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 ...

Abstract—This study presents a technique clarifying the effect of ambient air temperature and loads power factor changing from standard values on electric generator power rating. The study introduces an optimized technique for selecting the correct electric generator power rating for certain application and operating site ambient temperature. The de-rating factors due to the previous effects wi...

The implementation logic of different ISI items steam generator during the refueling outage nuclear power plant was studied. Based on relationship between window and main line plan outage, some optimization suggestions planning, preparation relevant were given, aimed at reducing inspection time SG collective dose inspectors.

Due to the complexity of detailed models, single-generator equivalent model (SEM) a wind farm is commonly used facilitate stability analysis. However, adequacy SEM for analysis in direct-drive farms with VSC-HVDC systems still uncertain. Therefore, this article analyzes two aspects: oscillation modes and sub-synchronous (SSO) enhancement by optimizing parameters. Firstly, various critical are c...

in this paper presents a maximum power point tracking (mppt) technique based on the hill climbing search (hcs) method and fuzzy logic system for wind turbines (wts) including of permanent magnet synchronous generator (pmsg) as generator. in the conventional hcs method the step size is constant, therefor both steady-state response and dynamic response of method cannot provide at the same time an...

Abstract The Superconducting Magnetic Energy Storage (SMES) device is gaining significance in utility applications, as it can handle high power values with a fast rate of exchanging energy at efficiency. large-scale invasion renewable systems into grid give rise to many integration issues. This SMES these issues due its various features. In this study the role tackling stability presence wind g...
