Simulating the Operation of a Filtering&Compensating Device in a SimInTech Environment

Due to the increasing share of nonlinear load in electrical networks, the total coefficient of harmonic components increases. At the initial stage of work to improve the quality of electrical energy of a particular facility, instead of instrumental inspections, it is possible to use a virtual computer model based on a real power supply scheme. The article analyzes the influence of higher harmonics on the quality of electricity, discusses the methods and operation of the higher harmonic filter model to reduce the non-sinusoidal supply voltage. SimInTech software libraries are used as the basis for modeling. The virtual model allows you to change the parameters of the external supply network and load in real time for any specific object with a preliminary calculation of the substitution scheme. The simulation results showed that in the studied modes, the distortion coefficients of the non-sinusoidal current decrease to acceptable values when the filtering&compensating device is turned on.
