The invention relates to a three-phase unbalance adjusting system parallel connection input system, a three-phase unbalance adjusting system parallel connection input control method, and a three-phase unbalance adjusting system parallel connection input control device. A main-three phase unbalance adjusting system is input in a power grid in a parallely-connected way, and at the same time, the system is used for real-time calculation of own actual power, and when the actual power of the three-phase unbalance adjusting system is greater than a set power threshold value, more than one slave-three phase unbalance adjusting system is input in the power grid in a parallely-connected way. The control strategies of the three-phase unbalance adjusting slave systems are input in a parallely-connected way are input according to the actual power condition of the three-phase unbalance adjusting main system, and three-phase unbalance adjusting requirements are satisfied, and therefore the rapid smooth adjusting of the thr
