Cherepovets state district power station: characteristics and features

Череповецкая ГРЭС – это конденсационная power plant, which is located on the territory of the urban-type settlement called Kadui in the Vologda region of the Russian Federation. This object supplies electricity to the Vologda-Cherepovets node.

Brief information

Cherepovets Hydroelectric Power Station provides drinking water andwarm caduy. This is the largest power plant in the Vologda region. In addition, it belongs to the most large-scale facilities of this kind in the North-West Federal District. Cherepovets GRES has an installed capacity of 1050 MW. The station includes three identical condensing units. Their power is 210 MW. It also includes PGU-420. The Cherepovets Hydroelectric Power Station in the form of this object received a combined-cycle power unit.

Its capacity reaches-420 MW.The first power unit of the station was put into operation in 1976, December 22. The second began working in 1977. The third power unit was commissioned in 1978. The combined cycle gas turbine unit was commissioned in 2014. The main fuel of the station is coal or gas, the backup fuel is fuel oil.

Management

From 2004 to 2008Director of position was Andreyev Yury Vladimirovich. He went to work in Kirishskaya GRES. From 2008 to 2012, the director was Fomichev Oleg Konstantinovich. Previously, this man led GRES-24. From 2013 to 2014 the station director was Shakirov Marat Shavkatovich. Previously, he served as deputy chief engineer for industrial safety at OGK-2. Since 2014, the director is Filippov Viktor Yuryevich. Previously, he worked at Serovskaya GRES as Deputy Head and Chief Engineer.

Power characteristic

The main scheme of this station is one and a half.The installed capacity of the facility is 1050 MW. Now consider what objects are part of the first stage power unit. The description should begin with a double-shell drum boiler. It is designed to function on milled peat. The boiler supports natural circulation. The station also has a condensing turbine unit with a capacity of 210 MW. Seven unregulated selections are provided. The object is single-shaft and supports intermediate superheating of steam.

The station is equipped with a synchronous generatorAC power 210 MW. Provides hydrogen cooling and brushless thyristor excitation type BTV-300. The facility is equipped with a block transformer with a power of 250 MVA. Above, we described the main resources available to Cherepovets State District Power Plant.

Unit 4 should be considered separately. It consists of a single-shaft power plant, which relates to a gas steam turbine, and a generator.

In the period 1996 1998 gg.The station boilers were switched to gas combustion. In 2000, the peat boiler unit No. 1 was reconstructed. This made it possible to achieve more economical and efficient burning of Inta coal and natural gas. In 2003, the automated process control system of the first power unit was put into pilot operation.

Construction of the second stage

In 2010, the Board of Directors of the company "OGK-6"determined the winner in the competition for the construction of a new station unit. Thus, the construction of the Cherepovets GRES during the second phase was entrusted to the engineering company of Mikhail Abyzov called “E4 Group”. The power of the combined-cycle power unit, which was erected and became part of the station, is 420 MW. In accordance with the contract, the amount of the contract amounted to 17.8 billion rubles. The supplier of equipment for the new unit was Siemens.

Also at the facility are used variousauxiliary technical elements from domestic manufacturers. Work on the construction of a new power unit started in 2011. The object was commissioned in 2014.

additional information

Cherepovets GRES is a very large enterprise.It employs 557 people. The competitors of the enterprise are stations that are connected to the area through a 500 kV power transmission line - these are Kostroma and Konakovskaya GRES with maneuverable generation. Also Kalinin NPP can be attributed to the list of competitors. The station we are interested in is not subject to seasonal power limitations. This is a condensing type power station. Since November 2011, the company has been part of Wholesale Generating Company No. 2.

Коэффициент использования мощности достигает 46 %.The station is capable of operating on German coal grades. On average, the company consumes 562 million cubic meters of gas and 733 thousand tons of coal per year. In 2003, an automated process control system for unit No. 1 was put into pilot operation. Theoretically, the commissioning of a new power unit should increase the efficiency of the enterprise to a figure of 52-58%.

In this case, the specific fuel consumption candecrease to 220.1 g per kW per hour. OGK-2 increased electricity generation by 7.1%. The growth rate can be explained by an increase in the load of blocks. Heat production decreased by 3.3%.
