UNIT-6  POWER PLANT ECONOMICS AND ENVIRONMENTAL CONSIDERATIONS :   Capital cost, investment of fixed charges, operating costs, general arrangement of power distribution, load curves, load duration curve, definitions of connected load, maximum demand, demand factor, average load, load factor, diversity factor – related exercises. effluents from power plants and Impact on environment – pollutants and pollution standards– methods of pollution control. Types of Loads Residential Load  This type of load includes domestic lights, power needed for domestic appliances such as radios, television, water heaters, refrigerators, electric cookers and small motors for pumping water. Commercial Load  It includes lighting for shops, advertisements and electrical appliances used in shops and restaurants, etc. Industrial Load  It consists of load demand of various industries. Municipal Load  It consists of street lighting, power required for water supply and drainage purposes. Irrigati

UNIT-3 HYDRO ELECTRIC POWER PLANT : Water power – hydro-logical cycle / flow measurement – drainage area characteristics - hydro graphs - storage and pondage - classification of dams and spill ways. HYDRO PROJECTS AND PLANT : Classification – typical layouts – plant auxiliaries – plant operation pumped storage plants. Introduction to Water Power : Hydro power or water power (from Greek) is power derived from the energy of falling water or fast running water, which may be harnessed for useful purposes. Since ancient times, hydro power from many kinds of watermills has been used as a renewable energy source for irrigation and the operation of various mechanical devices, such as gristmills, sawmills, textile mills, trip hammers, dock cranes, domestic lifts, and ore mills. A tromp, which produces compressed air from falling water, is sometimes used to power other machinery at a distance. Hydro Cycle / Water Cycle / Hydro-logical Cycle : The sun, which drives the w

UNIT – 2 INTERNAL COMBUSTION AND GAS TURBINE POWER PLANTS :  DIESEL POWER PLANT : Plant layout with auxiliaries – fuel supply system, air starting equipment, super charging. GAS TURBINE PLANT : Introduction,classification-construction layout with auxiliaries,combined cycle power plants and comparison. Diesel Power Plant Layout : Applications of diesel power plant: Diesel power plant is in the range of 2 to 50 MW capacity. They are used as central station for small or medium power supplies. They can be used as stand-by plants to hydro-electric power plants and steam power plants for emergency services. They can be used as peak load plants in combinations with thermal or hydro-plants. They are quite suitable for mobile power generation and are widely used in transportation systems such as automobiles, railways, air planes and ships. Now-a-days power cut has become a regular feature for industries. The only solution to tide over
