System power flow control method based on voltage phase adjustment of double-shaft excitation motor

The invention discloses a system power flow control method based on voltage phase adjustment of a double-shaft excitation motor. According to the technical scheme, a physical model based on a double-shaft excitation motor and a series transformer is established, so that the actual active power and the actual reactive power on a target line can change along with the change of d-shaft excitation current and q-shaft excitation current of the double-shaft excitation motor; a looped network power system model based on double-shaft excitation motor power flow control is established, the looped network power system model is operated, and operation parameter values of a looped network power system are measured; comparing the actual active power and the actual reactive power with the target active power and the target reactive power by giving the target active power and the target reactive power on the target line; and adjusting d-axis excitation current and q-axis excitation current of the double-axis excitation moto
