Abstract
A synchronous condenser has a rotor, a rotor shaft on which the rotor is mounted, and collector rings electrically connected to a source of D.C. voltage. A fluid drive has an output shaft connected to the synchronous condenser rotor shaft through a quick disconnect mechanism, an input shaft, and a motor connected to drive the input shaft. In bringing the synchronous condenser onto line, the speed of rotation of the output shaft of the fluid drive is brought to a speed slightly greater than the synchronous speed, a D.C. voltage is applied to the collector rings of the rotating field to generate a polyphase A.C. voltage in the windings in the stator core, and the polyphase breaker is closed just as the phases are brought into synchronization with the corresponding phases of the power grid. After the synchronization is complete, the disconnect coupling is operated to separate the starting mechanism and the starting mechanism is shut down. The entire process can be accomplished by remote control.
