Load and distributed generation characteristics have both changed to require increased VAR support throughout the power system. Substation capacitor banks are the most economical form of adding VARs to the system, yet because of harmonics, grounding, and operational concerns, there are many different types of capacitor banks.
In the tie lines, the power transfer capability is significantly increased if the series compensation is applied. Beside usage of series capacitors in power distribution systems, they are used in many applications where the load is fluctuating in nature.
In this section, we delve into a practical case study involving the selection and calculation of a capacitor bank situated within a 132 by 11 KV substation. The primary objective of this capacitor bank is to enhance the power factor of a factory.
Because series capacitors are installed in series on a transmission line, the equipment must be elevated on a platform at system voltage, fully insulated from ground . The capacitor bank together with the overvoltage protection circuits are located on this steel platform.
In a transmission system, the maximum active power transferable over a certain power line is inversely proportional to the series reactance of the line. Thus, by compensating the series reactance to a certain degree, using a series capacitor, an electrically shorter line is realized and higher active power transfer is achieved.
The principle of operation behind this protection system involves the instantaneous operation of the spark gap whenever the voltage across the spark gap exceeds the predetermined safe value. Thus, the series capacitor voltages are maintained within acceptable value.
