Protective Measures against Waterhammer in Run of River Hydropower Plants

2012-10-01
Waterhammer is an unsteady hydraulic problem which is commonly found in the penstocks of hydropower plants, water distribution networks and pipeline systems. Due to either a malfunction of the system or inadequate operation conditions, pipeline may collapse or burst. In this paper protective measures against waterhammer problems in the penstocks of small hydropower plants are investigated. In the study, a computer program employing method of characteristics is used to solve nonlinear partial differential equations of transient flow. In a case study, waterhammer responses of a river hydropower plant under instant load rejection without a protective measure and with three different protective measures are analyzed. It is observed that, by means of protective measures waterhammer pressures in the penstock are substantially diminished, and it is shown that these measures are effective and practical.

Investigation of waterhammer problems in the penstocks of small hydropower plants
Çalamak, Melih; Bozkuş, Zafer; Department of Civil Engineering (2010)
Waterhammer is an unsteady hydraulic problem which is commonly found in closed conduits of hydropower plants, water distribution networks and liquid pipeline systems. Due to either a malfunction of the system or inadequate operation conditions, pipeline may collapse or burst erratically resulting in substantial damages, and human losses in some cases. In this thesis, time dependent flow situations in the penstocks of small hydropower plants are investigated. A software, HAMMER, that utilizes method of chara...
Comparison of Performance of Two Run-of-River Plants during Transient Conditions
Çalamak, Melih; Bozkuş, Zafer (American Society of Civil Engineers (ASCE), 2013-10-01)
Water hammer is an unsteady hydraulic problem commonly found in closed conduits of hydropower plants, water distribution networks, and liquid pipeline systems. Because of either a malfunction of a system or inadequate operation conditions, a pipeline may collapse or burst erratically, resulting in substantial damages and human loss in some cases. Therefore, it is crucial that engineers design and/or analyze projects with reliable computing methods for all foreseeable operation situations. In this paper, tra...
Computer Assisted Preliminary Design of Run-Of-River Plants
Alimoglu, Emir; Bozkuş, Zafer; Yanmaz, A. Melih (2014-10-01)
Run-of-river type hydroelectric power plants generate electrical energy by using a certain portion of the available flow in the river. In this study a computer program called MINI-HPD is developed to perform the hydraulic design of run-of-river plants. This program, which runs under the Windows operating system, is developed in C# programming language. MINI-HPD is capable of performing hydraulic design of structural components of diversion weir with lateral intake, overflow spillway, canal, forebay and pens...
