Deployment of power flow control systems
A trailer-based system and related method are described for efficiently transporting, configuring and deploying a power flow control system, including connection to a power transmission line. The system may include preconfigured modules using bolted attachments, hoist rings and a corona ring structure. Standardized clamps are also used. A plurality of power flow control modules is operable while mounted on the trailer. The power flow control modules are configurable to inject reactive power into the power transmission line.
1. A platform for transport and deployment of power flow control equipment, the platform comprising:
a wheeled vehicle;
a plurality of power flow control modules, each comprising at least one impedance injection module to inject reactive power into a power line or at least one fault current bypass module to bypass fault currents of the power line, removably connected to a frame and carried by the wheeled vehicle, at least one of the power flow control modules preconfigured for deployment and including insulating posts for isolating the at least one power flow control module from ground in a deployment mode; and
standardized clamps for connecting one or more of the power flow control modules in a deployed configuration.
2. The platform of claim 1 wherein the wheeled vehicle comprises a trailer.
3. The platform of claim 1 wherein the standardized clamps comprise VISO clamps.
4. The platform of claim 2 wherein the wheeled vehicle includes outriggers for stabilization at an installation site.
5. The platform of claim 1 wherein the power flow control modules further include bus bars having both a solid section and a braided wire section.
6. The platform of claim 1 wherein the platform includes capacity to transport and deploy at least fifteen pre-configured impedance injection modules and at least three pre-configured fault current bypass modules.
7. The platform of claim 1 further comprising one or more of the plurality of power flow control modules having a set of hoist rings for use by a crane.
8. The platform of claim 5 wherein the power flow control modules are configured for attachment to power lines and include corona ring structures.
9. The platform of claim 8 wherein the corona ring structures comprise tubular assemblies having rounded corner attachments.
10. The platform of claim 9 wherein the tubular assemblies have a rectangular shape.
11. The platform of claim 1 wherein the insulation posts enable the at least one power flow control module in the deployment mode to float near line potential of the power line.
12. The platform of claim 1 wherein the plurality of power flow control modules are removably connected to the frame through bolted connections.
