Feasibility of thyristor controlled series capacitor for distribution substation enhancements

A new approach for voltage profile enhancement in distribution power systems using fixed and thyristor controlled series capacitor (TCSC)

“…Therefore, finding a solution to keep the voltage level in accordance with standards becomes imperative. To achieve this aim, optimal strategy for reactive power compensation and voltage improvement must be used [3]. To enhance the voltage and to control the reactive power, there are different voltages controlling devices such as tap changing transformers, voltage regulators, shunt/series capacitor banks, etc.…”

“…The series compensation is controlled by the capacitors switching on and off, while the current limitation and interruption is achieved by the insertion of a resonant LC circuit in the transmission line. Godart et a1 [3] conducted a study about the feasibility of TCSC for distribution substations enhancement taking into consideration load expansion. Moschakis [6] proposed TCSC as voltage profile enhancement compensator in distribution radial feeders.…”
