HVDC Applications

Transferring Bulk Power Over Long distances

Challenge

Transfer large amounts of power from distant power sources, such as hydro

plants, to a load centre.

GE’s solution

GE’s HVDC LCC point to point scheme is ideal for the bulk transfer of

power utilizing overhead lines over long distances providing a fully flexible,

controllable and environmentally friendly solution for transmit power.

Benefits include

• Maximizing transmission of substantial power utilizing UHVDC up to 800kV

• Improves environment impact as a result of the smaller towers and right

of way requirements

• Increasing power capacity up to 3 times more than AC circuits

Interconnecting Grids

Challenge

Interconnect asynchronous AC electricity grids to enable energy exchange,

which provides dynamic reserve power support, relieve energy bottlenecks

and maximize the efficient use of available power.

GE’s solution

GE’s HVDC back to back schemes are ideal for interconnecting grids

operating at different frequencies, not synchronized, operating at high

power and in extreme temperatures up to +55° C.

Benefits include

• Exchanges energy between two unsynchronized AC systems

• Provides fully controllable and flexible dynamic reserve power support

• Manages fault propagation providing a power “firewall” between the

interconnected networks
