HVAC 3-PHASE CAPACITOR BANKS Designing capacitor banks starts with basic information collection with respect to facility and immediate utility network characteristics. Network rated voltage, operating voltage, frequency, and short circuit availability are necessary for proper capacitor bank design.
Continued from part two – Capacitor Banks In Power System (part two) Capacitor units shall be suitable for continuous operation at an RMS current of 1.30 times the current that occurs at rated sinusoidal voltage and rated frequency, excluding transients.
The system can be designed as a fixed or switched capacitor bank. The capacitor banks consist of either single-phase or three-phase capacitor units suitably designed and connected in order to meet the total amount of reactive power required at the specified frequency and voltage.
When a capacitor bank is initially connected to a voltage source, transient charging current will flow, attempting to equalize the system voltage and the capacitor voltage. If the two voltages are equal at the time of switching, no inrush current flows.
The bank requires the use of 12 units per phase and 36 total units, which results in rated unit kvar of 24000/36=667 kvar. • Single wye option: two series sections with six parallel-connected units per series section. Each phase consists of 12 units or 36 units for a three-phase bank. Each unit should be rated 9.96 kV and 667 kvar.
In accordance with IEC 60871-1, the inrush current should be limited within 100 times the rated current of the capacitor bank. When a capacitor bank is initially connected to a voltage source, transient charging current will flow, attempting to equalize the system voltage and the capacitor voltage.
