“…The block diagram representation of three-phase motor drive system is shown in Figure 1. The machinery in industries requires different speed for their operation so this is the reason behind the practice of ASD method for industrial application [10]. VFD plays an important role in the reduction of the harmonics, the distortion rate at the first stage is around 75%, so to overcome that this method is used which is done by IGBT.…”

Most of the fully automated industries are mainly depending on the single and multi-drive system based on their requirements. In this paper, to investigate the power quality problems in a distributed multi drive system connected to the common uncontrolled rectifier is considered. Uncontrolled rectifier is mainly used as a front-end converter to feed direct current (DC) supply to the same rating of two voltage source inverters with induction motors as a multi-drive system. To analyse the effectiveness of the system the two drive systems are operated in different time period. Then, both are operated simultaneously to monitor the power quality issues, due to the front-end converter present in the system. In both the cases the harmonics in source current is not within the limits of IEEE recommended practices. Therefore, to reduce the harmonic content present in the current at source, a shunt active power filter is implemented. The effect of two drive systems operated at the same time is analysed first. Then, active filter is injected in between the source and the multi-drive system in parallel to improve the power quality of the grid system. The individual and multi-drive drive systems are analysed with the simulation results.

“…Sensitive loads connected to the grid are greatly affected by voltage imbalances and harmonics. In the presence of harmonics, motors suffer from overheating, reducing their lifetime, and in transmission lines they cause power imbalance and heating of the lines [ 30 ].…”

The study of power quality (PQ) has gained relevance over the years due to the increase in non-linear loads connected to the grid. Therefore, it is important to study the propagation of power quality disturbances (PQDs) to determine the propagation points in the grid, and their source of generation. Some papers in the state of the art perform the analysis of punctual measurements of a limited number of PQDs, some of them using high-cost commercial equipment. The proposed method is based upon a developed proprietary system, composed of a data logger FPGA with GPS, that allows the performance of synchronized measurements merged with the full parameterized PQD model, allowing the detection and tracking of disturbances propagating through the grid using wavelet transform (WT), fast Fourier transform (FFT), Hilbert–Huang transform (HHT), genetic algorithms (GAs), and particle swarm optimization (PSO). Measurements have been performed in an industrial installation, detecting the propagation of three PQDs: impulsive transients propagated at two locations in the grid, voltage fluctuation, and harmonic content propagated to all the locations. The results obtained show that the low-cost system and the developed methodology allow the detection of several PQDs, and track their propagation within a grid with 100% accuracy.

“…The harmonic caused some troubles, as in research [2][3][4]. Research that decreasing harmonic also has been done in research [5][6][7]. However, the impacts of harmonic tend to be ignored by users because there is no monitoring system for the electrical signal quality provided by the electrical providers [8].…”
