Modern society is the era of knowledge economy with information technology as the guide. In the past, many electrical equipment in the power system could work normally within the relatively large variation range of rated parameters. However, in the past decade, the development of information technology has led to the extensive use of computer-based, microprocessor-controlled electrical equipment and power electronic equipment in power supply and distribution system. Such equipment is more sensitive to grid fluctuations, so it also puts forward higher requirements for power quality.

Nowadays, industries that need to improve power quality include large industrial enterprises (automobile, steel, nonferrous metals, metallurgy, petroleum, electric power, etc.); new energy access (photovoltaic, wind power, energy storage, charging station, etc.); Data Center (Internet data center, financial data center); intelligent buildings (CBD, office buildings); rail transit (subway, maglev); large medical facilities Large scale aviation facilities; warehousing and logistics; port shore power; laboratory / laboratory, etc.

We focus on the discovery and management of power quality problems, detect and analyze the load characteristics of power quality for major enterprises, find out the weak points of power quality, and put forward professional solutions for abnormal power quality problems.
