Experience in operating the units of the Zeya hydroelectric station with diagonal-flow turbines
Conclusions Large hydrostations should have their own vibration diagnostics services for checking the main and auxiliary equipment. The quality of installing units must be determined from the results of a complete set of vibration tests, and these tests should be conducted regularly during the operating period. The volume of repairs of the main and auxiliary equipment of hydrostations should be corrected with consideration of their vibration characteristics.When regrading units toward an increase of installed capacity, it is necessary to check the control guarantee upon dumping the load and the effectiveness of the excitation systems with short-circuiting at the buses. For the Zeya hydrostation, the limiting value of increasing the capacity with respect to the indicated parameters was 5%.The service life of a welded-type runner pit of a diagonal-flow adjustable-blade turbine is affected not only by the presence of cavities in the space behind the lining of the pit but also by the operation of the turbine in a propeller regime at the start-up heads.
