A User-Oriented Power Distribution System Analysis Program.
Abstract
This paper is a revision of a digital computer program written to perform a load flow and/or short circuit analysis of a power distribution system. The program has been named Power Distribution System Analysis Program (PDSAP). The program capacity is 250 buses and 500 line elements, with 250 of the line elements being transformers. Input routines accept data as impedances (ohms or per-unit), or as descriptive information such as wire size, length, or transformer ratings. For descriptive data, the program uses pre-calculated approximations to derive the impedance values for the various due to neutral conductors in the system. The load flow routine uses the fast-decoupled Newton-Raphson technique and has the capability of changing loads to represent load growth within the system. The short circuit routine analyzes systems in 50 bus groups, simulating various types of faults for each bus. Bus voltages and line currents in the system are calculated for each simulated fault.
