Martyr Lt. Gen. Qassem Soleimani combined cycle power plant in Kerman<\/span><\/strong><\/p>\n

History and goals:<\/span><\/strong><\/p>\n

In order to develop the country’s power generation network, especially to supply and stabilize the voltage of the southeast network in the late seventies, a study was conducted by the Ministry of Energy and based on the plan to build a combined cycle power plant with 8 gas units with a nominal capacity of 159 megawatts per unit at the center of gravity. Kerman was approved. In this way, the first phase of the power plant project, which includes the construction of 8 gas units with a total capacity of 1272 megawatts, actually started in 2019.And through the conclusion of an agreement between the Electricity Development Organization of Iran and the Iran Power Plant Project Management Company (Mapna) and the participation of its foreign partner, namely Ansaldo Italy, as part of the 30 turbine project, the construction and the first unit of it on 4\/16\/1380 and the last The unit was put into operation on 29\/9\/2013. In the construction of the construction of the gas section of the power plant, internal contracting capacities at the level It has been widely used for the development of power plant construction technology.The gas turbines of this power plant are the V94.2 model made by the German Siemens company, which the Italian Ansaldo company sold to Iran under the license of the said company. Next, the steam section of the power plant, consisting of 4 units of 160 MW, was put into operation in 1986 and 1978.<\/p>\n

General characteristics of the power plant:<\/span><\/strong><\/p>\n

The above power plant was built in the 20th kilometer of Kerman highway, Rafsanjan, in an area of \u200b\u200b120 hectares, the gas part of which, as mentioned,
\nconsists of 8 gas units and the steam part also has 4 units with a nominal capacity of 160 megawatts per unit. It started on 10\/83 and the first unit
\nwas put into operation on 12\/28\/86 and the last unit on 12\/22\/87.In total, with the full use of the facilities of the steam department, the nominal capacity of this power plant reached a figure of 1912 megawatts, and later by carrying out upgrading operations on the gas units and installing the media system on 8 gas units, the total capacity of the power plant increased to a figure of 2000 megawatts. In this sense, it is one of several large power plants in the country.<\/p>\n

The main fuel of the power plant is natural gas, and the second fuel is diesel, which is transported to the power plant with the help of pipelines and stored and used in 20 million liter metal tanks and 60 million liter concrete tank. The cost of constructing the gas section of the power plant is about 300 million euros, and the cost of setting up the steam section is almost twice the mentioned amount.The amount of gas and diesel fuel consumption of the power plant per megawatt hour of electric energy production in the open cycle mode is equivalent to 330 cubic meters of gas and 330 liters of diesel, and in the combined cycle mode, it is an average of 223 cubic meters of gas or 223 liters of diesel.<\/p>\n

Power station posts:<\/span><\/strong><\/p>\n

In order to transfer the generated energy in the power plant units, two power station substations have been built. The substation voltage level is 230 kV in the gas sector and 400 kV in the steam sector. The 230 kV substation of the power plant has 19 feeders (9 line feeders, 9 power plant feeders and 1 feeder coupling) and is of double busbar type. The 400 kV substation of the power plant also has 10 feeders, including 3 line feeders, 4 power plant feeders, 1 coupling feeder, and 2 feeders connected to the 230 kV substation.<\/p>\n

What is the combined cycle?<\/span><\/strong><\/p>\n

As shown in the block diagram, each V94.2 gas turbine consists of two combustion chambers installed on both sides of the turbine. After entering them, the fuel (gas or diesel) is ignited by the operation of the sparking system and enters the combustion chamber area with the air that enters the compressor from the inlet filters and exits after being compressed, and burns, producing a gas with a temperature of about 1060 degrees Celsius. The gas enters the gas turbine and causes the turbine to rotate and, as a result, the generator shaft and generates electricity. The output product of the gas turbine is smoke with a temperature of about 550 degrees Celsius, which enters the atmosphere as heat losses through the chimney, and thus the gas turbine has an efficiency of about 33 percent in the best operating conditions. In other words, the other 67 percent is considered as heat losses and is inefficient. The idea of \u200b\u200bthe combined cycle is actually to recycle the 67 percent. In this way, in the exhaust outlet section of each gas turbine, by installing controlled valves, the hot gas is directed to the boiler section, so that the water in it is converted into superheated steam (very hot and dry steam) with a temperature of about 530 degrees Celsius and is used together with the steam output from the second boiler for use in a steam turbine. In this way, in the boiler section, since the heat output from the gas turbine is used for heating, the overall efficiency is increased, reaching a figure equivalent to 47 percent. After working in the steam turbine, this steam drops in temperature and reaches a temperature of about 60 degrees. Here, too, in order to reuse it, the steam is cooled by the cooling system (in the Shahid Soleimani power plant with the help of powerful air fans) and converted into water. After performing intermediate purification operations, it enters the feed tank for reuse, to re-enter the boiler and convert into superheated steam. This cycle is called a combined cycle, and the Shahid Soleimani power plant is considered one of the largest power plants of this type in the country. The water required by this power plant is supplied through several wells drilled in the Chopar plain and is entered and stored in the power plant’s raw water pool with a capacity of 3,200 cubic meters through a pipeline, so that it can be used by the power plant’s boilers after purification operations. The nominal water supply capacity of the said wells is about 80 liters per second.<\/p>\n
