The Impact

Non linear load harmonics cause, Air Conditioning is one of the main types of inverters that generate non linear load harmonics. Harmonics on the Air Conditioning so that the reduction must not interfere with the quality of power on the system and network. The ability of an Air Conditioning unit to cool a room can be known as Coefficient Of Performance (COP). This can be seen from the comparison between the heat energy required to cool the room with the electric energy used on the unit. In this case you will know the impact caused by the reduction of the harmonics of the COP. Reduction of harmonics used in this study using 16 F capacitor which also serves as a power factor improvement. The results obtained after using the capacitor found impairment harmonic currents (IHDi). After the measurement of the COP also increased from 2,740 becomes 3,176. This proves that the capacitor also function besides improving the power factor can reduce the harmonics an improve the COP.

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.
