Suppose a synchronous generator is synchronized with the
grid. This generator will work as synchronous condenser if we
over excite the rotor i.e the generator will supply reactive
power also to the grid. If we dont require the generator to
supply active power, the steam in put(for Thermal machines)or
water input (hydro generators) can be stopped. The machine
will continue running as synchronous condenser mode supplying
reactive power but consuming some active power, from the grid,
required for the rotation of the machine.
