Power supply quality improvement: harmonic measurement and simulation

Dalila Mat Said, Nasarudin Ahmad, Abdullah Asuhaimi Mohd Zin

Abstract

This paper presents the harmonic measurement and simulation in a power distribution network and then gives suggestion of filter installation to improve harmonic distortion. The specific case study has been conducted at Faculty of Electrical Engineering, UTM building where nonlinear loads such as computers and fluorescent lamps which produce the harmonics are connected. Measurements are conducted at each subswitch board (SSB), main-switch board (MSB) and substation of the faculty. The selected networks are modelled and simulated using SKM-Power Tools for Windows software. The results from the measurement are compared with the simulation result, and it is found that there are quite close to each other. Based on the simulation, harmonic distortion improved after filter installation.
