Objectives
of shunt compensation
•Shunt
compensation is use to improve
power factor.
•In Shunt compensation FACTS are connected in parallel
with power system and works like a controllable current source.
•There
are two
types of
shunt compensation.
•If
the inductive load is connected the lagging load current flows to compensate
this shunt
capacitor is
used.
•And
if the capacitive load is connected the leading load current flows to compensate
this shunt
inductor is
use.
•If
the power system is lightly loaded then fixed or switched shunt reactor is use for maintaining voltage
level.
•And
if the power system is heavily loaded then fixed or switched shunt capacitor is use for maintaining voltage
level.
•The
objective of using shunt compensator is to increase the transmittable power, Increase transient stability, Increase system stability, reduce loss.
•VAR
compensator is
use for voltage regulation, Dynamic voltage control and damp power oscillation.
•Examples
of shunt compensation is STATCOM and SVC.
