<p>PURPOSE:To facilitate the judgment of a plant state by providing an operator with the generating state of an alarm in the case of generating an abnormality, and judging and displaying an important information according to the plant state. CONSTITUTION:When a turbine trip abnormality occurs, for example, and an alarm signal 4a is generated, the matching with the important alarm data of an important alarm storing part 2 is conducted in an important alarm judging part 1, and when it is registered as an important alarm such as a nuclear reactor automatic scram, the nuclear reactor automatic scram is displayed on an important information display part 3. Thus, an operator can know the generation of the nuclear reactor automatic scram alarm. In an information selecting part 5, the information related to the generated alarm is read from a data base 6, and on the basis of this information, the adaptability of the alarm generation, the judgment of a first generated alarm, the prediction of an alarm to be generated thereafter, and the judgment of the abnormality cause are conducted by using knowledge processing, and the results are displayed on a display part 3.</p> |
