The invention discloses a heat exchange system with a load regulating function. The heat exchange system with the load regulating function comprises a first high-temperature heat storage medium conveying pipeline, a preheater, an evaporator, a super heater, a water feeding device, a turbine and a second valve. Compared with the prior art, the heat exchange system with the load regulating function has the advantages that a ninth pipeline is provided with the second valve, the second valve can be opened when the load of the heat exchange system needs to be decreased so that a water working medium from the preheater can be shunted, one part of the water working medium enters the evaporator, the other part of the water working medium returns to the preheater, the amount of the water working medium entering the evaporator is made to be reduced, and accordingly the purpose of regulating the load of the heat exchange system is achieved.
