NRI <strong>Annual</strong> Research <strong>Report</strong> <strong>2001</strong>-<strong>2002</strong>Project Title:Technical and Economical Evaluation of Flow Control Methodsfor Power Plant ElectropumpsBoilersDepartment: Power PlantElectric SystemsProject Manager: E. SadeghianContractor: Niroo ResearchInstituteProject Code: ---Project Staff: G. Gharehpetian, H. RamezanzadehSummary:The Flow of air and steam are changed for different output generation of Power Plants.There are various methods to control the electropumps such as Valves control method,Bypass valves application, Hydroulic turbo coupling usage and Adjustable SpeedDrives (ASD). Dampers, Inlet guide vanes, variable speed axial and ASD are the maintools of control for fans. In this project, the above mentioned flow control methods areevaluated and compared from technical and economical point of view.−Project Results:One of the best technical and economical solution for flow control is ACAdjustable Speed Drives. The main advantages of ASD are the minimization ofelectric energy consumption, elimination of throttling and bypass valve, and lowermechanical stress on equipment, etc.Project Documentation:Power Plant Electric Systems Department; <strong>Report</strong> of “Technical andEconomical Evaluation of Power Plant Pump Flow Control Methods”; PowerGeneration Research Center; NRI; Summer <strong>2001</strong>.22
