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.

The Relationship

This paper presents the effect of total harmonic distortion (THD) in power factor correction (PFC) at non-linear load. This study focuses on the relationship between THD and PFC. This is beacuse,the power factor affects THD. This occurs in power system as we have variety of loads, i. e linear load or non-linear load. The variety of loads will influence the sinusoidal waveform, which comes out from harmonic distortion. Thus, based on this study, we can compare the effective method in improving the power factor as it will not disturb the performance of THD. The focus of study is on the single phase load, where the voltage restriction is 240 V.  The analysis will  only focus on the consumer, which depends on the variety of non-linear load. Besides, the parameters for analysis are based on the percentage of THD and the value of power factor. The instrument for measuring the parameter is based on power factor correction device or technique. On the other hand, the method that was used for this study is based on simulation which incorporated the Multisim software. At the end of ths study, we can choose the most effective method that can be used to improve the power factor correction without disturbing the THD.
