The invention discloses a method, a system, equipment and a medium for determining a hydrodynamic phase change point of a boiler, and the method comprises the following steps: responding to a received phase change point determination request, dividing a water-cooled wall tube of the boiler under supercritical pressure into a plurality of tube sections according to a preset grid interval, and determining the tube section where a wall tube inlet of the water-cooled wall tube is located as a first tube section, according to a comparison result between a difference value between a working medium temperature and a quasi-critical temperature corresponding to an inlet and an outlet of a first pipe section and zero, after it is determined that a hydrodynamic phase change point exists in the first pipe section, the phase change point of the boiler water wall pipe is determined according to a comparison result between an absolute value of the difference value and a preset temperature deviation value.
