Abstract
This research addresses a key aspect of improving the quality of electric power to tackle the distortion due to the widespread use of power electronics systems in particular, nonlinear loads in general, as well as addressing the loads of influence on power factor. The analysis and representation of new system using MATLAB and combining two functions of static synchronous reactive power compensation, STATCOM, and active power filter, APF, in one unit.
The proposed system has the ability to control the reactive power flow in power schemes and also reduce harmonics at the same time by compensating all of the imaginary part of the load current and harmonics. This system is named as Static Reactive & Distortion PowerCompensation(SRDPC).The circuit control system SRDPC, enabled Random Pulse Width Modulation(RPWM), is obtained according to the equations have been derived for this purpose. The results of the analysis and representation of the system SRDPC that have the ability and efficiency in improving both power factor and shape of the supply current waveforms power within allowable standards for linear and nonlinear loads.
