## Abstract

The invention discloses a real-time calculation method for three-level over-limit safety risks of main steam pipeline pressure. The method comprises the following steps that whether kth-level over-pressure occurs or not is judged according to the kth-level over-pressure state SBk (ti-1) of each main steam pressure measuring point at the previous moment ti-1 and the kth-level over-pressure state SBk (ti) of each main steam pressure measuring point at the current moment ti; when the kth-level overpressure occurs, calculating the real-time overpressure safety risk value Rjk (ti) of each main steam pressure measuring point at the current moment ti according to the occurrence moment of the kth-level overpressure; according to the real-time overpressure safety risk value Rjk (ti) of each main steam pressure measuring point at the current moment ti, calculating an accumulated overpressure safety risk value Rj of each main steam pressure measuring point up to the calculation moment; and according to the accumulated overpressure safety risk value Rj of each main steam pressure measuring point up to the calculation moment, calculating the accumulated overpressure safety risk value R of the main steam pipeline up to the calculation moment. According to the method, the three-level overpressure safety risk of the pressure of the main steam pipeline is calculated in real time.
