Cherepovets state district power station: characteristics and features

Cherepovets GRES is a condensation power plant that is located on the territory of an urban settlement called Kaduy in the Vologda region of the Russian Federation. This facility supplies electricity to the Vologda-Cherepovets site.

Brief information

Cherepovets GRES provides drinking water and heat to Kaduy. This is the largest power plant in the Vologda region. In addition, it refers 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 power units. Their power is 210 MW. It also includes CCGT-420. The Cherepovets state district power station in the form of this facility received a combined-cycle power unit.

Its power reaches-420 MW. The first power unit of the station was put into operation in 1976, on December 22. The second started working in 1977. The third power unit was launched in 1978. The steam and gas power unit was put into operation in 2014. The main fuel of the station is coal or gas, the reserve fuel is black oil.

Management

From 2004 to 2008 The post of director was occupied by Andreev Jury Vladimirovich. He went to work in the Kirishskaya GRES. From 2008 to 2012, the director was Fomichev Oleg Konstantinovich. Earlier this man was in charge of GRES-24. From 2013 to 2014 Shakirov Marat Shavkatovich was the director of the station. Previously, he held the post of Deputy Chief Engineer for Industrial Safety OGK-2. Since 2014 the director is Filippov Viktor Yurievich. Previously, he worked at the 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 let us consider which objects are part of the power unit of the first stage. Start the description with a double-hull drum boiler. It is designed to function on milling peat. The boiler maintains natural circulation. The station also has a condensing turbine unit with a capacity of 210 MW. There are seven unregulated selections. The object is single-shaft and maintains an intermediate superheat of steam.

The station is equipped with a synchronous alternator with a capacity of 210 MW. Provided for hydrogen cooling and brushless thyristor excitation type BTV-300. The facility is equipped with a block transformer with a capacity of 250 MVA. Above, we described the main resources available to Cherepovets GRES.

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

In the period 1996-1999. The transfer of the plant's boilers to the combustion of gas was carried out. In 2000, the peat-boiler of Block No. 1 was reconstructed. This allowed for more economical and efficient combustion of Intinsky coal and natural gas. In 2003, the 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 tender for erecting a new station block. Thus, the construction of the Cherepovets GRES during the second phase was entrusted to the engineering company Mikhail Abyzov under the name "E4 Group". The capacity of the combined-cycle power unit, which was built and entered the station, is 420 MW. In accordance with the contract, the amount of the contract amounted to 17.8 billion rubles. The supplier of the new unit was Siemens.

Also on the site are used various auxiliary technical elements from domestic producers. Work on the construction of a new power unit was launched in 2011. The facility was put into operation in 2014.

additional information

Cherepovets GRES is a very large enterprise. It employs 557 people. The competitors of the enterprise are the stations that are connected to the district through 500 kV transmission lines - Kostroma and Konakovskaya GRES with maneuvering generation. Also, the list of competitors can be attributed to Kalinin NPP. The station of interest to us does not have seasonal restrictions on power. It is a power station of condensation type. Starting from November 2011 the company is part of the "Wholesale Generation Company No. 2".

The power utilization factor reaches 46%. The station is capable of operating on German marks of coal. In a year the average enterprise consumes 562 million cubic meters of gas and 733 thousand tons of coal. In 2003, the automated process control system of Unit No. 1 was put into pilot operation. In 2011, the station began construction of a combined-cycle plant called PGU-420. Theoretically, the commissioning of a new power unit should increase the efficiency of the enterprise to 52-58%.

At the same time, specific fuel consumption may decrease to 220.1 g per kWh. "OGK-2" increased electricity generation by 7.1%. The growth of the indicator can be explained by the increase in the loading of blocks The production of heat decreased by 3.3%.
