CIMA+ prepared the design basis and the power system study (analysis and validation), and also provided technical support for the compensation banks and harmonic filters: 12 new 25 MVAr banks were installed at 10 kV, thus increasing the mill’s total power consumption from 715 to 815 MW (at the 230 kV substation).
In anticipation of a production increase at the Bécancour mill, the power system study was essential for the purpose of providing the necessary assurances to Hydro-Québec Transport with respect to compliance with its connection requirements. The existing mill equipment and the sub-components of the new compensation banks were also analyzed in detail.
