Series Active Power Line Conditioner (SAPLC) is a custom power device which protects the sensitive loads against the voltage sags and swells. This paper presents three level diode clamped inverter with DC storage capacitors along with three single phase transformers as a SAPLC. Modifi ed scalar control strategy with fast response time is used to improve the performance of SAPLC. The simulation of the proposed model is carried out to verify the performance of SAPLC in conditions of balanced sag, balanced swell and unbalanced sag. Results are analyzed to check the effectiveness of the proposed model with selected control strategy.

Abstract


Series Active Power Line Conditioner (SAPLC) is a custom power device which protects the sensitive loads against the voltage sags and swells. This paper presents three level diode clamped inverter with DC storage capacitors along with three single phase transformers as a SAPLC. Modifi ed scalar control strategy with fast response time is used to improve the performance of SAPLC. The simulation of the proposed model is carried out to verify the performance of SAPLC in conditions of balanced sag, balanced swell and unbalanced sag. Results are analyzed to check the effectiveness of the proposed model with selected control strategy.
