15 صفحه اولOverview of Steam Generator Tube-Inspection Technology
Degradation of steam generator (SG) tubing due to both mechanical and corrosion modes has resulted in extensive repairs and replacement of SGs around the world. The variety of degradation modes challenges the integrity of SG tubing and, therefore, the stations’ reliability. Inspection and monitoring aimed at timely detection and characterization of the degradation is a key element for ensuring ...
متن کاملAn Advanced State Estimation Method Using Virtual Meters
- Power system state estimation is a central component in energy management systems of power system. The goal of state estimation is to determine the system status and power flow of transmission lines. This paper presents an advanced state estimation algorithm based on weighted least square (WLS) criteria by introducing virtual meters. For each bus of network, except slack bus, a virtual meter...
متن کاملParticulate Fouling and its Effect on U-Tube Steam Generator Thermal Performance
A multiple-node SIMULINK model of a U-tube steam generator (UTSG) has been developed so as to simulate the UTSG dynamics or responses to various defects, including fouling. UTSG responses to different events, such as reduced heat transfer area, change in heat transfer coefficient at different axial nodes, change in tube material conductivity, and the change of steam valve coefficients have been...
متن کاملDevelopment of a Robust Model-Based Water Level Controller for U-Tube Steam Generator
Government or any agency thereof. The views and opinions of authors expressed herein do not necessarily state or reflect those of the United States Government or any agency thereof. SUMMARY Poor control of steam generator water level of a nuclear power plant may lead to frequent nuclear reactor shutdowns. These shutdowns are more common at low power where the plant exhibits strong non-minimum p...
