Frequency-Bias Tie-Line Control of Hydroelectric Generating Stations for Long Distances

In this work I have tried to apply effective dedicated online control systems to two equal power systems connected by a long distance tie-line. When large interconnected systems are linked electrically to others by means of tie-lines, the power transfers between them are usually decided by mutual agreement and the power is controlled by regulators. Other side it is a desired feature to achieve ...

Water Quality in Hydroelectric Sites

Hydroelectric pumped storage

Hydroelectric Pumped Storage (PHS) is the most widely utilised form of large-scale electrical energy storage (EES). The energy is stored as the potential energy of water raised against gravity. Water is pumped from a lower reservoir (1) to a higher reservoir (2), using the energy provided by the pumping unit (3), storing it as potential energy in the water. Figure 1 is a simple scheme of a PHS ...

Uncertainties of carbon emission from hydroelectric reservoirs

Anthropogenic greenhouse gas (GHG) emissions have substantially contributed to intensification of heavy precipitation and thus the risk of flood occurrence, and this anthropogenic climate change is now likely to continue for many centuries. Thus, precise quantification of human-induced GHG emissions is urgently required for modeling future global warming and precipitation changes, which is stro...

MICRO-HYDROELECTRIC PROJECT PHASE III Design Team

Phase III development of a micro-hydroelectric power generating system is focused on enhancing the system designed by Phases I and II. The previous phases focused on the use of the Gorlov Helical Turbine (GHT) to derive power from a fresh water environment, specifically the Stevens River in Vermont. Phase III exclusively focused on deriving power from an ocean environment and the construction o...
