AI Customer ServiceAbstract: A centralized reactive power compensation system is proposed for low voltage (LV) distribution networks. It can be connected with any bus which needs reactive power. The current industry practice is to locally install reactive power compensation system to maintain the local bus voltage and power factor.
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.
The compensation capacitor Cc plays the main role in the frequency response of the Operational Amplifier. The return pin of Cc should be grounded, if there is such a pin and the op amp is not grounded. In this case, the capacitor current will return to one or two power supplies. (Figure 1. Block Diagram of a Non-Rail-to-Rail Amplifier)
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.
