The invention relates to the field of power system control, in particular to a method for coordinated control of AVC and PSVR. The present invention provides an AVC and PSVR coordinated control methodin response to problems such as slow response voltage, long time consuming, and inability to improve system transient stability of the existing automatic voltage control system. In the control method, the absolute value of the difference between the system voltage target value issued by the AVC main station and the measured value of the main transformer high voltage side bus voltage is compared with the preset setting value, the PSVR system is selected for operation according to the comparison result, the generator terminal voltage reference value is adjusted by the analog adjustment mode, orthe shutting is selected to quit the PSVR system operation, and the generator terminal voltage reference value is adjusted by the mode of increasing or decreasing magnetic pulses. The control methodof the invention can collec
