Self-adaption Technology for Abnormal Operation of Pumped Storage Power Station

It is difficult to find the defects of abnormal operation sequence or jitter of monitoring signals in the operation and maintenance of Large Pumped Storage Power Plant. With the development of this hidden defect, the main equipment may be shut down. In this paper, the adaptive diagnosis technology of pumped storage power plant equipment change is proposed, which can be used as the supplement of computer monitoring system. It can generate error code and output alarm adapt by means of automatic detection and control. It provides technical support for the operation and maintenance personnel to quickly locate the defective equipment and find the defect characterization. In addition, the standard inspection and maintenance methods for monitoring signal jitter and abnormal equipment action sequence of the equipment to which the monitoring signal belongs are also provided, which provides an effective technical means for rapid processing of defects characterized by multiple equipment action sequence abnormalities and monitoring signal jitter.
