Text 6. Ukrainian hydropower engineering

1. Look though the following text and give the main idea.

Ukrainian hydropower engineering is hydropower units of Dniepro cascade – Kyiv, Kaniv, Kremenchuk, Dnieprodzerzhyns'k, Dniepro, Kakhovka hydropower units, Kyiv hydroelectric pumped storage power station and Dniester hydroelectric power station.

Nowadays total determined capacity of large-scale HPS of Ukraine equals 4700 MW. Ukrainian waterpower resources amount to approximately 45 billions kilowatt/hour among them potentially available and economically appropriate HPS are estimated up to 20-22 billions kilowatt/hour. Approximately a half of them is mastered. A share of hydraulic power in the total production equals fi-7% (11 billions kilowatt per annum). All HPS operate in correspondence with extremely peak maneuver regime, except for 1,5-2,5 months during spring flood when HPS operate under base performance.

It is constructed one of the powerful HPSPP in Europe numbering to Dniester cascade, namely: Dniester one with 2856 megawatt. One proceeds with building, viz: Kaniv and Tashlyts'k HPSPP.

The operation schedules of hydroelectric power stations of Dniepro cascade are carried out along with economic and optimal stream application consideration for power engineering needs and other sectors requirements assurance: fish industry, irrigation engineering, water supply and river transport.

Construction of Dniester control structure (Dniester operating HPS and buffer HPS belong to it) enables to enlarge an area of irrigated grounds and provide industry and region's population with water supply.

2. Discuss the following information in small groups and answer the questions:

– What hydropower units of Dniepro cascade do you know?

– What is a share of hydraulic power in the total production of energy?

– Does construction of Dniester control structure enable to enlarge an area of irrigated grounds and provide industry and region’s population with water supply?

3. Look through the text again and find English equivalents for the following terms and word-combinations:

гідроакумулююча електростанція, загальна встановлена потужність, гідроенергетичні ресурси, гостропіковий маневренний режим, весняна повінь, базовий режим, Дністровський каскад, рибне господарство, зрошування, водопостачання, річковий транспорт, буферна ГЕС, площа зрошувальних земель.

Text 7.

1. Read the text below and give a title to it; say what new you have learnt and what you are familiar with:

1. In 1994 it was established "Dnieprohydroenergo" state company. All HPS of Dniepro cascade and "Dniestrohydroenergo" (Dniester HPS) state company became a part of "Dnieprohydroenergo" state company.

2. In 2004 in order to improve social and economic importance of hydropower engineering, its influence upon manufactured hydroelectricity quality and electric power system reliability and security State corporation hydropower generating company "Dnieprohydroenergo" and "Dniestro­hydroenergo" state company were reorganized via their merge. It was incorporated "Ukrhydroenergo" public corporation on their basis.

3. Taking into consideration a special role of HPS in national economics, management of the branch and company brought up a question on necessity of the HPS fundamental reconstruction carrying out in the Dniepro River via the program of reconstruction and technical re-equipment at the end of the eighties years.

4. An average age of Dniepro HPS up to the moment of the present question solution stated approximately 35 years (age of five HPS equaled more than 30 years, Dniepro hydroelectric station – approximately 50 years (after renovation).

5. During these years technical state of the crucial hydro constructions and equipment of HPS under the conditions of their complex heavy use resulted in boosted wear and tear and physical aging.

At that time the planned Program was postponed because of the difficult financial-economic situation in the country and industry.

6. In 1995 after comprehensive estimation of economic, social and ecological possibilities, which was carried out jointly by the experts of the World Bank, Ukrainian specialists and board of directors of the World Bank, it was reached a decision on partial (approximately 40%) share of the World Bank in the 1st stage of the Project of HPS reconstruction. The total amount of investment on the part of western investors stated 53 million US dollars. The local share of the first project stage, equaled 70 million US dollars. In April 1996 the Agreement between Ukrainian government, which is a guarantor of loan resumption, and the World Bank was ratified by Verkhovna Rada of Ukraine.

7. The peculiarity of the reconstruction carrying out is the following, viz: it has been performed at the operating HPS. It was concluded ten international contracts with some prominent companies: Alstom, ABB, Alpha, HAEFELY TRENCH, Telemac.

8. From 1997 one commenced a supply of import electric equipment, which was not manufactured by Ukrainian works (water turbines speed regulators, excitation systems of generators, high voltage SF6 circuit breakers, high voltage switches, relay protection, hydroelectric generating sets automatic control systems).

In order to implement rehabilitation project of HPS it was engaged approximately 10 thousands Ukrainian specialists.
