30 CHAPTER 5 TURBINES 5.1 Introduction Hydraulic turbines are the machines which use the energy of water and convert it to mechanical energy. The mechanical energy developed by a turbine is used in running an electric generator which is directly coupled to the shaft of the turbine. The electric generator thus develops electric power‚ which is known as hydro-electric power. 5.2 Elements of Hydraulic Power Plants Fig.5.1 General Layout of a Hydraulic Power Plant 31

harnessing the power of flowing water. The power is generated by channeling the flow through a turbine which rotates a generator and creates the power. The most common location for instillation of a hydroelectric power plant is at a dam. The water develops potential energy while it is stored in the reservoir behind the dam and is then gravity feed through extremely large steel pipes into the turbine. The pipes used are referred to as penstocks. In large-scale power plants‚ the penstocks can easily

It hit the South West & South East of England with a maximum gust of 122 mph in Norfolk. In addition the highest hourly mean wind speed was 85 mph at Shoreham-by-Sea and was sustained for 20 minutes. The social damage was huge; 19 people were killed‚ mainly from collapsing buildings and structures or falling debris. However had this storm been during the day time the death toll

DESIGN OF A SMALL SCALE PELTON TURBINE RIG FOR USE IN A LABORATORY Abstract Contents Introduction Aims and objectives The aim of this project is to design a simple Pelton wheel rig for experimental use in a university laboratory. The final design should be able to be built with the equipment and resources at the university and be able to be operated with the most basic knowledge of water turbines. This report also goes into the theory of turbines and power generation‚ particularly

Ireland. The site chosen as the focus for this case study required significant refurbishment work to be completed at an estimated cost of approximately €55‚000 as quoted by one manufacturer in March 2009. This investment would render the hydro turbine fit for operation for years to come and equip the installation with an import/export metering arrangement which would permit the sale of surplus power not required on site‚ to be sold to the ESB. There are hundreds of old hydro sites in Ireland

In its simplest form it consists of steam generation equipment (boiler or nuclear reactor) and a turbine driving an electrical generator. The energy sources available in the world include coal‚ oil‚ gas‚ nuclear‚ hydroelectric‚ wind‚ solar‚ refuse-based and biomass. We can broadly categorize power plants into the following classes. I.
