Title:
INTELLIGENT MONITORING METHOD AND SYSTEM FOR NUCLEAR POWER STATION STEAM GENERATOR
Document Type and Number:
WIPO Patent Application WO/2024/061196
Kind Code:
A1
Abstract:
The present invention provides an intelligent monitoring method and system for a nuclear power station steam generator. The system comprises a device thermal performance monitoring module, a device flow field digital twin module, a heat transfer tube flow-induced vibration monitoring module, a heat transfer tube wearing monitoring module, a device fatigue damage monitoring module, a device loosened component monitoring module, and a monitoring data and file management module, can be used for thermal performance monitoring, local flow field monitoring, heat transfer tube flow-induced vibration and wearing evaluation, and fatigue and loosened component monitoring and diagnosis of the steam generator, and is used for full life cycle management of the steam generator; in an installation process of the system, no new sensor is added, so that the installation is simpler and more convenient. Moreover, the system can monitor data such as a dirt coefficient and a flow field distribution condition which cannot be monitored, and predict the wearing condition of the heat transfer tube, so that the time required for maintenance of the steam generator is greatly shortened, and the economic benefit of a nuclear power station is improved.
