Shunt reactive compensation for voltage dip and unbalance

Welgemoed F. ; Beukes J. (2010)

Conference Paper

Voltage dips, swells and unbalance are phenomena that deteriorate power quality. These can be successfully compensated for by means of shunt reactive compensation. Implementing power electronic converters make dynamic compensation possible. The design of the controllers for voltage dip and unbalance compensation is discussed. Some of the key procedures discussed include system modeling, controller design, sequence decomposition and controller implementation issues. The designed controllers are implemented, evaluated and the results shown.
