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.
