The invention discloses an intelligent acceptance device-based power distribution master station and an automatic joint debugging acceptance method of a terminal. The method comprises the steps of performing site configuration, communication parameter configuration and automatic acceptance planning template configuration; performing uniformization on clock of the power distribution master station,a power distribution terminal and an intelligent acceptance device, a power distribution equipment model and power distribution equipment model; controlling analogue quantity, state quantity and a protection signal which are generated by a power distribution terminal by the power distribution master station, and linking primary equipment; and recording measurement information and warning information which are received during the acceptance process in real time by the power distribution master station, matching with an acceptance rule, finding out an acceptance test item conforming to a condition, and generating an acceptance report. By the method, the labor cost and the communication cost are reduced, the working efficiency and the accuracy are improved, and standard power distribution acceptance operation is achieved.
