Abstract :
This paper focuses on distribution voltage control when over-voltage or under-voltage occurs in the low-voltage (LV) distribution line. The distribution voltage control is performed by transformer and ac-ac converter. Transformer supports a part of settled voltage and ac-ac converter controls voltage disturbance. Bi-directional ac-ac converter employs digital control using field programmable gate array (FPGA). This method enables simple and fast the distribution voltage control. In this paper, voltage control concept is explained. Scaled-down experimental result is shown, when load condition is changed.
