A system and a method for determine that performance of a helium turbine power generation system under an off-design condition belong to the field of data processing. Existing methods for determiningthe performance of power generation system under off-design conditions by using EXCEL form coordinate paper have the problems of hand-drawn standard curves, more human interference and large error, which lead to poor accuracy in determining the performance of power generation system under off-design conditions. The invention calculates the data read by the input module through the operation module, The standard curves which reflect the relationship between helium turbine flow rate, turbine inlet temperature, component efficiency, cycle total pressure ratio, efficiency optimum pressure ratio, surge margin, high/low pressure compressor inlet temperature and helium turbine power generation system performance under off-design conditions are plotted. Through the query module, the data read by the input module and the s
