Define Shunt VAr Compensation?
Shunt capacitors absorb leading VArs (i.e. they are used to supply lagging VArs) whereas reactors are used to absorbs lagging VArs. Capacitors and reactors can be either directly connected to the busbar (fixed) or connected through switches (mechanical or thyristors). In the latter, the number of elements connected to the system may be controlled in order to supply the required VAr demand to maintain a specified value of the voltage.
Equation shows that the voltage at the mid-point of a transmission line can be maintained constant by using a dynamic shunt VAr compensator connected at this point.
ΔV / VR = 1/SCL [(R/X) P + (Q-QC)]
This means that the line is sectioned into two "independent" equal halves. Thus, assuming that VS = VR = Vm (mid-point voltage) = V, the power equation for each half, using equation
P = ((VS VR) /X) sin δ
may be written as:
