|ABB wins 600 MW HVDC order to reinforce Japanese power supply through HVDC JV with Hitachi|
In this project, the system to be delivered uses Voltage Source Converter (VSC) High-Voltage Direct Current Transmission (HVDC) power transmission technology, enabling interconnection between systems, with different frequencies implemented by converting alternate current into direct current. Hitachi will construct the system using an AC/DC converter, including the combination of an ABB Control and Protection System and a Hitachi converter transformer, based on the strategic partnership with ABB.
HVDC (high-voltage direct current) is a highly efficient alternative to alternating current (AC) for transmitting large amounts of electricity with higher efficiency and lower electrical losses. HVDC enables a secure and stable interconnection of power networks that operate on different voltages and frequencies (asynchronous). HVDC also provides an instant and precise control of the power flow and can increase the AC grid capacity by its stabilizing features.
