Hybrid Pump Storage Hydro Power Plant: Site Selection, Economic Analysis and Water Hammer Calculation(PPT)

摘要

1. Licence from PPC, Concept works with: 1.1. 2 Pelton, each 2.5 MW, 1.2. 4-10 Pumps, more pumps better for start up but more expensive, 1.3. Total 5.1 MW pumping power, 1.4. Concept fullfill also the requested cycle efficiency. 2. Water hammer calculations show that a system without surge tank or air vessel is possible. 3. Additional flywheel mass for the pump system is necessary to avoid cavitation. 4. For all scenarios without hydraulic shortcut for the GRP-Pipe PN40 and for steel pipes and valves (pumps, turbines …) PN63 is sufficient.
