DVC™ - Dynamic VAR Compensator Solutions

DVC™ - Dynamic VAR Compensator Solutions  

American Superconductor's (AMSC™) DVC (Dynamic VAR Compensators) solutions are based on the widely successful D-VAR® system.  They are a hybrid STATCOM/SVC solution that utilizes inverter-based FACTs (Flexible AC Transmission systems) technology similar to D-VAR systems along with proprietary fast-switched capacitors and reactors.  AMSC has developed DVC solutions to address the need for large-scale solutions requiring hundreds of megaVARs (MVARs) of reactive compensation.

The DVC systems are modular and scalable.  They can be customized to meet any dynamic reactive compensation need and are built in sizes ranging up to several hundred MVAR connected to a single point on the transmission grid.

The illustration below shows the basic configuration of a typical DVC solution.  The combination of proven inverter-based dynamic VARs and fast-switched shunt elements provides large-scale DVC solutions that have high availability and performance and are more cost effective than STATCOM and SVC solutions.  The AMSC D-VAR® modules at the heart of the DVC solution have a proven track record in the field and have performed with the highest of reliability.

AMSC's PowerModule™ power converters are the building blocks that make up the D-VAR systems that are integrated into the DVC system.  These inverters are highly power dense and have transient overload capability which allows the DVC solution to be even more cost effective.

DVC systems are modular and easily expandable to meet ever-changing grid conditions and customer needs.  DVC solutions can help address reactive compensation problems for various applications. Some of the applications include:

Steady-state Voltage Regulation - radial line, wind farms

Import / Transfer Capability Restrictions - limited ability to reliably import, export or transfer power
