Claim 16:
17. A method for predicting power generation and remaining useful life for each system to predict operational soundness of a power plant, performed by a processor, the method comprising:
acquiring sensing data from each of a plurality of sensors included in a plurality of systems in the power plant;
calculating a predicted power generation and a predicted remaining useful life from a measurement value in sensing data of an input sensor through a pre-trained prediction model, and calculating prediction uncertainty in the corresponding prediction result;
assessing the operational soundness in aspect of the power generation using a prediction result and a current result in aspect of the power generation and assessing the operational soundness in aspect of the remaining useful life using a prediction result and a current result in aspect of the remaining useful life; and
determining the operational soundness of the system based on the prediction uncertainty and assessment results in aspect of the power generation and the remaining useful life, wherein assessing the operational soundness in aspect of the power generation for the corresponding system at a target time comprises:
calculating a power generation assessment index using a difference between a current power generation and the predicted power generation, and
determining a power generation assessment level from the power generation assessment index calculated using a preset range, and
wherein assessing the operational soundness in aspect of the remaining useful life for the corresponding system at the target time comprises determining a remaining useful life assessment level by comparing a current remaining useful life with the predicted remaining useful life.
