Difference Between Series And Shunt Compensation. Shunt compensation improves power factor of the system whereas in series compensation the stability and voltage profile in case of medium and long lines mostly is improved. Series devices have developed from mechanically or fixed switched compensations to the voltage source converter based devices. Jadhav PhD Professor Electrical Dept. RIT Rajaramnagar Power Flow through a Transmission Line Complex Power on per phase basis Mid point shunt compensation Series Compensation Remarks A line with 100 series compensation would have a resonant frequency equal to power frequency.
Series and Shunt Compensation 2. At the buses where reactive power demand increases the bus voltage is controlled by connecting capacitor banks in parallel to lagging load. Compensation of long lines. There are different technologies for reactive power compensation these includes. Shunt compensation improves power factor of load whereas series compensation has very little effect on load power factor. RIT Rajaramnagar Power Flow through a Transmission Line Complex Power on per phase basis Mid point shunt compensation Series Compensation Remarks A line with 100 series compensation would have a resonant frequency equal to power frequency.
Shunt compensation will be able to change the power flow in the system during and following dynamic disturbances so as to increase the transient stability limit and provide effective power oscillation damping.
In other words in series compensation reactive power is inserted in series with the transmission line for improving the impedance of the system. The static synchronous series compensator SSSC and thyristor-controlled series capacitor TCSC are some of the FACTS control devices which provide series compensation to reactance of the lines to which they are connected while the static synchronous compensator STATCOM and static VAR compensator SVC where VAR stands for voltampere reactive are FACTS devices which provide shunt compensation. In other words in series compensation reactive power is inserted in series with the transmission line for improving the impedance of the system. The potential effectiveness of shunt a s well as other compensation and flow control. Advantages of Series Compensation 1. It consists of capacitors connected in series with the line at suitable locations.
