【Abstract】 Being the most active technology and having a great feature in the field of reactive compensation now,SVC(Static VAR Compensator)is increasingly noticed and being made wild application.With the development of electronic technology and computer control technology,various kinds of automatic and quick reactive compensation devices have come into being in succession,which greatly advances the development of SVC compensation technology.In this article,the author briefly analyzes the impact voltage fluctuation,harmonic wave and voltage flicker caused by the load of large rolling mill powered by thyristor and the similar loads. introduces the existing problems of traditional compensation devices,and expounds in detail the characteristics,classification and functions of SVC and the problems needing attention in engineering design and applying.更多还原
