By taking the test bench of a micro gas turbine cycle system as the research object, a mathematical model for regenerative cycle system of the micro gas turbine is established. On this basis, the performance prediction and analysis for the regenerative cycle system is carried out. Considering the performance parameters of the system’s key components are presently unknown, the maximum likelihood estimation method is employed to estimate them by using the experimental data. The results show that, the error between the model predicted value and the experimental value is smaller than 3%, indicating the model can accurately predict the thermal performance of the cycle. Subsequently, based on the established model, a performance simulation of the recuperative cycle is conducted under various working conditions. The variation rules of power, generation efficiency, exhaust gas energy, and exhaust gas temperature with the changes of load and ambient temperature are obtained, and the compressor’s operating range is also obtained. The information regarding the key components of the microturbine and the performance characteristics acquired through this study can serve as valuable references for related research.
