AI Customer ServiceSuppress secondary arc with the installation of a neutral reactor, then allow for successful reclosing for transient line faults. Series capacitor bank is connected at the ends of or along the long EHV transmission line for the purpose of increasing power transfer capacity by compensating the line series inductance .
Assuming two identical series capacitor banks are installed at the one-third and two-third of the line, which can provide 60% compensation in total. The reactance of one capacitor is -j34.96 Ω. A simple example is given below to show the voltage profile along the line at the heavy load condition with and without series compensation.
Instead of using a single unit of capacitor per phase of the system, it is quite effective to use a bank of capacitor units, in the view of maintenance and erection. This group or bank of capacitor units is known as capacitor bank. There are mainly two categories of capacitor bank according to their connection arrangements. Shunt capacitor.
The capacitor banks may be applied grounded or ungrounded. There are many shunt capacitor bank designs and methods of protection that are applied at all sub-transmission and transmission voltage levels up to 765 kV. The application and protection of shunt capacitor banks are discussed in References 2 and 3.
The capacitor reactance is generally applied to the system by using static capacitor in shut or series with system. Instead of using a single unit of capacitor per phase of the system, it is quite effective to use a bank of capacitor units, in the view of maintenance and erection. This group or bank of capacitor units is known as capacitor bank.
