Claim:
1. A method for monitoring a cold start of a Brayton cycle power generation system, the Brayton cycle power generation system comprising a working fluid, the method comprising the following steps: measuring an ambient temperature of the Brayton cycle power generation system, to obtain a Brayton cycle predetermined operating line of the working fluid, initial values and default values of parameter values and calculated values of at least 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 look up table (LUT); starting the cold start of the Brayton cycle power generation system, 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, wherein the moving trajectories move from the initial values of the parameter values and the calculated values of the three monitoring points to the default values 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 after the Brayton cycle power generation system has been operated for the predetermined time, ending the cold start of the Brayton cycle power generation system, to enter a stable operating state of the Brayton cycle power generation system.
