Abstract

This paper studies static synchronous compensator (STATCOM) accessed in the system via intermediate taps on transformer high voltage wingdings. For Dyn11 type transformers, the proposed circuit configuration of DT-STATCOM is analyzed, and the function of reactive power compensation is verified. Then, the Euler-Lagrangian (EL) model of a distribution transformer-static synchronous compensator (DT-STATCOM) is established. This paper also proposes an improved ip-iq current detection method. Meanwhile, the passivity-based control (PBC) law which can decouple active and reactive power is proved. By selecting proper injecting damping, we can optimize the dynamic performance and realize fast compensation of reactive power. Finally, simulation results show the effectiveness of the proposed structure with PBC in reactive power compensation.
