Reliability and stability

Alstom Grid offers innovative solutions to meet customer needs.

Deregulation in the power industry and the need for more efficient energy has created additional requirements for power system operators. High Voltage Direct Current transmission (HVDC) and flexible ac transmission systems (FACTS) offer major advantages in meeting these requirements.

Ultra High Voltage (UHV) is the future of electricity transmission. One of the dilemmas facing governments and utilities today is how to supply large amounts of electrical energy for growing populations in a way that is both efficient and has a minimal impact on the environment.

Flexible Alternating Current Transmission Systems (FACTS)
FACTS devices provide strategic benefits to improve transmission system management through better utilization of existing transmission assets. FACTS increase transmission system reliability and availability, grid stability, quality of supply for sensitive industries and enabling environmental benefits.

FACTS can be considered as an alternative to the construction of new transmission lines to face the increasing demand of energy without damaging the supply quality.

High Voltage Direct Current (HVDC)
HVDC schemes offer a technical and economical alternative to classical AC lines for the transmission of electricity generated remotely from the load. Depending on distance and power transmitted, HVDC offers substationally reduced losses leading to a more efficient network. In addition, HVDC acts as a firewall against faults, effectively eliminating blackouts.

As offshore wind farms increase in size and are installed further from the shore, HVDC becomes the only option for to connect this environmentally friendly source to the power grid.

Ultra High Voltage
Regardless of the source (hydro, thermal or nuclear) UHVDC presents efficient and cost effective transmission of very high levels of remotely generated power over very long distances to the load centers.

UHV significantly reduces overall investment costs, transmission losses and right-of-way (ROW) land requirements while maintaining all of the operational benefits of HVDC.
