Abstract: The development of new energy grid brings opportunities and challenges to power quality to a certain extent. As more and more sensitive loads, power quality problems will become more and more prominent, will demand a large number of power quality governance products. As the power quality is not up to standard, the harm caused by electrical equipment will be more obvious, and to a certain extent, it will affect the safety of production and economic benefits of industrial enterprises. The improvement of power quality is of great significance to the safety, reliability and efficiency of the power grid, and is conducive to the development of the whole society. Therefore, in the construction of smart and new type power grid, it is necessary to pay more attention to power quality problems, improve the formulation of power quality standards, strengthen the research of power quality monitoring and analysis methods, and strive to establish a high efficiency, safe, reliable and environmentally-friendly power grid.
