High Voltage Direct Current systems have been used for
transporting electrical energy for very long distances, at high
voltages (100- 1000 kv). On utilize thyristorized or transistorized
power converters, one converter is working as rectifier at s
ending
side, and the other is working as inverter at receiving side. Back to
Back Converters are used also where the rectifier and inverter are at
the same station, transmission line has hundreds of meters as long.
In our model we used non controlled three phase rectifier as
sending station and controlled three phase bridge as receiving
station (Graitze).
