SmartValve™ with Integrated Bypass
The SmartValve™ 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. A modular,
Static Synchronous Series Compensator (SSSC), the SmartValve 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, the SmartValve can inject the voltage independently of the line current, thus
increasing the ohmic injection when operated below the rated value. Also, the SmartValve does not have the negative
characteristics of these passive devices, such as the 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 dynamic needs of the transmission grid. Given the fast
response of the unit’s power electronics, the unit can provide dynamic services and its set-point can be changed
frequently to actively manage power flows with no degradation in unit life.
The SmartValve enables utilities to get more from their existing grid by:
Addressing short-duration and emergency needs with rapidly deployable and easily re-deployable solutions
Accommodating changes in generation and load by deploying a fleet of units in weeks rather than years
Pushing power away from overloaded transmission facilities or pulling power onto underutilized facilities
Avoiding the use of precious substation space
Providing high uptime via a modular solution with no single point of failure
The SmartValve is available with 10 MVAr and 16 MVAr ratings. The first number in the Model number designates the
MVAr rating, the second is the maximum continuous current rating, the “i” indicates that a bypass is incorporated within
the SmartValve and the third number is the 1 second fault rating in kA RMS. For example, Model 16-2700i-63 has a
reactive power rating of 16 MVAr, a maximum continuous current rating of 2700 A RMS, an integrated bypass and 1
second fault current rating of 63 kA RMS. These units are typically installed as part of a fleet and enable a continuous
range of control up to the collective rating of the deployment.
