Unlike a static condenser (capacitor bank), the value of reactive power from a synchronous condenser can be continuously adjusted.
A synchronous condenser also has other advantages over static condensers such as:
- not being affecting by harmonics (some harmonics can even be absorbed by a synch condenser)
- producing no switching transients

If a motor is spinning under no load, it is storing some energy in the rotating mass. This energy can be stored and released in the same way capacitors and inductors store and release energy. This is what a synchronous motor acting like a condenser is doing. The way it appears to the power system is dependent upon the field current applied to it. If used as a motor, this is controlled to keep it spinning at the desired speed under load. If used as a condenser, it is controlled to determine whether it will be releasing power ahead of or behind the power system (absorbing or releasing VARs).
ASYNCHRONOUS is a mode whereby events happens irregardless of control. SYNCHRONOUS are this same events but controlled by a timing and/or control
Yes, but overloads cannot differ by return type alone. The signatures must differ by the number and/or the type of the arguments.
synchronous input means that the flipflop reads input only at posedge or negedge of the clock.
Slip, , is defined as the difference between synchronous speed and operating speed, at the same frequency, expressed in rpm or in percent or ratio of synchronous speed. Thus
