This invention provides a method, device, and system for intelligent power quality sensing, relating to the field of power distribution network technology. The intelligent power quality sensing method provided by this invention calculates power quality data for the line under test using power data collected from the line under test. This power quality data serves as the basis for predicting the changing trends of power data. An intelligent sensing strategy is then employed to manage pre-deployed power quality monitoring micro-applications, thereby adjusting the monitoring frequency and range of the power data for the line under test. This allows for dynamic adjustment of the monitoring granularity of power quality monitoring based on dynamic changes in the power grid, thus ensuring accurate collection of power quality information.
