Abstract

The embodiment of the invention provides an electric energy quality testing method and system and a computer readable storage medium, and belongs to the field of electric power testing. The method comprises the following steps: acquiring system architecture data of process equipment of a to-be-tested enterprise power grid in a shutdown state and a normal operation state through an acquisition terminal, and selecting a plurality of test points to establish a database corresponding to the to-be-tested enterprise power grid at a cloud end; performing data test on the secondary side signals of the voltage transformers and the current transformers accessed to the plurality of test points by the acquisition terminals in combination with a database; and acquiring power quality data corresponding to the operation conditions of the process equipment corresponding to the plurality of test points in the outage state and the normal operation state, and comparing the power quality data with power quality index limit values of the plurality of test points in a database corresponding to the enterprise power grid to be tested to obtain a test result. According to the invention, the requirement of complex power quality problem analysis can be met, and the flexibility of power quality test is improved.
