Energy system equipment fault diagnosis method and system

The invention discloses an energy system equipment fault diagnosis method and system. The method comprises the following steps: acquiring performance parameters of equipment to be diagnosed; the to-be-diagnosed equipment is energy system equipment; inputting the performance parameters as input into the trained logistic regression model to obtain the fault confidence of the to-be-diagnosed equipment; and performing fault diagnosis on the to-be-diagnosed equipment based on the fault confidence. The technical problems of low working efficiency and long processing response time in the prior art are relieved. 本发明公开了一种能源系统设备故障诊断方法和系统，包括：获取待诊断设备的性能参数；待诊断设备为能源系统设备；将性能参数作为输入，输入到训练好的逻辑回归模型中，得到待诊断设备的故障置信度；基于故障置信度对待诊断设备进行故障诊断。本发明缓解了现有技术中存在的工作效率低和处理响应时间长的技术问题。
