Abstract: A method for monitoring cold start of Brayton cycle power generation system comprises: measuring an ambient temperature to obtain a Brayton cycle predetermined operating line of a working fluid, parameter values and calculated values of three monitoring points of the Brayton cycle predetermined operating line, and a position of a saturation curve of the working fluid according to the ambient temperature and a LUT; starting the cold start, continuously measuring the parameter values of the three monitoring points, and meanwhile continuously recording and displaying moving trajectories of the parameter values and the calculated values of the three monitoring points; after the parameter values and the calculated values of the three monitoring points are close to the default values, operating the Brayton cycle power generation system for a predetermined time; and ending the cold start, to enter a stable operating state of the Brayton cycle power generation system.
