The aim of the project was to design a capacitor bank with reactive power compensation. The panel was to be power capacitor based with automatic control by power factor regulator, rated at 200kVar and 400V, and adapted for operation with mains where higher order harmonics are present.
For example, the configuration for a 5-stage capacitor bank with a 170 KVAR maximum reactive power rating could be 1:1:1:1:1, meaning 5*34 KVAR or 1:2:2:4:8 with 1 as 10 KVAR. The stepping of stages and their number is set according to how much reactive power changes in a system.
Power capacitors are rated by the amount of reactive power they can generate. The rating used for the power of capacitors is KVAR. Since the SI unit for a capacitor is farad, an equation is used to convert from the capacitance in farad to equivalent reactive power in KVAR.
There is a novel method to actively compensate for the reactive current caused by the EMI capacitor. Moreover, the PFC current-loop reference is reshaped at the AC zero-crossing to accommodate for the fact that any reverse current will be blocked by the diode bridge. Both PF and THD are improved as a result. Figure 3.
Reactive power is either generated or consumed in almost every component of the system. Reactive power compensation is defined as the management of reactive power to improve the performance of AC systems. Why reactive power compensation is required? 1. To maintain the voltage profile 2. To reduce the equipment loading 3. To reduce the losses 4.
Once we know the total reactive power of the capacitors, we can choose a series of capacitors for power factor correction. Considering a power capacitor with a rated power of 20 kvar and a rated voltage of 440V supplied by mains at Un=400V. This type of calculation is true if there is no reactor connected in series with the capacitor.
