Abstract

The invention relates to an electric energy quality data representation method comprising steps of: establishing interconnection with an electric energy quality monitoring system and acquiring electric energy quality data; encoding the electric energy quality data in a tetrad format and acquiring target electric energy quality data with a unified format standard and uploading the electric energy quality data to a master station; and reading the target electric energy quality data and fast recognizing electric energy quality monitoring system information. The method satisfies demands for real-time analysis and post hoc analysis, provides scientific decision basis for electric energy quality treatment, enhances power grid security and reliability, and may satisfy a time representing method enabling large-grained stable data to be consistent high-precision sampling values to solve inconsistent time reference.

Description

technical field [0001] The invention belongs to the field of electric power engineering, and in particular relates to a method for expressing power quality data. Background technique [0002] With the development of the power quality monitoring system, the scale of monitoring points continues to expand, and the application requirements for monitoring data continue to change. The original power quality data formats used for computer storage and data exchange, such as PQDIF and COMTRADE, can no longer meet business needs in the following aspects : [0003] 1) The measurement process cannot be expressed completely and consistently. Many power quality indicators are obtained through multiple calculations. There are many choices in the calculation process, such as hardware sampling methods and cumulative calculation methods. In existing data formats, these metadata used to describe the measurement process cannot be directly represented in the data, or are scattered in multiple l...
