The invention relates to a nuclear power device state monitoring method and system. The method comprises the following steps: firstly carrying out sampling and optimization on an original training set, obtaining an optimized data set, not reducing the data quality while reducing the data dimension, and selecting steady-state data, thereby guaranteeing the quantity basis of the data; training a statistical analysis model based on the optimized data set to obtain a trained statistical analysis model; inputting a real-time data set into the trained statistical analysis model to obtain a state of a nuclear power device. According to the invention, states of a nuclear power device can be effectively monitored in real time, the performance requirements for a processor are reduced, and false alarms are decreased. 本发明涉及一种核动力装置状态监测方法及系统，首先对原始训练集进行抽样和优化得到优化数据集，在降低数据维度的同时不降低数据质量，并且选择稳态数据，保证了数据的数量基础；基于所述优化数据集对统计分析模型进行训练，得到训练好的所述统计分析模型；将实时数据集输入训练好的所述统计分析模型，得到核动力装置的状态。本发明可以实时有效地对核动力装置的状态进行监测，降低了对处理器的性能需求，减少误报警的发生。
