AB - The operation parameters and performance of a flash-binary power system are  analyzed based on four scenarios of the experiment (Exp), optimum design  (OD), error correction model 1 (ECM1) and error correction model 2 (ECM2).  The operation parameters of a flash-binary power system are tested to  explain steady in the experiment with heat source temperature ranges from  100°C to 150°C. The results show that the simulation data of error  correction model 2 have a good agreement with the experiment and most  parameter values of relative error δ are less than 5%. The expander with low  isotropic efficiency results in the largest exergy losses in the flashbinary  power system. The flash-binary power system has better performance to adapt  to the mid-high temperature geothermal resource in China. Some valuable data  obtained from the research can be applied in the future power plant  construction in China's southern Tibet, western Yunnan and Sichuan.
