文摘This paper presents an analysis of the electric power flows in a hot rolling mill plant using a power quality analyzer and developing simulation models with Matlab-Simulink. The model inputs have been taken from process data by the process computer of the plant. Data from different rolling campaigns have been analysed.

The overall electric model has been simulated with the STATCOM to check the improvement in the voltage stability and the consumption.
