Digital Simulation of Distribution System Frequency-REsponse Characteristics

A new digital computer program developed for harmonic analysis of multi-phase networks is described. The program-the Distribution Feeder Harmonic Analysis (DFHA) Program-is designed to conveniently model distribution systems to determine frequency-response characteristics. Results of simulations performed for two different distribution systems are compared with actual harmonic measurements on the systems. Simulation accuracy is evaluated and guidelines are presented for modeling a distribution system and performing the digital harmonic analysis.
