Compact High Voltage Direct Current (HVDC) Transmission

A major driver for developments of new offshore HVDC connections is the ability to decrease the size of the station. Optimization of the converter station may reduce the size with 50%, which drives down cost of the platform. One component to reduce the size of the station is to shift from air insulated DC switchyard to DC-GIS.

HVDC Transmission: Part of the Energy Solution?

• HVDC links can stabilize AC system frequencies and voltages, and help with unplanned outages. • A DC link is asynchronous, and the conversion stations include frequency control functions. • Changing DC power flow rapidly and independently of AC flows can help control reactive power. • HVDC links designed to carry a maximum load

High-voltage direct current - Wikipedia

A high-voltage, direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current for the bulk transmission of electrical power, in contrast with the more common alternating current (AC) systems. For long-distance transmission, HVDC systems may be less expensive and suffer lower electrical losses.
