Synchronous
condenser
•Big advantage of synchronous condenser is their large temporary overload
capability and good harmonics performance.
•Synchronous
condenser is a
synchronous machine which is use to generate or absorb reactive power.
•When
it is absorbing power it acts like inductor and when it is generating power it acts like capacitor.
•When absorbing power it is underexcited and when generating power it is overexcited.
•Its
reactive power output can be control by varying excitation current.
•It is
use for shunt reactive power compensation and to improve the stability of the system and to
maintain the voltage at desired limits.
•It is a type of active shunt compensation device.
•Machine
generated voltage and system voltage is equal.
•Synchronous
condenser is
connected to power system via coupling
transformer.
•Due
to continuous operation machine gets heated so hydrogen cooling is use for cooling the condenser.
•Synchronous
condenser are
more expensive than static compensator.
•Synchronous
condenser is
use at HVDC terminals.
•Synchronous
condenser is
use at both transmission and distribution voltage levels.
