Power user onsite electric energy meter fault remote determination method

Abstract

The invention discloses a power user onsite electric energy meter fault remote determination method. A local electric energy meter monitoring terminal is arranged at each factory site, an automatic remote processing unit, a data server and an electric energy meter management monitoring terminal which are connected through a local area network are arranged at a far-end management master station, the local electric energy meter monitoring terminals are connected with electric energy meters of power consumption sites under the jurisdiction of the factory sites where the local electric energy meter monitoring terminal are disposed through downlink communication cables, the local electric energy meter monitoring terminals monitor metering conditions and operation conditions of the electric energy meters connected therewith in real time and send the metering conditions and the operation conditions of the electric energy meters to the data server disposed at the far-end management master station through an uplink remote communication network, and the automatic remote processing unit performs automatic remote processing on fault local electric energy meter monitoring terminals capable of normal communication, such that online real-time unified management of the electric energy meters is realized.

Description

technical field [0001] The invention relates to the field of electric power systems, in particular to a method for remotely judging faults of on-site electric energy meters of electric power users. Background technique [0002] The currently used energy meter testing equipment has many functions and rich display content, but generally it can only be tested locally at the energy meter production plant, and it is the testing equipment for the energy meter before it leaves the factory. As for the electric energy meter that has been installed and used at the user end, it is necessary to test it. Currently, an on-site calibrator is used, that is, a local testing device. For the electric energy metering device that has been installed and put into operation, there is currently no equipment that can perform all-round online testing on it. The maintenance of the electric energy meter is still in the process of failure, repair, on-site inspection, repair or replacement. stage, time-c...

Problems solved by technology

For the electric energy metering device that has been installed and put into operation, there is currently no equipment that can perform all-round online testing on it. The maintenance of the electric energy meter is still in the process of failure, repair, on-site inspection, repair or replacement. stage, time-consuming and labor-intensive, unable to conduct unified online management and data analysis of electric energy meters, which greatly affects the management and maintenance of electric energy meters

In addition, due to the extremely large number of users, according to the existing workflow for faulty equipment, personnel are dispatched directly through the system and then arranged for on-site processing, which brings a huge workload for on-site maintenance.
