“…This is, as expected, the same as equation 10.15 for the bridge rectifier case. The characteristic harmonics, group current rating and supply transformer MVA rating are thus the same as in equations 10.18-10.22.…”

“…Equation 10.9 gives the desired output I d1 in terms of measured inputs and rectifier parameters. Although the output is in terms of I 2 d1 this makes no difference to the control method, and allows the relationship to be considered as linear.…”

“…The upper comparator performs the increment function as in equation 10.44 and the lower performs the decrement function as in equation 10.45. The actual comparison block works as follows: when signal A increases to the point where it exceeds signal B, a pulse is output.…”

“…The main supply transformer (Tx 1 ) is rated at 200 MVA, 220 : 33 kV and feeds each of the thyristor phase-shifted transformers and the MLCR threewinding star-delta transformer, their secondary voltages being 0.8 kVand 7.6 kV respectively. The MLCR transformer ratio is calculated using equation 10.50, and all transformer leakage reactances are specified as 5%.…”

Smelting requires extremely large DC currents, often in excess of 320 kA, to facilitate the production of commercial quantities of aluminium using the reduction process. The DC load consists of one or more potlines, which in turn are made up of many series-connected reduction cells, often in groups of 250 or more. Each cell has a nominal operating voltage which is controlled to around 4.0-4.5 V. The reduction cell is constructed with a movable carbon anode, electrolyte, aluminium cathode, cathode carbon and steel collector as shown in Figure 10.2. Figure 10.2 Simplified schematic of an aluminium reduction cell.
