Iran's electric power system

Abstract: Abstract Iran is a very vast country with about 80 million population that they are really fragmented. Providing electricitypower for all the society which is duty of power ministry of Iran according to the resources and facilities. The thesis gives an overview of production of electrical energy in Iran and how the production is divided ondifferent energy sources. At the present time there are 197 power plants are producing electricity to supportthe country that they are combination of 8 kind of different power plants which are thermal power plants, gaspower stations, combined cycles, hydro power plants, biogas plants, wind power stations, solar plants andnuclear power stations. During the last decade Iran took care of renewable energy sources to produce electricitythat cause wind power plants and solar power plants can take a small share from the total production. Althoughthey are not play a serious role yet but the policy of the country is improving these kind of power plants. Foreach source the production principle is described briefly by help of a diagram and also there is a table of allpower plants which are included details of each power plant like: name of power plant, state (location) , year ofinstallation, nominal power, gross power, efficiency, consumption (fuel, water,…) and so on. For each kind ofpower plants there is a bar chart which compares the nominal power of all power plants at a glance and alsothere is a map that the location of each station has been marked on. Total data for production in a year has been presented. Also there is a list of power plants which they are underconstruction and will be ready in future. For transmitting electricity power in the country there are four kind of transmission lines which are: 400 KV, 230KV, 132 KV and 66 KV. The development of each kind of transmission lines since 1963 is presented in a table anda chart. Also Iran has export and import electricity with 8 neighbor countries like: Iraq, Afghanistan, Azerbaijan,Turkmenistan, Turkey, Pakistan, Armenia and Nakhjavan.
