Simulated fault smart meter and electrical test simulation device for three-phase power supply

Abstract

The present invention relates to a failure simulation smart electric meter for a three-phase supply. The failure simulation smart electric meter is internally provided with a fault simulation running program, a plurality of fault modules are preset in the fault simulation running program, and when the fault modules are run, software faults corresponding to the fault modules are simulated to occur. The failure simulation smart electric meter is also provided with a fault simulation control device, and the fault simulation control device is connected with a hardware module and changes wiring of the hardware module to enable corresponding hardware faults of the hardware module to occur. An electrical test simulator based on the above failure simulation smart electric meter is also provided. The failure simulation smart electric meter can simulate and realize power grid operation incidents, and simulates electric meter typical faults and power grid harmonic tests and the like. When the electric meter fails on site, learners can rapidly and accurately handle the faults of the electric meter and provide systematic and complete fault reports, thereby providing vast practical evidences on electric meter application extension and technical researches for provincial electric power companies and electric meter manufacturers.

Description

technical field [0001] The present invention relates to the technical field of teaching and testing systems, and more specifically, to a fault-simulating intelligent electric meter for three-phase power supply, and an electrical test simulation device based on the above-mentioned fault-simulating intelligent electric meter. Background technique [0002] With the construction of smart grid, single-phase and three-phase smart energy meters have been widely used in power metering, but many problems have been found in the process of use, and the faulty meters found on site can be directly replaced by the meter manufacturer. , Due to the limitation of the technical level of the on-site meter installation electrician and operation and maintenance personnel, it is impossible to make a complete and systematic fault report on the fault of the electric energy meter. Do in-depth research. Contents of the invention [0003] The purpose of the present invention is to overcome the defi...
