Magadan CHP

Magadan CHP is a thermal power plant ( combined heat and power plant ) with combined generation of electricity and heat. The installed capacity of the power plant is 96 MW (including the diesel part - 21 MW ), the installed heat capacity is 563.8 Gcal / hour (including the steam turbine part - 495 Gcal / hour , electric boilers - 68.8 Gcal / hour ). The design feature of the station is its division into a steam-turbine part, a diesel part, a water-heating boiler room, and an electric boiler. The thermal scheme of the steam-turbine part of the station is made with cross-links along the main streams of steam and water. The project fuel is Urgal coal, which is actually used in the coal of the Kuznetsk coal basin . The station operates according to the heat-generating schedule, in the summer period the power generation of the station is minimal, and electric boilers are used to provide consumers with hot water. Diesel generators play the role of a backup source of energy supply; they are not used in continuous mode. The main equipment of the station includes: ^{[1] [2]}

• turbine unit No. 6 with a capacity of 25 MW, as part of a PT-25 / 30-8.8 / 1 turbine and a TVS-32 generator, was introduced in 2004;
• turbine unit No. 7 with a capacity of 25 MW, as part of a PT-25-90-10M turbine and a TVS-30 generator, was introduced in 1974;
• turbine unit No. 8 with a capacity of 25 MW, as part of a PT-25-90-10M turbine and a TVS-30 generator, was introduced in 2000;
• six 64G diesel generators with a capacity of 3.5 MW each, introduced in 1970-1972.

The steam for turbine units is produced by four boilers BKZ-50-39-F (two of them are in reserve), one boiler BKZ-160-100-F and two boilers BKZ-220-100-F. There is also a water boiler with two boilers KVTK-100 (are in reserve) and an electric boiler with eight boilers EK 10000/6. Flue gases are discharged through two chimneys with a height of 150 and 180 m. Electric power is supplied to the power system from open switchgears (ORU) with a voltage of 35 kV and 110 kV along the following power lines: ^[1]

• 110 kV overhead line Magadanskaya CHP - PS MTs;
• OHL 110 kV Magadanskaya CHP - PS Arman;
• OHTL 110 kV Magadanskaya CHP - PS Central;
• 35 kV overhead line Magadanskaya CHPP - DES - PS Morport Base;
• 35 kV overhead line Magadanskaya - Severnaya PS.

The first power station with a capacity of only 18 liters. with. was built in Magadan in 1931. In 1933, it was supplemented by a locomobile power plant with a capacity of 660 kW erected by Dalstroi. By the end of the 1950s, there were several small power plants and boiler houses in Magadan that could not meet the needs of the city. As a result, it was decided to build a new power plant in the north of the city, near the Kamenushka River (a tributary of the Magadanka ). Construction of the station was carried out in difficult climatic conditions of permafrost . The first stage of the Magadan district power station was commissioned in December 1962, in 1964 the construction of the first stage of the station with a capacity of 26 MW was completed ^{[3] [4]} .

It was assumed that with the commissioning of a power station in Magadan, it would be possible to eliminate all heating boilers that had heavily polluted the air. But by 1966, the capacity of the new station was not enough, and the question arose of expanding the station. In May 1968, the Magadan Regional Electric Networks gets its present name - Magadan CHP. In 1972, construction of the second stage of the station for higher steam parameters was started, which was completed in 1976. At the same time mounted diesel power plant. As a result, the capacity of the Magadan CHP increased to 122 MW. In 1989–1995, a water heating boiler house was built ^{[5] [3] [4]} .

With the full capacity of the Kolyma hydroelectric station in the Magadan region in the summer, there was a significant excess of electricity. This allowed in the 1990s to decommission worn out equipment of the first stage of the Magadan CHP, as well as to assemble the electric boiler in 1998-2001, which allowed the city to provide hot water in the summer without the cost of expensive imported coal. Initially, the Magadanskaya CHP was designed to burn coal from the Urgalsky deposit, but in the early 1990s, due to an accident at the Urgalskaya mine, the supply of project fuel was limited, and to solve this problem, the station was converted to burning Kuznetsk coals ^{[3] [4]} .

Currently, the Magadanskaya CHPP is part of the central energy center of the Magadan energy system, operating in isolation from the UES of Russia . The station operates in the mode of combined generation of electric and thermal energy, being the main source of thermal energy for the Magadan district heating system. The operation mode of the station is determined by the need to save coal and excess hydropower. In fact, the CHP acts as a net consumer of electricity: in winter, the station carries a load of 5 to 30 MW on the heat schedule, but consumes up to 45 MW of switched on electric boilers, only electric boilers work in summer ^[1] .
