The invention relates to the technical field of supercritical carbon dioxide power systems, and provides a supercritical carbon dioxide compression regenerative system which comprises a supercritical carbon dioxide compressor, a regenerator, a regenerator inlet regulating valve, a compressor driving motor, a plurality of densimeters, a plurality of pressure sensors and a data processing unit. And each densimeter and each pressure sensor are inserted into a heat regenerator working medium channel and are provided with measuring ends which are in direct contact with supercritical carbon dioxide fluid. The data processing unit receives signals transmitted by the densimeters and the pressure sensors through cables, accurately predicts the flowing and heat transfer performance of the heat regenerator according to a preset supercritical carbon dioxide physical property table, sends a rotating speed control signal to a compressor driving motor according to a prediction result, sends an opening degree control signal
