Why capacitor bank does not require in DG Set?
Answer Posted / prashant pandey
Total power KVA is the square root of the sum total of the squares of active power (KW) and reactive power (KVAR). Here the active power is VICos$ which is the actual useful power whereas the reactive power is the imaginary power or wastage in lay man's terms. Cos$ is the power factor, which should be ideally equal to 1 for minimum wastage of power and maximum useful power.
In Inductive circuits, Current tends to lag the voltage whereas in capicitive circuits it tends to lead the voltage. In case we have a lot of inductive load on the DG sets, capacitor bank to balance the inductive load so that the PF is as close to 1 as possible will be definitely useful. It has been practilly observed that the total load ampere of the DG reduces resulting in better utilization of DG capacity. In absence of inductive load, capacitor bank will not be required. Capacitor bank is to be used only to the extent of balancing the inductive load, for better utilization of the DG set.
