Concentrated monitoring method and device for resident household power utilization conditions

Abstract

The invention discloses a concentrated monitoring method and device for resident household power utilization conditions and belongs to the field of power utilization monitoring. A lead is led out of azero line of a front master switch incoming end of a certain resident household in a joint household electricity meter box to a concentrator; a signal line is led out of a fire line of a front masterswitch outgoing end of each resident household to the concentrator, so that power supply voltage in each resident household is obtained; if the power supply voltage exceeds a preset fixed value, theconcentrator uploads resident household numbers and excess values to a monitoring terminal through a wireless transmission module or a carrier wave transmission module; if the power supply voltage ofthe lower end of the front master switch of certain resident household is zero and the power supply voltage of other resident households is normal, the front master switch of the resident household isregarded to be in a trip state. The power supply condition and the leakage current value of each resident household can be monitored on the premise that existing configuration of the user is unchanged; the last mile bottleneck of intelligence of power distribution networks is broken through, and monitoring of the power utilization condition of the resident households is realized in a real sense.

Description

technical field [0001] The invention belongs to the field of electricity consumption monitoring, and in particular relates to a monitoring method and a monitoring device for indoor electricity consumption of residents. Background technique [0002] The smart distribution network requires real-time monitoring or monitoring of the electricity consumption of households in the power supply area of ​​the transformer (referred to as the station area). Since the electricity consumption of residential households affects the power supply status of the distribution network in the station area, it is not only related to the daily life of residents, but also related to the operation and maintenance management of the power supply department. It is very important to monitor the power supply status, power quality and leakage current. [0003] At present, the large platform monitoring center of the power company at the provincial level has monitored the power parameters in the power distri...

AI Technical Summary

Problems solved by technology

On the one hand, this technical solution still cannot directly obtain the quality of the power supply voltage in each residential user and whether the main switch of the incoming line of the user is in the "closed" state, and cannot really realize the supervision of the electricity consumption of the residential households; on the other hand, its The monitoring cost is high, and the installation and maintenance workload is heavy, which invisibly increases the renovation cost and daily maintenance cost for each resident user, which is not easy to be accepted by ordinary resident users
