Power system benefits

An HVDC Light transmission can do much more than just transmit power between two points - it can also improve conditions in the connected AC networks.

In the congested power networks of today, where permission for new transmission lines are not easy to get, building a HVDC Light^® cable transmission may give more benefits than just the added Megawatts that come over the DC cable. ABB would therefore want to present some of the power system related advantages HVDC Light can offer.

The following pages describe some of the system aspects where Voltage Source Converter (VSC) technology such as HVDC Light^® can support the power grid. The material is a tutorial for VSC interaction with the AC grid and shall not be treated as a performance specification of HVDC Light.

Efforts have been made to give background information of different power system phenomena and to give an understanding of the possible performance improvements in the grid with the VSC technology.

Take me to the first page of HVDC Light System Interaction Tutorial.
