Regenerative thermodynamic power generation cycle systems, and methods for operating thereof

A regenerative closed loop thermodynamic power generation, cycle system is presented. The system includes a high-pressure expander to deliver an exhaust stream. A conduit is fluidly coupled to the high-pressure expander, which is configured to split the exhaust stream from the high-pressure expander into a first exhaust stream and a second exhaust stream. The system further includes a first low- pressure expander and a second tow-pressure expander. The first low-pressure expander is coupled to a pressurization device through a turbocompressor shaft, and fluidly coupled to receive the first exhaust stream. The second low-pressure expander is coupled to the high -pressure expander and an electrical generator through a turbogenerator shaft, and fluidly coupled to receive the second exhaust stream. A. method for operating the regenerative closed loop thermodynamic power generation cycle system is also presented
