Static series compensator for voltage dips mitigation

Power quality problems encompass a wide range of disturbances, which cause costly loss of production to critical processes. Voltage dips are the major source of power quality-related problems. The static series compensator (SSC), commercially known as dynamic voltage restorer (DVR), is best suited to protect sensitive loads against such incoming supply disturbances. This paper presents an overview of configuration, design criteria, and rated power estimation of the SSC. The used control techniques are discussed aiming to compromise among them based on their suitability with the SSC requirements.
