Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0026] A power flow control device includes a synchronous motor M, a synchronous motor G, and a series transformer; the synchronous motor M is connected in parallel to the low-voltage side of a substation transformer, the synchronous motor G is connected to the primary side of the series transformer, and the secondary side of the series transformer is connected to the high-voltage side of the substation transformer.
[0027] Synchronous motor M and synchronous motor G are two coaxial synchronous motors whose magnetic field windings differ by 90 electrical angles. One is used as a motor and the other is used as a generator. Motors with conventional field control.
[0028] The capacity of the syn...
