With the development of modern science and technology, power electronics technology is widely used. Electric energy still plays an essential role in human production and life, and there are many factors that affect power quality. Factors such as high order harmonics, voltage fluctuations, flicker, imbalance, equipment errors, communication interference, etc. not only reduce the power supply and consumption equipment, but also threaten the operation of the entire power system.Power quality monitoring屏Functional features:

1. Data collection and analysis: The power quality monitoring screen monitors power quality in real-time, such as voltage, current, voltage fluctuations, flicker, harmonic current, and other parameters, and transmits them to the monitoring center in real-time. Based on different power quality indicators, corresponding statistical analysis is carried out and various reports are automatically generated.

2. Visualization screen of monitoring center: Real time display of relevant data of monitoring points, and remote commands can be issued to on-site monitoring instruments and other equipment for remote communication control and parameter setting and modification.

3. Identification and regional positioning of harmonic interference sources: Based on monitoring data, establish a data analysis system to identify and locate harmonic interference sources, and further provide relevant information for power quality management. And provide suggestions for solving power quality issues.

4. Automatic storage: Collect power quality data for future comprehensive queries.

5. PC and APP: corresponding PC and mobile apps can be provided according to user needs, enabling important data to be viewed and managed anytime, anywhere.

The power quality monitoring screen can be applied to substations and power plants of various voltage levels, as well as various industrial and mining enterprises, electrified railways, urban subways, and other large electricity users. I believe that with the continuous deepening and widespread application of power technology, it will become an inevitable choice for the construction of power grid user side distribution systems in the future.
