The Distribution Feeder Network Analysis Program system (DIFNAP) is a system of programs which have been developed to analyze power line distribution systems. They are of primary use in the analysis of Radio Frequency Propagation over power line distribution systems. The present group of programs permits the computation of voltages, currents, power, source admittances, and driving point admittances in a multiconductor distribution system primary. The power line distribution system may consist of 3-phase or single-phase overhead or underground transmission lines or single-phase, phase-to-phase takeoffs. The equipment on the feeder can consist of capacitor banks, distribution transformers, ratio-bank transformers, three-phase high voltage loads, or voltage regulators. The principal part of the DIFNAP system consists of two main programs. The first, called NTWKERS1, computes the voltage transfer ratios and driving point admittances of each section of the line. The second program, called NTWKANS1, uses the results of the first program to compute the voltages, currents, and power of the input of each section of the line leading up to the section where the user desires to have these quantities determined. This program allows the user to determine the effects of opening sections, faults, inserting additional loads, and inserting or removing compensation capacitors on the line. This perturbation calculation feature is possible without the need to completely reanalyze the entire network. Details of the DIFNAP system and the two network programs, are presented.
