In this paper, an AC-DC-AC three-phase transmission system that employs two six-switch inverters is studied. The inverters are connected by an inductive DC link, and are controlled in order to ensure a high power factor at the source side, a regulated voltage at the DC side and low-distorted currents at the load side. The inverters are modeled in the average regime in order to design suitable regulators...
The energy supply systems of telecommunications power stations are based on rectifier units of high power factor, compact with high efficiency. To obtain high power factor it is necessary to use in the ac-to-dc conversion stage a power factor pre-regulator, which leads to an increase of the input voltage levels of the dc-to-dc stage. In order to reduce the voltage efforts over the switches of the...
This paper presents a method to maximize the power generated from a 3-turbine wind farm, and supply it to the grid with high power quality. Different control methods are applied to each subsystem; generation, aggregation, and finally grid connection. The control goal in the generation subsystem is to extract maximum wind power below rated wind speed, and to limit the power above rated wind speed....
