Southern grids, although it can still be used as an embedded power flow device to help control power flow within the AC system. The stations could potentially be shifted to elsewhere to export/import power from other countries. Sometimes the excess power fed to the southern grid by this HVDC link is flowing back to
Western region through the 765 kV AC lines between Southern grid and the Western grid with futility.
253:. The close proximity of the two converter stations meant that the control systems needed to be carefully coordinated, a task made more challenging by the fact that the two stations were built by different manufacturers. To address this problem a series of joint simulation studies, involving the control equipment from both converter stations connected to a common simulator, was performed.

On 31 December 2013, the
Northern, Eastern and Western grids were synchronised with the Southern regional grid, creating a single synchronous AC grid over the whole of India. As a result, the converter station is no longer required for its original purpose of asynchronously linking the Western and
301:(12 at each end of each pole) and with each thyristor valve including 54 thyristor levels in series. The thyristors are of 100 mm diameter and are rated at 5.2 kV. The thyristor valves are floor-mounted even though the station is located in a seismically active area.

Southern side there are also two, 50 MVAr shunt reactors.
