The invention relates to the technical field of energy sources, and discloses a solar power chemical recuperation gas turbine system. The solar power chemical recuperation gas turbine system comprises a tail gas reformer, a solar power reformer and a gas turbine with a combustion chamber and a gas turbine body, wherein the outlet in the reaction side of the tail gas reformer is connected with the inlet of the solar power reformer, the inlet in the smoke side of the tail gas reformer is connected with the gas discharge side of the gas turbine body, and the tail gas reformer is provided with a fuel inlet; the outlet side of the solar power reformer is connected with the inlet side of the combustion chamber; after the fuel burns in the combustion chamber, working is carried out in the gas turbine body, and generated tail gas enters the tail gas reformer; and the fuel enters the reaction side of the tail gas reformer through the fuel inlet after being mixed with water vapor, reform reaction is carried out under the heating action of the tail gas to generate synthesis gas, and the synthesis gas enters the solar power reformer and then further carries out reform reaction by absorbing concentrating solar power, and is supplied to the combustion chamber. With the solar power chemical recuperation gas turbine system, the energy utilization efficiency can be improved.
