Overview -- Interactive PowerFlow Program (IPF):

Interactive Powerflow (IPF) running on the PC platform with various operating systems, including Linux, Unixware, VMS, and MS-Windows 95/98/NT4/2000:

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 14,000 bus network and requires 64 MB (72 MB for Unixware) of virtual storage.

The state-of-the-art Graphical User Interface (GUI) has been integrated into the IPF using the X Window System, the Motif graphical user interface and Motif Window Manager and is available for Linux and Unixware.

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 Linux or Unixware; or accessible via PC's running Windows 95/98/NT4/2000/XP/2003, as a remote terminal using X-Display-Server software such as Hummingbird eXceed, over a network.

The "Batch-Mode-Only" command line interface is available for native MS-Windows versions of IPF through the use of the Cygnus/Cywin operating environment. The GUI user interface is not presently available for use with any of the native MS-Windows platform installations, except as a remote terminal.

In consideration for receipt and acceptance of programs and related documentation, you and your organization agree to advise any third-party recipients (in writing) that the program(s) and/or documentation are in the public domain and available from the BPA, in the event they are sold, assigned, or transferred to other organizations. This process ensures that BPA-developed programs be identified as such to recipients.
