The power quality problems in power system are mainly divided into steady-state power quality problems and transient power quality problems. The former is characterized by waveform deformation, while the latter is characterized by frequency spectrum and transient duration. According to these two kinds of power quality problems, power quality monitoring technology came into being.

The realization of data sharing is the basic guarantee for the networking and intellectualization of power quality monitoring system. From a macro point of view, in order to provide users with high-quality power and ensure the safety of users, it needs the efforts of many parties. The power sector needs to make a set of scientific, reasonable and practical power quality standard system, which needs to be based on the power quality of users Different requirements to set different quality standards, so as to carry out hierarchical control, which is conducive to improve the power monitoring technology, achieve economic benefits, improve the production efficiency of the power sector, the standardization of power quality monitoring technology, help technical personnel exchange experience with each other, improve the work efficiency and quality of power quality monitoring, and correct the violations in the monitoring work It can be seen that the standardization of power quality monitoring technology is an inevitable trend.

With the gradual expansion of China's power grid scale, power quality monitoring points are also gradually increasing. In the process of development, power quality monitoring will gradually break through the limitations of monitoring points, realize the power quality monitoring of the same power supply system in different regions, and also may carry out comprehensive monitoring of different power supply systems. All of these are possible to be realized in the future with the support of computer network technology. Power quality monitoring will gradually realize intelligent. In addition to the basic function of displaying data, it will also have the functions of analyzing data, processing data and making decision analysis. For example, it can predict the faults that may appear in the later work process, start to identify the faults existing in the electric energy, identify the infection signals, and effectively control the power quality in real time. With the rapid development of electronic technology and network information technology, it is possible to realize intelligent power quality monitoring.
