Abstract

Abstract

In order to improve the intelligent operation and maintenance level of nuclear power plants, and effectively prevent and reduce equipment downtime, this paper designs and develops an intelligent monitoring and prognosis system for reactor coolant pumps (RCPs). The system integrates data acquisition and storage, online monitoring, fault diagnosis, trend prediction, fault treatment measures and prevention decision support. The verification results show that the system can track the running status of the RCP in real-time. Under fault conditions, the abnormal information of the RCP can be detected timely, and the fault mode is identified accurately. Then the O&M guidance is provided based on the current equipment status and parameter trend prediction results. Therefore, the system can track and identify the running state of reactor coolant pump in time to achieve the purpose of improving the condition monitoring capabilities and intelligent O&M level of nuclear power equipment.
