Abstract

The invention discloses a system and a method for monitoring a power utilization state. The system comprises a primary side three-phase current sampling unit, a secondary side sampling unit and an abnormal power utilization monitoring unit. The primary side three-phase current sampling unit comprises three sampling devices used for obtaining A-phase current, B-phase current and C-phase current respectively, wherein each sampling device comprises a primary side phase current sampling module used for acquiring phase current sampling data, and a main processing module used for networking by utilizing a micro-power wireless mode communication module, determining a main device and sending primary side three-phase current sampling data to the abnormal power utilization monitoring unit by utilizing the determined main device; the secondary side sampling unit is used for acquiring secondary side active power and secondary side reactive power of the target wire monitored at the metering point;and the abnormal power utilization monitoring unit is used for calculating a power relative error based on the primary side apparent power and the secondary side apparent power, and determining the power utilization state of the target wire according to the power relative error.

Description

technical field [0001] The present invention relates to the technical field of anti-stealing electricity analysis and monitoring, and more specifically, to a system and method for monitoring electricity consumption status. Background technique [0002] With the development of economy and society, the demand for electricity from various industries and residential users is increasing day by day. In order to seek personal gain, some users use various means to steal electricity and use electricity in violation of the contract, which disrupts the normal order of power supply and consumption and brings great harm to the safety of electricity consumption. threaten. The continuous expansion of the field of stealing electricity, strong concealment, gradual professional development of gangs, and rapid spread have put forward higher requirements for on-site electricity management. Lack of professional anti-stealing equipment, unable to accurately locate power-stealing users, unable to...
