Abstract

This paper describes the structure and functionalities of a unified power quality conditioner (UPQC) built in Simulink. The UPQC-model consists of a series transformer with a series inverter, connected back to back to a shunt inverter via a dc link capacitor. In the presented model, the UPQC is installed in the middle of a low voltage line, where several loads can be activated to cause power quality disturbances defined by DIN EN 50160, e.g. unbalance, harmonics or rapid voltage changes. The current and voltage control schemes in dq system are explained and the efficacy of the UPQC is shown for several load cases. The complete model is published on Github.com.
