1. 1. Sustainable Production Patterns for Hydropower Units

   University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Author : Hannington Kayanja; [2023]
   Keywords : Automatic control; Hydropower modelling; PD-controller; Sustainable power production; Water level control.;

   Abstract : Globally, a significant portion of energy comes from hydropower. However, harnessing hydro energy interrupts the natural state of river flows, thus affecting the ecological processes of the surrounding communities. READ MORE

3. 2. Efficiency Analysis of a Wave Energy Converter Penstock

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Péter László Bondár; Felix Myrsten; [2021]
   Keywords : Efficiency Analysis; Machine Design; Optimisation; Penstock; Wave Energy Converter; Effektivitetsanalys; Maskinkonstruktion; Optimering; Tilloppstub; Vågkraftverk;

   Abstract : Novige develops a wave energy converter (WEC) concept that utilizes wind-generated wave to create electricity. The system uses a float and a hydraulic cylinder to pump water up to a turbine, similar to an inverted hydro power plant. READ MORE

4. 3. Techniques to inject pulsating momentum

   University essay from Luleå tekniska universitet/Strömningslära och experimentell mekanik

   Author : Jelle Kranenbarg; [2020]
   Keywords : Hydro power; Rotating Vortex Rope; Flow control; Fluidic actuator; Synthetic jet actuator; Piston actuator; CFD;

   Abstract : Hydro power plants are an essential part of the infrastructure in Sweden as they stand for a large amount of the produced electricity and are used to regulate supply and demand on the electricity grid. Other renewable energy sources, such as wind and solar power, have become more popular as they contribute to a fossil free society. READ MORE

5. 4. Conjunctive Operation of Hydro and Solar PV Power with Pumped Storage at Kafue Gorge Power Station (Zambia)

   University essay from Högskolan Dalarna/Energiteknik

   Author : Elvis Nyirenda; [2019]
   Keywords : Photovoltaic; Hydro; Power; Storage; Pumped Hydro Storage; Zambia;

   Abstract : This report covers the work carried out to redesign the two existing conventional hydro power stations in Zambia on the Kafue river into the pumped storage facility with solar photovoltaic power so that security of supply and water conservation is achieved to reduce the power deficits during the dry and drought periods. The two stations are Kafue gorge upper power station (KGUPS) and Kafue gorge lower power station (KGLPS) with an installed capacity of 990 MW and 750 MW respectively. READ MORE

6. 5. Preliminary simulation of Porjus U9 turbine at speed no load

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Henrik Holmström; [2019]
   Keywords : Kaplan; Speed no-load; SNL;

   Abstract : Hydropower plants are shifting towards operating at off-designed conditions, meaning that the number of start-stop cycles and maintenance time due to cavitation increases. The speed no-load condition is the moment before magnetization of the generator, i.e., no load, low flow, constant runner rotational speed, guide vane and runner blade angle. READ MORE
