Uglegorsk TPP: information, description, where is located

Uglegorskaya TPP is one of the two most powerful thermal power plants in Ukraine with a peak capacity of 3,600 MW. In the structure of the enterprise there are 7 power units, four of which are designed for burning of gas coals, the remaining three operate on fuel oil or natural gas. The station is a structural subdivision of the Public Joint Stock Company "Centrenergo".

Description

Uglegorsk TPP is a powerful heat and power complex capable of generating up to 3600 MW of electricity, which is an absolute record for Ukrainian TPPs. A similar station, built on the same project, is located near Zaporozhye.

Uglegorsk TPP is designed to provide thermal and electrical energy to consumers in the Donetsk region - the most developed in the industrial sector. The station consists of two parts: the first is oriented to work with coal gas brands, the second - gas (fuel oil).

Where is Uglegorsk TPP

The thermal power plant is located in the administrative boundaries of the Donetsk region, in the Bahmut district. In 2-3 kilometers from it there are settlements Mironovsky, Novolugansk and the satellite town Svetlodarsk, built for the personnel of TPP. The nearest major city is Gorlovka, located 8 km southeast of the station. Company Address: 84792, Donetsk Region, Svetlodarsk-1.

Characteristic

General information about Uglegorsk TPP indicates that the design capacity of the most productive second stage is designed to receive 2,400 MW. Three power units are installed in its halls, each of which is equipped with a 800 MW turbo-unit and a gas-oil single-boiler with a steam output of 2,650 tons per hour. The turbine units are equipped with heating plants that produce 15 Gcal of heat per hour.

The first stage of the Uglegorsk TPP (which in 2013 went down as a result of a fire) generates 1,200 MW. It consists of 4 power units, equipped with turbo-generators, each generating 300 MW each. Four pulverized-coal single-shell boilers have a steam capacity of 950 t / h. Heat from here goes to the city of power engineers Svetlogorsk and to various industrial sites.

Background of construction

The history of the Uglegorsk TPP begins in the 60s of the XX century. By this time, the region of Donbass, neighboring Dnipropetrovsk, Kharkov, Rostov regions have turned into one of the largest industrial clusters of the Soviet Union. The power of the already erected power plants in peak periods was not enough. The government decided to build the two largest capacitor power plants in Ukraine (later reorganized in TPPs) under the new project: one in Zaporozhye, the second in the north-east of the Donetsk region.

According to the idea, the new power plants had to become more flexible in the production plan: to work on several types of fuel (gas, fuel oil, gas coal), increase and decrease productivity, depending on peak loads during the day and energy consumption drops at night.

Base station

Construction work at the Uglegorskaya GRES began in 1968. Originally built infrastructure facilities, roads, communications, industrial buildings and residential areas of the city of Svetlodorsk. High-voltage backbone lines for the transmission of 330 and 110 kV voltages are connected. On the Lugan River, a dam was built to take water from it for cooling and technical use. Miracles of design thought were shown by Soviet builders: a record high 320-meter chimney was erected at the station.

The launch of the first-generation power unit took place in the winter of 1972. On December 3, a 300 MW coal turbine generator produced the first kilowatts of energy. After the break-in, the GRES was connected to the united power system of the country. In the course of the year, the power industry has gradually put into operation three more units operating on gas coals. By the end of 1973, Uglegorskaya GRES consistently produced 1,200 MW of energy.

Development

1974 for Uglegorskaya TPP was a new stage in development. The construction of a second, more efficient line began, the equipment of which allows using fuel oil or natural gas as a source of fuel. The first 800-megawatt block gave energy in December 1975. A year later, also in December, two more blocks were earned. Thus, the total capacity of all seven power units of the station was 3600 MW.

In 1984, a large-scale reorganization of the management system was carried out at TPPs. All important technological processes were automated in order to exclude as much as possible the errors caused by the so-called "human factor".

After Ukraine gained independence, the Uglegorsk Power Plant passes under the jurisdiction of the new national power. In 1995, the enterprise entered the structure of PJSC "Centrenergo", where it is located to this day. By the way, important stages of the enterprise development are described in the book "History of Uglegorsk TPP".

Conservation of the second stage

The tense relations that developed between the Ukrainian Republic and the Russian Federation in the oil and gas issue led to increased prices for energy. Ukraine has small reserves of gas and oil fields, raw materials have to be purchased in neighboring countries. As a result, the cost of electricity and heat produced by the second stage of the Uglegorsk TPP exceeded the permissible limits. The three most productive 800-megawatt units operating on gas (fuel oil) had to be mothballed. Thus, the actual capacity of the station for today does not exceed 1200 MW.

PE in 2013

On March 29, 2013, at 15:14, a large fire broke out, which occurred due to the ignition of coal dust. As a result, four turbines of the Uglegorsk thermal power plant were destroyed. The accident led to the fact that 12,000 residents of the city of Svetlodarsk were cut off from communications. One employee of the station was killed, and thousands were left without work. The consequences of the disaster were also felt by the miners, and the beginning of financing reconstruction and social support of the population of the affected city led to an increase in the tariff for electricity. However, the stoppage of the work of the Uglegorsk thermal power station did not lead to a disruption in the work of the Ukrainian energy system.

Two weeks later, the situation at Uglegorsk TPP was commented on by Minister Eduard Stavitsky, who oversaw the energy and coal industry. He made a statement that the decision was made not to restore the burned-out 4 blocks, but to repair them in a thorough way.

According to the investigation, the state of emergency resulted in a change in the operating conditions, which resulted in the burning of coal dust. The fire spread to the roof and then spread through the shops of the first stage. By the way, unlike anthracite, gas coals are highly flammable. When they are burned, strict adherence to technical standards is required. Multi-level extinguishing media must be introduced at the enterprise.

The main reason for the emergency is the fact that the absolute majority of generating capacities that were launched during the Soviet era have already exhausted their resources. At least 60% of the capacities in the thermal power industry need urgent replacement, and 90% do not correspond to the concepts of reliable and efficient operation due to the exhaustion of the marginal resource.

Emergency recovery work

Despite significant destruction, the Uglegorsk power plant was not closed. The following several years, large-scale construction and installation works were carried out. Initially, the restoration of the coverage of the machine room No. 1 was provided. On 8/10/2013, the station power unit No. 1 was connected to the integrated power system, unit No. 4 was connected on 13.11.2013. Next, the third power unit was overhauled with the restoration of the ACS systems. In 2014, it was decided to modernize Unit No. 2 in order to restore the main equipment and increase the electrical capacity by 25 MW, to improve environmental performance for dust emissions to 50 mg / Nm ³ .

For more than forty years of continuous operation of Uglegorsk TPP, modernization of power generating equipment has not been carried out. The order of the Ministry of Energy envisages a further sequential reconstruction of the power units No. 1, No. 3, No. 4 with the increase of the electric capacity of the first stage from 1,200 MW to 1,300 MW. Also, the construction of a common plant desulphurization plant was started to improve the ecological state of the region.

Prospects

Increasing the competitiveness of Uglegorsk TPP in the future is expected due to:

• Reducing the cost of electricity;
• Modernization and reconstruction of equipment;
• Increasing the range of maneuverability of the blocks, which is especially important in times of peak loads.

Thus, Uglegorskaya thermal power plant has great potential, but due to the unstable economic and political situation that has developed in Ukraine, the station can not operate at full capacity.
