Rendered Triangles: Triangles filled with color as a function of elevation and line of sight Contours: Contour lines at user specified intervals Triangles: Triangulated surface passing through surveyed points This animation cycles through 5 different representations of the same terrain: In PLS-CADD you concentrate on designing your line instead of wasting your time drafting. The effects of this structure move will be instantly visible in all views including the plan & profile sheet view.
Pls cadd modeling update#
When you drag a structure off the current alignment PLS-CADD will generate new profiles and update all affected structure and wire positions. The PLS-CADD model is much more than just a picture or CAD drawing since PLS-CADD understands the relationship between these elements.
The model can be viewed in a number of different ways: profile views, plan views, plan & profile sheets, 3-D views, staking lists. This model includes the terrain, the structures and all the wires. This image was created by "draping" the same photo shown in the left pane over a digital terrain model.Īt the heart of PLS-CADD is a sophisticated three-dimensional engineering model. The left pane of the image shows an isometric view of the same section of line in the right pane. The contour lines were generated from the digital terrain model and can be displayed at user selected intervals. The right pane of this image shows a top view of a line superposed over an aerial photo. The PLS-CADD solution is so clearly superior to any alternative that it has been adopted by more than 1400 organizations in over 115 countries. This sophistication and integration leads to more cost-effective designs being produced in only a fraction of the time required by traditional methods. No other program can match the sophisticated engineering capabilities available in PLS-CADD. It integrates all aspects of line design into a single stand-alone program with a simple, logical, consistent interface.

PLS-CADD runs under Microsoft Windows and features an easy to use graphical user interface. When line construction was complete, nearly 80 structures out of the existing 108 in that section were replaced.PLS-CADD is the most powerful overhead power line design program on the market. SGC assisted BHE in providing timely construction support when conditions forced adjustments.
Much of the line was routed through areas that had been designated for frozen conditions during construction due to minimize wetland impacts. SGC supported the construction effort during a difficult winter for line building work. SGC’s PLS-CADD model of the existing line proved very accurate in developing the sagging tensions during construction. The new, taller structures allowed for the conductor tension to be reduced slightly, minimizing strain on the old line. The line was redesigned using the existing conductor. The design included three new dead-end structures, creating four tension sections. The damaged section was rebuilt but this final section remained at risk to those same conditions. This project started at a point just beyond a section that had been leveled due to the cascade effect caused by the infamous ice storm of 1998. SGC created a plan for the line that allowed new structures to be placed outside the wetlands when practicable.Īnother facet of the design was the creation of dead-end sections to improve reliability. BHE’s plan was to leave as many existing structures in place as possible. In working with Bangor Hydro Electric Company (BHE), SGC developed a plan for structure replacement based on pole conditions.
Using a combination of LIDAR, survey, and original plan and profile drawings, a model of the existing line was created in PLS-CADD. SGC designed the rebuilt 115kV line section of approximately 12 miles in the Downeast region of Maine. East Epping to Washington County Substation
