the type of fault in the system; because of the lack of active identification, the fault information that the traditional method can provide is often At the system level, when users know that there is a fault in the power system, they still need to know the faulty electrical appliance through purely manual investigation. In addition, because it is a passive defense type, it is impossible to troubleshoot some hidden dangers, which has not yet been achieved. Electrical equipment with a fault threshold, unable to achieve fault prevention
