The invention provides a backpressure unit circulating water energy-saving control system, a backpressure unit circulating water system and a control execution unit. The backpressure unit circulating water system comprises a steam turbine cylinder, a condenser, a cooling tower, a circulating water pipeline, a circulating water return pipeline and a circulating water pump. The steam turbine cylinder is connected with the condenser, a water outlet of the condenser is connected with a water inlet of the cooling tower through the circulating water pipeline, a water outlet of the cooling tower is connected with a water inlet of the condenser through the circulating water return pipeline, and a circulating water pump is arranged on the circulating water return pipeline. And the control execution unit is electrically connected with the steam turbine cylinder, the condenser and the cooling tower. And the control execution unit changes according to the change of the current operation condition and carries out adjustme
