Design of a Measurement System for Characteristic Parameters of Earthing Devices in Ultra-high Voltage Electromagnetic Environments
To ensure safe and stable operation of ultra-high voltage power grids,it is of great significance to study the characteristic parameter measurement system of earthing devices under ultra-high voltage strong electromagnetic environ-ment.Focusing on the aforementioned topic,the present work made a preliminary attempt to design a measurement sys-tem based on virtual instrument technology,whose principles,hardware type selection,and software design are outlined and clarified in this paper,with an emphasis on the measuring algorithm and strong power frequency interference filtering method.The proposed measurement system was verified by simulative experiment to be effective and accurate.
