Abstract :
The distributed power flow controller (DPFC) based-on emitter turn-off (ETO) light converter is one newly proposed solid state power electronics technology based flexible AC transmission system (FACTS) devices which is effective to control the active power flow through the transmission lines. This modular DPFC has low cost, high reliability and makes it possible to have the transformerless connection to the existing power grid. In this paper, the development and analysis of modeling techniques and feedback schemes based on per phase control of DPFC are proposed. The simulation results and experimental results show the consistency of the propose model and the feasibility of the feedback control design for the DPFC per-phase operation.
