AMSC’s D-VAR® and SVC Smart Grid Solutions

• Scalable dynamic power grid voltage stabilizers

• Proprietary control systems optimized for grid integration

• Able to significantly boost power grid capacity and enhance reliability

• Address growing worldwide transmission grid requirements

D-VAR System

SVC System

Both provide intelligent, automated and real-time power grid control

Dynamic Reactive Solution:

AMSC D-VAR® STATCOM

• Most widely deployed

STATCOM in the world

• Overload capability provides

for post-fault voltage recovery

• Built-in redundancy protects

against downtime

• Scalable design allows for

simple upgrades

• Minimal harmonics

• Incremental servicing capability simplifies maintenance

AMSC has deployed more STATCOM systems than all other companies combined

Dynamic Reactive Solution:

Static VAR Compensator (SVC)

• Passive design maximizes reliability

• Factory - built modules eliminate

– Routine maintenance

– Water cooling

– On-site valve assembly

• Controls integrate switched capacitor/ reactor control for Total SVC systems

Transmission and Distribution SVCs scalable from 10’s to 100’s of MVAR

AMSC Dynamic Reactive Compensation

• More STATCOM FACTS devices installed than any other supplier. AMSC D-VAR® and SVC applications include utility voltage regulation support, wind farms, large loads (mines), utility voltage collapse prevention, reduction of reliability generation run time (RMR), as well as flicker and sag mitigation.

• AMSC’s team of engineers provide over 80 years of utility transmission planning and engineering experience. They are experienced in loadflow, stability, and harmonic analysis and in using PSS/E, PSLF, DIgSILENT, PSCAD and PowerWorld softwares.

Grid Studies performed for utilities and wind farms worldwide
