Power Quality, Harmonics Mitigation & Reactive Power Management

introduction
The ever-increasing advancement of semiconductor-based power electronic devices and nonlinear loads, as well as rapid integration of non-conventional energy sources into grid networks can create harmful power quality issues in industrial systems and utility grids. To name a few, power electronic equipment, data servers, variable speed drivers, arc furnaces, big machines such as heavy-duty cranes, lifters, motor-driven conveyor belts, and large numbers of fluorescent lamps can cause catastrophic power quality issues in electrical power systems.
Electric parameters such as frequency and voltage magnitude / waveform / symmetry are normally influenced by the variations of load during normal system operation. These characteristics are also affected by system disturbances – e.g., harmonic distortion and voltage fluctuations – generated by certain equipment, and also by electric faults such as arc flash or switching transient overvoltage’s.
