The number of nonlinear loads connected to power distribution systems is rapidly increasing. These loads disturb the sinusoidal nature of the power distribution systems to which they are connected. Consequently, all connected loads may be affected by even a single nonlinear load. This makes power quality an increasingly important issue, particularly in shipboard applications because equipment malfunction can cause the loss of life. This study primarily develops a modeling technique for use with the harmonic power flow program (HARMFLO) developed by the Electric Power Research Institute. A land based power distribution system is modeled and simulation results are compared to field measurements. Additionally, the causes and effects of harmonic disturbances in power distribution systems are reviewed. In spite of the fact that many parameters of the system being modeled are not precisely known, simulation results are similar to the field measurements. This implies that HARMFLO has applications in isolating existing harmonic disturbances of installed systems and impact assessment for planned systems with one or more nonlinear loads.
