Applications for Mobile Deployment

The mobile deployment is particularly well-suited for short-term and emergency challenges that network operators face. This includes:

  • Outage windows for construction & maintenance activities
  • Transmission emergencies
  • Short-term congestion
  • Planning uncertainty
  • Bridge solutions

Devices are transported to the site in an standard ISO container.After positioning at the site, the hydraulic lifts raise the six devices.The devices continue to elevate and are turned 90 degrees. Jumpers are attached to facilitate interconnection.At full extension, the devices are ready to be connected to the system.

Since its founding, Smart Wires has been an industry leader in developing rapidly deployable and re-deployable modular FACTS devices. The mobile deployment method represents the fullest realization of those unique aspects of Smart Wires technology, by offering a temporary means of changing line reactance. Both Power Guardians™ and SmartValves™ can be installed using the mobile deployment method. This deployment:

  • Is a containerized solution
  • Can be installed and commissioned in a matter of weeks
  • Requires a limited outage (ranges from hours to days depending on site conditions)

CONSTRUCTION SUPPORT

Resolve overloads to expand outage windows and accelerate construction of transmission projects

SHORT TERM CONGESTION

Resolve overloads to reduce congestion that only appears during a limited time period

TRANSMISSION EMERGENCIES

Resolve overloads from unexpected challenges that occur outside the normal planning process (e.g. unexpected generation closures)

BRIDGE SOLUTIONS

Resolve overloads when permitting or construction is delaying the permanent, long-term solution

The utility in the example below could not secure a long enough outage and caused a 2-year delay for a major project. The mobile deployment lengthens the 6-week outage to 24-weeks, allowing the utility to finish the construction.

Unique Use Case: Manage Outage Windows

The idea of temporarily changing line reactance is a truly novel approach to managing outage windows. Traditional FACTS technologies are too large, inflexible and expensive and require extensive, permanent installation activities to deploy. With the advent of modular FACTS devices floating at line potential and a mobile structure for their deployment and re-deployment, line reactance can be temporarily altered to manage short-term constraints associated with construction and maintenance activities.

Smart Wires’ mobile solution uses power flow control to facilitate and expand outage windows, thereby reducing overall project costs and timelines. Mobile power flow control can enable construction and maintenance projects that were previously infeasible due to restrictive outage windows. The mobile solution can also reduce congestion, curtailment and generation constraint costs that occur during an upgrade or maintenance project.

The mobile platform can be reused on a rolling basis and can be deployed across different voltages across the utility’s grid.

Connecting Mobile

The equipment and methods used for installing the mobile solution are dictated by the particular deployment site conditions and each utility’s requirements and standards. Several different interconnection concepts have been developed by Smart Wires and its engineering partners. Before a transmission line enters a substation, there is a dead-end structure to take the conductor tension. Often this final transmission line structure is located in close proximity to the substation and therefore often utilizes the same accessibility and flat terrain as the substation. Dead-end structures have jumpers which have been identified as a potential place to break the line and interconnect the mobile bank. This has been identified as suitable and preferred interconnection site for the mobile solution, however, Smart Wires collaborates closely with each utility to develop interconnection methods to ensure all requirements are met.
