Abstract

The invention relates to the electric energy quality monitoring apparatus self-test technology field and the invention is an electric energy quality monitoring apparatus self-test apparatus and a self-test method thereof, wherein the electric energy quality monitoring apparatus self-test apparatus comprises a standard source, an electric energy quality monitoring apparatus, a switch and a test terminal; the standard source and the electric energy monitoring apparatus are connected through a test cable; the switch is connected with the test terminal, the standard source, and the electric energy monitoring apparatus through network cables; and the test terminal comprises an automatic test layer and an apparatus test side editing layer. According to the invention, the self-test apparatus can realize closed loop automatic test; after the test is finished, a test report with a standard format is automatically formed, so that the phenomena of lacking items and missing items due to human factors in the test are prevented; the potential safety risk due to incomplete test of the apparatus is lowered; the normal, standard and efficient automatic test is realized; and the purposes of lowering the requirements to worker, simplifying the working processes and normalizing the data format are realized.

Description

technical field [0001] The invention relates to the technical field of self-testing of a power quality monitoring device, and relates to a self-testing device for a power quality monitoring device and a self-testing method thereof. Background technique [0002] With the rapid development of my country's smart grid, the degree of automation is gradually increasing, and a large number of sensitive equipment and nonlinear power electronic equipment have been put into use in large quantities. The monitoring requirements for power quality such as voltage deviation, current deviation, frequency deviation, voltage fluctuation and flicker, and harmonics Therefore, many high-precision power quality monitoring devices are required to be applied in the field of power quality monitoring, and power quality monitoring devices also need to be tested regularly. At present, power quality detection devices have not yet formed a standardized test process. The test process It also cannot realize ...
