The use of a monitoring system, designed to monitor the condition of hydroelectric plants from the vibrational, mechanical and magnetic characteristics under different operating conditions, is considered. The results of a comparative analysis of similar and different types of plants, obtained using the "ALMAZ-7010-GÉS" steady monitoring and diagnostics system and new sensors developed by the "DIAMECH 2000" Company, are presented.
Experience of operation of a K-800-240-5 turbine of the Berezovskaya State Regional Power Plant-1 is used for considering the problems of reliability of low-pressure cylinders (LPC), their interaction with condenser, and vibration instability due to heat-induced deformations of supports. Experimental data for the "LPC -condenser" system obtained under field conditions are presented. Suggestions on improving the structure and the operating process of LPC of K-800-240-5 turbines are made.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
