Description The use of series capacitors in long distance Extra High Voltage (EHV) Transmission has become very common, since it offers an effective economical means of improving stability limits the transmission lines that are capable of carrying large blocks of power over long distances. They are also highly valuable in other respects such as voltage regulation, reactive power balance, load distribution etc. while the shunt reactors improve the voltage control facilitate lineenergisation and reduce temporary transient over voltages. Due to practical economical reasons, the compensating elements are located at few points along the line instead of being distributed over the entire length of the line location, circuit schematic of series capacitor shunt reactor stations are the deciding factors for maximum power transfer capability, voltage control conditions efficiency of power transmission of the compensated transmission system. Due to above considerations, in the present work various schemes of series shunt compensation are considered for investigation. The analytical expressions for maximum load end power for various schemes are derived in terms of capacitive reactance used, sending end and load end voltages, and generalized line constants. The optimum value of compensation for each scheme has been determined. In the present study, an analytical approach is presented for comparative study of series and shunt compensation schemes of long transmission lines connected to the large load area based on maximum power transfer capability for the voltage stability consideration.
