Reactor-following load adjusting method and system for nuclear energy heat supply unit

The invention relates to a nuclear energy heat supply unit reactor following machine load adjusting method and system. The nuclear energy heat supply unit reactor following machine load adjusting method comprises the steps that a heat supply unit steam turbine first-stage pressure signal and a steam extraction heat supply flow signal are collected; the collected signals are preprocessed, and the load value of the steam turbine is determined based on the processed signals; and the reactor power of the heat supply unit is adjusted based on the steam turbine load value. According to the technical scheme provided by the invention, the problem of large deviation between the reactor power and the steam turbine load value in the unit heat supply operation process of a conventional logic loop is solved, the control accuracy is improved, and meanwhile, the system disturbance caused by potential curve switching manual operation errors during multi-curve mode operation is also solved; the fluctuation of the operation pa
