The 21st century’s
biggest energy challenge is delivering electricity to the end users with the
lowest losses possible while maintaining a high quality level. For older
networks, equipment and transmission losses can be very high and network
managers need quick return-on-investment solutions to improve quality and
offers its customers solutions to save energy and to improve power quality by
reactive power compensation and harmonic filtering.
electronics-based equipment, including the Flexible AC Transmission System
(FACTS), provides proven, dynamic and cost-effective solutions
to address these new operating challenges.
FACTS high-voltage AC transmission solutions are widely
recognised by network suppliers and industrial energy managers. Grid operators
can gain accurate control of reactive network power, maximise power flow along
existing lines and improve steady-state and dynamic stability with the
Flexible AC Transmission System (FACTS) technologies provide the customer
with a flexible solution that has minimal infrastructure investment, low
environmental impact and rapid implementation time.

As one of the world’s leading providers of grid solutions and
a global leader in power electronics, Alstom Grid has developed a range of
cost-effective solutions to ensure optimal power quality and security. Power
quality optimisation means asset utilization maximisation, enhanced service
quality and reduced operating costs. Our comprehensive portfolio of FACTS
devices is dedicated to enhancing the power quality and performance of our
customers’ high-voltage AC transmission systems around the world.
Alstom Grid FACTS solutions include:
MSCDN (Mechanically Switched Capacitors with Damping Networks): proven technology to provide a switchable source of reactive power to stabilize low frequency voltage variations.
Fixed and Relocatable SVCs (Static VAr Compensators): dynamically variable sources of reactive power to stabilise the voltage, damp system instabilities and reduce flicker for both transmission and industrial applications.
STATCOM: highly dynamic voltage source converter-based compensators which, compared to SVCs, offer improved range of operational voltage, a faster response and a smaller site area.
FSC (Fixed Series Capacitors): switchable banks of capacitors inserted in series with a line to compensate for the inductive voltage drop, effectively increasing the line length.
TCSC (Thyristor Controlled Series Capacitors): similar to FSCs but provide dynamic power flow controllability and can mitigate the effects of sub-synchronous resonance.
