In electrical engineering, a synchronous condenser, also called as synchronous compensator or a synchronous capacitor is a DC-excited synchronous motor, and its shaft is does not interconnected with anything but get spin easily. It does not intend to work as converting the electric power to mechanical power or vice versa, but to regulate settings on the electric power transmission grid. Its arena is controlled by a voltage regulator for generating or absorbing reactive power which is required to modify the voltage of grid or to enhance the power factor. The condenser’s operations and installation are similar to large generators and motors.
The induction motor and synchronous motor are frequently used types of AC motor. They both can be differentiated as follow: the synchronous motor rotates at a rate restricted to the line frequency meanwhile it does not depend on present generation to produce the rotor’s magnetic field. On the other hand, induction motor which is also called as asynchronous motor needs slip (Slip, s is defined as the difference between operating speed and synchronous speed): where the rotor must rotate little bit slower than the AC rotations for inducing current within the rotor winding. Small sized synchronous motors are utilized in timing applications including appliances such as timers, synchronous clocks, tape recorders and precision servomechanisms in which operating speed of the motor should be precise and accurate speed of the power line frequency, which needs to cautiously controlled in large interconnected grid systems.
Increasing electric power consumption and growing necessity to increase transmission capacity are some major aspects fueling the demand for synchronous condenser globally. Growing number of power plants in developed as well as developing countries is another aspect propelling the demand for synchronous condenser. In addition, in some existing plants are creating demand for synchronous condenser in order to improve the power generation process, which may fuel growth of the synchronous condenser market.

However, high cost of equipment and its maintenance are some major aspects affecting on the demand for synchronous condenser globally.
The type of synchronous condenser can be defined as <100 M Var, 100-200 M Var, and >200 M Var. The >200 M Var synchronous condenser are high in demand due to increasing necessity for power factor correction. In addition, increasing demand for reactive power in for stabilizing the grid and maintaining the voltage regulation is fueling the demand for 200 M Var synchronous condenser.
The application of synchronous condenser includes hydrogen, air, and water. Hydrogen is becoming popular among other applications, which can be attributed to its most preferred cooling method deployed for medium- to large-sized synchronous condensers. In addition, one of the key driving factor will be installation of hydrogen-cooled synchronous condenser units between 100 and 300 M Var globally.
North America dominates the synchronous condenser market. This can be attributed to increasing number of new power plants as well as increasing application of synchronous condenser in existing power plants across the region. Rising demand for synchronous condenser in Asia Pacific can be attributable to increasing renewable power generation activities.
Major players operating in the global market are Siemens, GE, Eaton, ABB, Voith, and WEG.
