HFMS: Soft for Calculating and Simulating Harmonics Distortion and Passive Filters

Abstract

Due to harmonics phenomenon occurs on power system, harmonics filter needs to be installed into power system to mitigate and suppress harmonics distortion. In order to know the effect of installing harmonics filter, feasibility study needs to be done. Before conducting the study, some parameters and real harmonics data have to be measured and collected from power system, then input them into software for simulation. Most software used in feasibility study has been developed such as ETAP, PSIM, OrCAD, DigSILET, etc. Unfortunately, those software programs only provide the harmonics data of power electronics from their library and can’t conduct simulation using measured harmonics data from real condition on the power system. This paper contributes the development of a new software, Harmonics Filter Modelling Software (HFMS), which has been developed especially for simulating the harmonics distortion based on measured data on power system. This helps engineer to make feasibility study more accurately because it uses measured data from real condition on power system. In addition, HFMS is capable to compare the harmonics measured data with the harmonics limits based on standard IEEE 519TM-2014. It is also adequate to calculate four kinds of harmonics passive filters (single tuned filter, double tuned filter, damped-type double tuned filter, and c-type filter) automatically based on measured data. Last, it is able to simulate the effect after the filter is installed into the power system. HFMS has been validated using PSIM software and the result shows that HFMS works properly and has similar result.
