“…Due to the use of 100 Hz harmonic absorption filters the 2 nd harmonic order for an arc furnace distorting consumer has been limited. 2 nd , 4 th and 7 th harmonic order high values have been recorded for the distorting consumer buses corresponding to the electrified transportation system [19].…”

There is an increasing interest in studying the power quality issues. It is sustained by different distorting consumers' operation within the power systems. Their operation affects the supplied power quality within the network, having, in several cases, negative effects for the rest of the consumers. The paper aims to analyze a major power quality issue: large scale consumers' harmonic evaluation, within a specific Romanian Power System region. Solutions for improving the current situation are provided and the numerical simulations are validated using specialized software. The power quality measurements, performed on the field, according to the regulations, have been confronted with the ones obtained using the computer-aided analysis. The conclusions sustained additional studies and analyzes for several operating conditions and scenarios.

“…As real manufacturing domain suffering from harmonic disturbances we quote induction melting furnaces [10] which use electric current to dissolve metal. Where exceeded Harmonic Distortion THD and its moving average TDD compared to the 519_1992 IEEE Standard can cause overloading of power factor correction, over voltage and extra currents, increased error in energy meters, malfunctions of protective gears, relays, circuit breakers, tripping of machines at smaller loads and inductive interference [11][12] with neighboring electrical grid.…”

Currently, we are living in a new transition process towards the fourth phase of industrialization, well known as the purported Industry 4.0. This development backbone supposes a sustainable manufacturing. Were optimal functionalities of a factory components especially energy rationalization and enhanced power quality are nonetheless a privilege but an obligation to introduce efficiently artificial intelligence AI, smart metering SM and automated decision making ADM. In the same axis of mitigating power quality issues, this paper is introduced first to draw innovatively a virtual reality (VR) complex grid connected steel power plant and then to depict harmonic sources in order to moderate them which are caused essentially by nonlinear installed loads manifesting power system quality issues and exhibiting periodic signal distortion. Accordingly, it was essential to assay the diverse origins of harmonic problems and to present the most accommodate and economic solution techniques. Related voltage and current harmonic flows at 30 kV levels, of the General Electricity Company of Libya GECOL located in Tripoli city, are examined. Afterward, inquire jointly their harmful effects on plant components. In order to attenuate distortion, a harmonic analysis has been investigated. Then appropriate filters design have been sized, designed, simulated and appended to the panel. Simulation results are presented and validated using ETAP industrial software under real measurement arena.
