Key Benefits

• Reliability enhancements through real-time detection of unstable system behavior

and isolation of the affected system ensuring your most critical infrastructure stays

online until normal system operation is restored

• Improve Resiliency by providing a system that can self-isolate from the affected grid

and continue to support its loads independently for desired periods of time

• Energy Cost Reduction through a solution that can efficiently manage and optimize

your energy resources based on real-time energy market prices, operational costs and

energy resource mix

• Increase Revenue providing the capability to your system to provide ancillary services

to the grid such as Frequency Control, Reserve Capacity, and Demand Response

• Energy Security by effectively controlling, monitoring and optimizing your local energy

assets reducing your need to rely on a centralized supply

Multi-terminal HVDC systems and DC Grids

Challenge

Interconnect three or more regions and power systems to facilitate power

exchange and trading, and to provide added system security, efficiency and

flexibility to the benefit of the overall grid.

GE’s solution

GE’s HVDC enables the interconnection of multiple HVDC converters

providing controllability of power flow and facilitates the future expansion

into HVDC grids.

Benefits include

• Better management and integration of renewable energy generation

• Increases grid security

• Enables cross border energy trading

• Provides more efficient network by reducing reliance on thermal generation

Connecting Renewable Generation

Challenge

Bring power from remote renewable sources to load centres

GE’s solution

GE’s HVDC LCC and VSC are amongst the most economical and feasible

solutions for connecting renewable generation applications, such as wind,

hydro and solar power. GE’s solution gives full control and flexibility in

managing the power flow from the intermittent and variable generation to

the load.

Benefits include

• Provides a low loss solution, with the most efficient method of

transmission technology

• Enables the controllability of intermittent power

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

of way requirements

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

HVDC Applications

Connecting Offshore Wind

Challenge

Bring power from distant wind farms to the onshore grid.

GE’s solution

GE’s HVDC VSC technology is the most economical and feasible solution for

connecting submarine cable applications, such as offshore wind farms. GE’s

• Optimizes the use of submarine cables

Infeed Urban Areas

Challenge

To get power into congested cities to address increasing demand, lack of

power highways and difficulties with establishing rights of way for a new grid.

GE’s solution

GE’s VSC HVDC technology is ideally suited to provide controllable

and efficient power into congested areas where small footprint and

environmentally acceptable solutions are essential.

Benefits include

• Minimizes the visual impact of the power infeed on the local landscape

• Provides high levels of power injected directly to where it is needed

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

interconnected networks

• Provides lowest loss solution, with the most efficient method of

transmission technology

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

GE’s HVDC Technologies

Line Commutated Converters

Line Commutated Converter is a mature cost effective HVDC technology

based on thyristor power semiconductors, which enables the bulk transfer

of power of up to 8 GW with low losses and inherent DC fault protection.

LCC is available as point to point overhead line and submarine/land cable

and is ideally suited for back to back schemes.

Voltage Source Converters

Voltage Source Converter is a newer technology based on power transistors

with a reduced footprint compared to LCC technology. VSC is an ideal

technology for submarine/land cable interconnection, integrating renewables,

offshore and urban infeed applications. VSC is available as point to point,

back to back, submarine/land cable and offshore schemes. VSC has distinct

technical advantages over the traditional LCC schemes because it creates

an AC waveform that allows the scheme to control real and reactive power

independently and transmit real power into a very weak AC network,

which is not possible with LCC.

HVDC Schemes

Back to Back Scheme

Suitable for frequency changing and asynchronous connections. This

scheme provides fast accurate power flow, limiting the spread of cascading

faults and provides increased system flexibility relative to new generation

requirements. Once interconnected, the two systems’ daily and seasonal

cost differences can also be optimized.

Point to Point Scheme

Commonly used for bulk transfer of power applications utilizing overhead

lines over long distances providing low cost, fully functional, reliable and

environmentally friendly way to transmit power.

Submarine/Land Cable  Scheme

Where the power exchange or transmission crosses water, or an

environmentally sensitive region, cables may be the favored method of

interconnection between the HVDC Converter Stations. HVDC transmission

is particularly attractive and may be the only technically feasible method of

transmitting power using cables.
