5 Construction of Thermal Power Plants construction of Thermal Power Plants Based on Steam-Power and Gas-Steam Cycle By rough estimate, due to tremendous growth of the rate of global economic development, growth of population, and other geopolitical and economic factors, power consumption in the world will at least double by the middle of the XXI century. So far, power engineering, without any alternative, has been the major driving force behind the world progress. Despite major breakthroughs in the field of technical innovations, and rapid development of alternative power sources, traditional power engineering (power plants using the steampower and gas-steam cycles) is still the basis of the world energy supply. According to different sources, 39 % of all electric energy in the world is produced with oil, 27 % with coal, and 24 % with gas. Advantages of traditional thermal power plants are obvious long-term experience of construction engineering, relative tie-in to the fuel deposit locations compared to other types of power plants, and also absence of seasonal fluctuations in power production. Traditional power engineering has been developing progressively. And although a few decades ago preferences were given to the building of power plants using steam power cycle, now the intensive search for higher efficiency has given rise to the development of gas-steam technologies, and the increase in the number of newly commissioned CCGT plants. Experience of the gas-steam technologies use in power plants has demonstrated substantial growth of efficiency factor. A combination of the gas-turbine and steam-turbine plants in one power-generating unit made is possible to raise the efficiency of the use of fuel to 60 %, i.e. up to the level, which other thermal machines cannot attain. The use of the CCGT installations also made it possible to improve ecological characteristics of the TPPs, in particular, due to lower emission of nitrogen oxides. All these obvious advantages have brought about a situation, where almost 70 % of commissioned power plants today all over the world use the combined-cycle installations. 3

23 Construction of Thermal Power Plants TPP Mezhdunarodnaya, Russia The TPP Mezhdunarodnaya (phase II) is a power plant, where the Technopromexport specialists have included the most advanced solutions and developments of the power engineering industry in the design. Such power plant is an optimum solution for municipal power engineering in big cities because the area of power plant construction site complies with the most stringent requirements of the compact urban development. The area of the plot of land and that of the TPP buildings and structures is 1.88 ha and 1.61 ha respectively. It equals the area of a district thermal plant (DTР) for a large community area. An important factor is also a possibility to arrange the TPP facilities in close proximity to the consumers of thermal and electric energy, and for fitting the TPP in the new community areas. Ecological requirements to the plant operation meet the most stringent specifications applied in the world power engineering. The main building of the plant is characterized by compact arrangement of the main process and auxiliary equipment. Installed on the roof of the power house of the main building are the units of the dry-air cooling towers to remove excessive heat generated by the TPP gas-steam cycle, and also the units of the integral cooling systems for various plant equipment: oil systems of the GTP and the steam turbine. The dry-air blower-type cooling tower is equipped with controlled swiveling louver mechanism to automatically control the cooling air flow depending on the cooling water temperature. The plant uses frequency regulation of the electromechanical equipment, which helps to increase the service life of the equipment and to reduce consumption for own needs. The state-of-the-art water purification technologies using reverse osmosis (membrane technologies) help to achieve the required quality of water with the use of a compact-size TPP watertreatment system. The output power is 20 kv and 110 kv voltage. The 110 kv gas-insulated switchgear and control gear is an enclosed cubicle of the latest design, which practically requires no operational expenses. For the first time, the TPP Mezhdunarodhaya uses small-size monolithic three-phase bus ducts with polymer filling. The plant capital equipment has local monitoring and control systems combined in an integrated PCS. The high degree of automation of the process and electrical equipment helped to minimize handwork during the plant start-up and normal operation. The equipment monitoring and control is carried out by the power-generating unit operators from the main control panel using computer network. The period of the plant construction has been considerably reduced to 17 months instead of the scheduled 24 months.

29 Construction of Thermal Power Plants Power-Generating Unit CCGT 450 MW Yuzhnaya CHP-22, Russia Expansion of Yuzhnaya CHP-22 using gassteam combined cycle was carried out with a view of providing electric and thermal power to the industrial and communal facilities of St. Petersburg by building CCGT- 450 MW. When developing the project Feasibility Report, specialists of Technopromexport have made provisions for further expansion of Yuzhnaya CHP-22. The new power-generating unit was erected in the heat generation plant territory as a separate building connected by process lines with the existing facilities. The new power-generating operates in the basic roundthe-clock mode and with the maximum possible number of hours of use of electric and thermal energy according to the loading schedule. To effectively use the limited territory of the construction site of a new gas-steam powergenerating unit, use was made of vertically configured heat-recovery boilers. This helped to significantly reduce the construction site area. The use of forced circulation in the HP and LP circuits of the vertical heat-recovery boiler increased its reliability in low-load operation and in starting conditions. The main equipment of unit 4 of CCGT-450 of Yuzhnaya CHP-22 included: two gas-turbine installations, type ГТЭ-160, produced by OJSC Power Machines (LMZ), two heat-recovery boilers for two pressure ratings produced by OJSC Podolsk machine-building factory, and one steam-turbine plant of the heating type with adjustable steam extraction for heating produced by OJSC Power Machines. The equipment has been tested at the main power-generating unit CCGT-450 installed at the North-West CHP in St. Petersburg, and also at other similar facilities Kaliningradskaya CHP-2, and CHP-21 and CHP -27 in Moscow.
