With the rapid increase of the large-scale equipment in the development of the metallurgical industry, the power load brings complex harmonic current, whose reactive power and load changes surge drastically, there are fluctuations and flickers on the high-voltage power supply system＇s bus voltage. Therefore, it＇s urgent to improve power system＇s stability and the voltage quality. After analyzing the hazards of harmonic and the superiority of SVC, the article describes the design of SVC harmonic suppression system, routine tests, line check, monomer debugging, and the interaction with a load and without a load, the system achieves the expected effect.
