Abstract

Quality control issues that can cause complex stack hardware to fail operation resulting in voltage drop occurring. A short circuit to the ground in the conveyance control frame is the cause of the failure. To overcome this failure, the elective arrangement of the stack safeguard against the voltage registers with electronic control based on a device that provides a three-phase voltage source can be controlled, namely a dynamic voltage restorer (DVR). This research focuses on pre-sag based of DVR execution with a discovery framework placed on the input side of the control supply. The DVR incorporates the voltage difference between the annoying droop and pre-fault state. The effect of a two-phase short circuit to ground fault with four different transformer winding arrangements was carried out using Matlab/Simulink. The simulation results show that various distribution transformer arrangements will produce various voltage drop effects. Phase shift and maintain stack voltage between 0.9-1.1 pu of real voltage to compensate for voltage-sag.
