Priyo Sasmoko, in this paper explain that the need of electric power recently progressively complex, not only the requirement of availability of electricity, but the quality of energy have become prime facie demand. Studies of electricity quality have been conducted by many experts, one of them is about harmonic. Harmonic represent waving current or tension which is tension distortion at electric power system mains so that can result unideal waveform. The study of harmonic required appliance or obyek which need to be checked. In this research Simulator Generator Harmonik is made  a harmonic generator module which can deputize the appliance or obyek yielding harmonic with harmonic component and the THD which can be varried. This module works by dividing one cycle of mains become some slots so it can be got harmonic component as desired. To change the THD,a variation of linear load is used so that the ratio of non-linear load current can be varried. Keywords : Simulator, Harmonic component, THD

The purpose of the work is developing a simulation model of factory’s the power system, with a nonlinear load model, which is a 12-pulses thyristor invertor and a model of a static synchronous compensator, which is multi-level voltage invertor, based on H-bridge invertor. Also defining preliminary parameters for the design of a static synchronous compensator in order to meet the requirements for power factors and limits of voltage harmonic and interharmonic distortion specified for the point of common connection to the mains supply. The analytical and numerical methods of mathematical programming and control of electromechanical systems were used. VisualStudio and PSIM software products for developing a control system for electromechanical systems and compiling a simulation model of an industrial power supply system were used. As a result of the research, a simulation model of the power supply system of an industrial enterprise, a model of a nonlinear load and a static synchronous compensator were developed. The rated power of the static synchronous compensator is determined to reduce the consumption of reactive power and the magnitude of the higher harmonics of the current, at the point of common connection, during operating a non-linear load.
