In single compensation, the capacitors are directly connected to the terminals of the individual power consumers and switched on together with them via a common switching device. Here, the capacitor power must be precisely adjusted to the respective consumers. Single compensation is frequently used for induction motors (Figure 4).
Depending on the size of a compensation unit, it is assembled with capacitors of equal size (in bigger units) or of different size. A unit with a total reactive power of, for example, 300 kvar consists of six power capacitors, of 50 kvar each. Thus the number of capacitors is identical to the number of steps: six capacitors controlled by six steps.
Capacitors can be used for single, group, and central compensation. These types of compensation will be introduced in the following // In single compensation, the capacitors are directly connected to the terminals of the individual power consumers and switched on together with them via a common switching device.
Thus the number of capacitors is identical to the number of steps: six capacitors controlled by six steps. However, compensation banks with unequal steps, for example 50 kvar and 25 kvar (see Figure 1), enable compensation in ‘fine-stepping’ mode.
