摘要(Abstract):

水电机组在长期运行过程中累积了海量的稳定性状态监测数据,但其价值尚未得到充分利用。针对水电机组状态监测数据挖掘及运行工况识别,设计并搭建了用于水电机组振动区精细划分的工况样本数据库,提出了基于数据挖掘的水电机组振动区划分方法,实现对机组已运行工况稳定性分析及健康工况识别,达成振动区精细划分。实际应用表明,基于数据挖掘的振动区划分结果比经典振动区划分更加精确,对机组安全稳定运行具有重要的指导意义。
During the long-term operation of hydropower units, massive monitoring data of stability state are accumulated, but value is yet to be exploited. Given value mining of condition monitoring data of hydropower units and the identification of operating conditions of hydropower units, an operating condition sample database for the fine division of vibration region of hydropower units is designed and established and a vibra-tion zone division method based on data mining is proposed to analyze the operating condition stability recog-nize the healthy operating condition, and thereby fine division of vibration zone is completed. The application of the method shows that the aforementioned method is superior to that based on data mining in precision,providing a significant reference to operation safety and stability of units.
