چکیده

Shunt Flexible AC Transmission System (FACTS) device such as SVC and STATCOM, when placed at the midpoint of a long transmission line, play an important role in controlling the reactive power flow to the power network and hence both the system voltage fluctuations and transient stability. The validity of the mid-point location of these FACTS devices is investigated, when the actual model of the line is considered. This paper deals with the effects of considering the actual line model on the power transfer capability and stability when the shunt FACTS device is connected to the line. An attempt was made to determine the optimal positioning for placing the FACTS device in case of a 5-bus system to evaluate voltage stability and power flow angle characteristics for both the simplified and actual model.

A Comparison between SVC and STATCOM in Flicker Mitigation of Electric Arc Furnace using Practical Recorded Data

Electric arc furnace (EAF) is one of the largest loads in electric power systems. It is highly time varying and nonlinear. Its reactive power variations cause voltage fluctuations in nearby system which is known as flicker. On the other hand the nonlinear voltage-current characteristic causes strong voltage and current harmonics in EAF. To this end Flexible AC Transmission Systems (FACTS) techn...
