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

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.
