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

Abstract

The invention relates to a simulated fault smart meter for three-phase power supply, which has a built-in fault simulation operating program. Several error modules are preset in the fault simulation operating program. When the error module is run, the software fault corresponding to the error module is simulated. occurs; a fault simulation control device is also provided, the fault simulation control device is connected to the hardware module, and the fault simulation control device changes the wiring of the hardware module to cause a corresponding hardware fault to occur in the hardware module. and an electrical test simulation device based on the above-mentioned simulated fault smart meter. The invention can simulate power grid operation events, simulate typical faults of electric energy meters, simulate harmonic tests of the power grid and other faults. When an abnormal fault occurs in the electric energy meter field, the trainees can quickly and accurately handle the fault of the electric energy meter and issue a systematic and complete fault report, which can provide electric power companies and electric energy meter manufacturers in various network provinces with electric energy meter application development and technical research. It provides a lot of practical basis.

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...
