Power quality management - Part 101: Power quality data application

Scope

IEC TR 63222-101:2025 aims to provide guidelines for power quality data applications on different aspects in public power supply systems at voltage ranges from LV, MV and HV with 50 Hz or 60 Hz rated frequency. It intends to provide a methodology for mining hidden knowledge and support power quality management based on PQ data analytics. Its primary goal is to serve different aspects of power system to promote the system maintaining its normal state and improve efficiency. It can also help avoid unexpected system events, equipment malfunction/maloperation, and production process interruption. The various methodologies and methods mentioned in this document are optional.
