[ Abstract] 　The effective control on the voltage of double - feed generator stator is the key for the variable speed constant frequency generator
to realize the synchronized network without the impulse current. The author studies on the voltage control of the double feed generator stator,
compares and analyzes the mode for idle, on - load synchronized network and mode for " individual island" synchronization. He also gives the
advantages and disadvantages of allmodes.
