Electrical Power Quality of Iron and Steel Industry in Turkey

Mobile monitoring system to take nationwide PQ measurements on electricity transmission systems

“…Having observed 2nd harmonic amplification problem at the iron and steel industry plants as a result of the investigation of the problem [10]. Raw data for approximately two hours have been collected at five different plants and this data has been analyzed using the mobile PQ monitoring software.…”

“…16 points out a harmonic amplification problem at the supply current (I s ) from the EAF current (I EAF ) owing to SVC type flicker compensation system around the 2nd harmonic component of the power frequency. Details of this problem-specific mobile PQ measurement are given in [10].…”

“…These kinds of measurements are usually based on raw data collection and the evaluation of data collected in the field permits the development of countermeasures to improve PQ at those points. For instance, impacts of single and multi-electric arc furnace (EAF) operations on PQ in electricity transmission system have been determined by this way [10].…”

“…Mobile PQ monitoring is an on-going process, and after one-week PQ measurements are completed all over the country, critical points in terms of power quality will be determined and permanent monitors will be connected at those transformer substations for continuous monitoring [11,12]. In addition to the routine one-week measurements, problem-specific measurements are being carried out at transformer substations that exhibit critical characteristics in terms of PQ of the electrical transmission network, such as arc furnaces [10]. …”

Adaptation of renewable based power plants to the energy market using battery energy storage systems

“…This means supplying electricity to nearly 20,000 houses. The most important point about choosing this station for the study is that the wind power generation data for the year of 2011-2012 are available as sets of 10 minute-average values, thanks to the TÜB TAK MAM Energy Institute's Power Quality Analyzer (PQA) Project [14]. Therefore, it became possible to test the solution in a real situation.…”
