HYDRO ELECTRIC POWER PLANT Prepared by. Mr. Kamil bin Sahidin

CLOs Upon completion of this course, all of you should be able to: CLO 2: Generalize specifically the concept of power generation including steam power plant, gas turbine power plant, diesel power plant, hydro power plant, nuclear power plant, process cycle and terms used in power plant engineering. CLO 3: Identify the applications, main components, related equipments, various arrangements, plant auxiliaries, classifications and comparison between various types of power plant.

Define Hydroelectric p.p Hydropower or hydroelectric power is power that is derived from the force of energy of moving water.

Classify of Hydro p.p Arability of head Nature of load Quantity of water Available

Arability of head To generate a requisite quantity of power it is necessary that a large quantity of water at a sufficient head should be available.

Nature of Load It is paramount importance that the power plant should be set up near the load center; this will reduce the cost of erection & maintenance of transmission line.

Quantity of water available This is the important aspect To decide the capacity of the hydro electric plant Setting up of peak load plant steam, diesel or gt. To provide adequate spillways or gate relief during the flood period
