Interactive PowerFlow Program (IPF), ver. 3.27 for LINUX:

Interactive Powerflow (IPF), version 3.27, running on the PC platform with the LINUX operating system. This covers hardware requirements for computer system PC setup, pre-compiled IPF program executables and source code installation for Linux.

IPF Version 3.24 has been tested with the following Linux distributions: Redhat 5.1, Redhat 5.2, Redhat 6.0 and Redhat 6.1.

IPF Version 3.27 has been tested with Linux distributions: Redhat 6.1, Redhat 6.2, Redhat 7.0, Redhat 7.1, and Redhat 7.2.

NOTE: Recent tests with Redhat 7.3 and 8.0 have shown the compilation of the IPF GUI to be partially incompatible with IPF. Versions of the IPF GUI compiled on Redhat 7.2 or earlier will run on Redhat 7.3 and 8.0. We hope to solve this situation in the near future.

OTHER SUCESSFULLY TESTED LINUX DISTRIBUTIONS FOR USE WITH IPF: Conectiva Linux 7.0, Mandrake Linux 8.x

The Interactive PowerFlow Program models the balanced steady-state operation of an electric power network. It is used by power system planners and design engineers to investigate electric power networks, determine bus voltage distribution, line real and reactive power flows, line overloads, system reactive requirements, area controls, effect of load shedding, generator dropping, and line outages.

Currently, the program efficiently uses computer resources through the implementation of advanced techniques of large system analyses, including the Newton-Raphson method for solving second order algebraic equations and sparse-matrix computation techniques. Typically, it solves a 12,000 bus network and requires 72 MB of virtual storage. The state-of-the-art Graphical User Interface (GUI) has been integrated into the IPF using the X Window System/Motif.

The IPF runs on various platforms which support the X Window System/Motif - Window Manager, Graphic User Interface. At BPA, IPF is used on VAX/VMS mainframes, VAX/VMS Stations, DECStations, DEC-Alpha, and properly configured PCs running Unixware or Linux. For PC’s running Unixware or Linux the recommended minimum configuration is:
