摘要
Abstract
In a low-head run-of-river power station,flood season operations are frequently impacted by factors such as flood control level,reservoir flood control requirements,downstream pond backwater effects,and head loss caused by blockage of debris in front of the trash rack.Consequently,the units often operate below their rated head,leading to severe vibrations that can jeopardize the safety of fasteners and structural components.To ensure the safe operation of the units at the power station,an in-depth analysis of the operating stability at low head was conducted for Unit 5.Three characteristic heads were selected for on-site stability tests.The test data were analyzed to evaluate the unit's stability under low heads,identify vibration zones,and provide technical support for its low head operation.关键词
