PROJECT TITLE :

Matrix Converter Based Active Distribution Transformer - 2016

ABSTRACT:

This paper proposes a matrix converter-based mostly active distribution transformer (MC-ADT) with enhanced management functionalities to be utilized in smart grids (SG). The proposed MC-ADT uses a matrix converter (MC) connected to a transformer inserted in series with the grid, and permits: one) real-time voltage regulation of the low-voltage aspect of the MC-ADT, based on an adjustable reference value outlined by the SG needs and bounded by the standard values; 2) capability to control the LV grid voltage even in case of sags, voltage rises, and overvoltages in the transformer medium-voltage side; and three) contribution to power factor correction in the MV facet. The MC-ADT grid voltage regulators are synthesized, establishing the MC reference currents. To guarantee the tracking of the MC input and output reference currents, the area vector illustration, along with sliding-mode direct management techniques, are used. The obtained experimental and simulation results show that the proposed system is in a position to manage the LV grid voltages even for sags and overvoltages up to twentypercent in the MV side, and contributes to power factor correction in MV, whereas presenting fast dynamic response, without overshoot and almost zero steady-state error.
