Therefore, the use of capacitor banks in any of their versions (single-phase, three-phase, scalable battery, SVC, etc.) is the most economical and sufficient solution. In this study, a calculation algorithm is proposed to obtain compensators for the inductive reactive power of the load, consisting only of single-phase capacitor banks.
The capacitances of single-phase compensation banks can be calculated using (47). Under these conditions, new currents circulating through the lines feeding the set formed by the load and compensation equipment, were calculated. The values are presented in Table 4.
For this reason, double star connection is preferable. Go back to Content Table ↑ This type of wiring is suitable for all powers and all voltages of capacitors. It retains the advantages of star connection, and adds a protection mode enabling internal faults to be detected.
Compensation capacitors are installed in numerous locations in electrical installations. They are to be found in high voltage transmission and distribution systems, in transformer substations and also at various levels in low voltage installations.
1. Connections of capacitor banks This is the most commonly used connection mode for capacitor banks with voltages lower than 12 kV. This configuration, which is used in particular in distribution installations, provides maximum reactive power in minimum dimensions.
Considering power capacitor with rated power of 20 kvar and 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 capacitor. Once we know the total reactive power of the capacitors, we can choose series of capacitors for PF correction.
