SmartValve™ 10-1800 v1.04

The SmartValve 10-1800 v1.04 builds upon the success of its predecessors. By using revolutionary power

electronics, the SmartValve effectively increases or decreases the reactance of a given circuit, enabling real-time

control of power flow. SmartValve is a modular, Static Synchronous Series Compensator (m-SSSC) that injects a

leading or lagging voltage in quadrature with the line current, providing the functionality of a series capacitor

or series reactor respectively. However, unlike conventional series capacitors or reactors, SmartValve can inject

the voltage independently of the line current, thus increasing the ohmic injection when operated below the rated

value. Also, SmartValve does not have the negative characteristics of these passive devices, such as high risk of

sub‐synchronous resonance (SSR) with series capacitors and the constant VAr consumption of series reactors.

As a modular device that can be deployed and re-deployed, the solution size of an installation can be scaled up

or down to support the changing dynamic needs of the transmission grid. Given the fast response of the device’s

power electronics, the device can provide enhanced services, such as transient stability support, and its set point

can be changed more frequently than legacy solutions to actively manage power flows with no degradation in

device life.

SmartValve enables utilities to get more from their existing grid by:

• Accommodating changes in generation and load by deploying an installation in weeks rather than years

• Addressing short-duration and emergency needs with rapidly deployable and easily re-deployable

solutions

• Pushing power away from overloaded transmission facilities or pulling power onto underutilized

facilities

• Minimizing the use of precious substation space

• Providing high uptime via a modular solution with no single point of failure

The SmartValve 10-1800 has a maximum continuous rating of 10 MVAr and a maximum continuous current

rating of 1800 A RMS. The device is equipped with an integrated bypass and can withstand fault currents up to

63 kA for 1 second. Additionally, this product is available with three option packages, the Enhanced-Availability

package, the Fast-Transient Injection package, and the Fiber-Optic package.

SmartValves and corresponding communication equipment are typically installed as part of a SmartValve

System. The SmartValve System enables a continuous range of control between the minimum injection

voltage of a single device per phase up to the aggregate maximum injection voltage rating of all devices in

the system.
