SIMPOW integrated in NEPLAN

BCP (Busarello+Cott+Partner Inc.) and STRI have integrated the Simpow dynamic analysis modules in the NEPLAN planning and optimization software. Simpow users are now profiting from one of the best planning and optimization software, which provides an advanced graphical interface and the possibility to expand the program package with a lot of different calculation modules such as relay selectivity analysis, reliability analysis and optimal maintenance planning, see the list of modules below. The new integrated version of Simpow in NEPLAN is available from September 2005. The combined package is one of the most complete power system planning and optimization tools on the market. BCP and STRI are also collaborating with support, marketing and sales of their respective software. For further information, please contact BCP or STRI.
