ASPEN Power Flow™ is a full-featured, PC-based power flow program designed for the planning, design and operating studies of transmission, sub-transmission and distribution networks. The easy-to-use graphical interface makes it an ideal tool for investigating the effects of network reconfiguration and temporary outages on power flow, system losses, area interchange and circuit overloading. The following are some highlights of the Power Flow Program:

• Native Microsoft Windows program.
• Easy-to-use interactive graphics interface under Windows 7, 8 and 10.
• Accurate modeling of 2- and 3-winding transformers, phase shifters, lines, switches, series capacitors and reactors, generators, loads, capacitors, reactors, switched shunts and dc lines.
• Robust automatic-control algorithms for generator voltage regulation (local and remote), transformer load tap changers, phase shifter MW controllers, switched shunts, and area-interchange constraints.
• Unlimited system size with modest memory requirement.
• Lightning fast solution speed.
• Graphical display of solution on the one-line diagram.
• Graphical warning of branch overloads and voltage violations on the one-line diagram.
• High-quality printed outputs on a large variety of printers and plotters.
• Bus-by-bus solution report in various formats.
• Summaries on area interchange, voltage violations, branch overloads, LTC transformers, generator outputs, and loads.
• Data importing facilities from network data in ANAREDE, GE, PTI (PSS/E and PSS/U) and other formats.
• Data exporting facilities for ANAREDE, PTI PSS/E raw data files and GE PSLF files.
• Built-in scripting language using the BASIC programming language.
• Scripts for contingency studies and power transfer-limit studies.
• Easy-to-use N-1 contingency studies.
• Proven reliability at major utilities in the U.S. and abroad.
