We conduct a benefit-cost analysis of a relicensing agreement for two hydroelectric dams in Michigan. The agreement changed daily conditions from peaking to run-of-river flows. We consider three categories of costs and benefits: producer costs of adapting electricity production to the new time profile of hydroelectric output; benefits of reductions in air pollution and greenhouse gas emissions;...

Hydroelectric energy is a major source of renewable electricity in the world. The industry is continuously searching for ways to improve the efficiency and reliability with which it produces energy. The turbine governor plays vital role in keeping frequency constant. Here we proposed a fuzzy approach to turbine governor by utilizing human experience. The simulation model of Hydro Power Plant (H...

The aims of this study are to enhance the performance of a solar chimney power plant (SCPP), investigate utilization of thermal energy storage (TES) and analyze the environmental impact of the SCPP in providence of Isfahan, Iran. To achieve these goals, multi-stage numerical simulations during twenty-four hours of a day are performed in climate condition of Isfahan province (central region of I...

The Monasavu catchment was selected as an additional study site for biodiversity assessment at the top of the PABITRA wet-zone landscape transect on Viti Levu. The site consists of upland rain forest with cloud forest and a freshwater lake. The lake was constructed to supply hydroelectric power. The biota of the area has been little studied, but initial surveys indicate that many endemic specie...

The aim of this study is giving continuity to the evolution of the SIMPREBAL methodology and computer system based on the specification OSA-CBM (Open System Architecture for Condition Based Maintenance). The operation of the SIMPREBAL (Predictive Maintenance System of Balbina) system mainly is based on the collection and analysis of the monitored physics variables in hydroelectric power plants,...

The excitation system of the hydro unit is a static self-excitation that uses thyristor rectifiers in three-phase fully controllable bridge connection with digital two-channel regulation characterized by very fast response (eng. high initial ratio). powered an transformer connected to busbars aggregate transmission ratio 14.4/0.42 kV. aim this project show characteristics old ABB UNITROL 5000 a...
