What is Synchronous condenser?

1 Answer

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.

•Synchronous condenser have slow speed of response.

Description : operating principle of condenser type microphone with neat diagram.

Answer : Principle: When sound pressure moves the diapharam in, the capacitance increases, and when it moves out, the capacitance decreases. The change in capacitance results in change in out put voltage of microphone. ... in volts.  Q= charge in coulombs  C= capacitance in farad Diagram: 

Description : Explain working of superheater and condenser. 

Answer : Working of Super heater:  Super heater consist of group of tubes. Tubes are heated by absorbing temperature of flue gases passed over it . Superheated steam' is meant that steam which ... condensate is reused in boiler. This type of condenser is used for high capacity thermal power plant. 

Description : State the function of cooling tower and condenser in thermal power station.

Answer : 1. Condenser:   Function of condenser is to convert exhaust steam again into water by reducing its temperature with the help of cold water. Also it reduces back pressure of steam turbine 2 ... tower : The function of cooling tower is to reduce the temperature of water coming from condenser.
