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.

To comply with European standard regulation (EC) No 842/2006 and 517/2014, which frames the use of SF₆ including handling, filling and working with contaminated gas, the customer decided to deliver theoretical online training before delivering hands on equipment training and manipulation.

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

• 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

Challenge

To bring power from wind farms to the onshore grid.

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 solution gives full control and flexibility in managing the intermitted and variable generation to the load.

Benefits

• Provides lowest loss solution, with the most efficient method of transmission technology
• Enables the controllability of intermittent power
• Maximizes the submarine cable capacity

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.

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

• 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

Challenge

Bring power from remote renewable sources to load centres.

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

• 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

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.

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

• 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
