Array ( [ID] => 231052 [~ID] => 231052 [NAME] => FGC UES has allocated RUB 75 mln to protect two power transmission lines delivering power to Sayano–Shushenskaya Dam against ice [~NAME] => FGC UES has allocated RUB 75 mln to protect two power transmission lines delivering power to Sayano–Shushenskaya Dam against ice [IBLOCK_ID] => 36 [~IBLOCK_ID] => 36 [IBLOCK_SECTION_ID] => [~IBLOCK_SECTION_ID] => [DETAIL_TEXT] =>
In preparation for the autumn and winter period, FGC UES has modernized 500 kV overhead lines ensuring power transit from Sayano-Shushenskaya Dam to 500 kV Novokuznetskaya substation. At the mountain section with a length of 132 km, a ground cable resistant to snow build-up was used, and an automated ice load monitoring system was introduced for the first time in Siberia. Performed works will increase the reliability of power transmission from the largest power plant in Russia to the consumers in Kuzbass.

Total length of transit is 900 km. The mountain section covers the Sayany and Altai mountains at the height of up to 2,930 m above sea level. Over the last years, snow periodically has built up on the ground cable, which may cause short circuit.

To minimize the risk, it was decided to use a ground cable made of steel and aluminized. It is lighter than its traditional equivalents, resistant to snow build-up and less prone to corrosion and vibration. Upon partial damage, such cable does not untwist, which significantly reduces the risk of emergency. Additionally, to prevent vibration (“dancing”) of ground wire, about 1.9 thousand of oscillation limiters have been installed.

Moreover, on the difficult transit section, for the first time in Siberia, an automated ice load monitoring system made in Russia has been introduced. Seven integrated control stations record the ice formation on the power transmission line in the online mode and transmit this information to the Main Center for Control over the Grids of the branch of FGC UES, MES of Siberia. This helps to take operative measures to prevent the emergency conditions. 

Sayano-Shushenskaya Dam is located on the border between the Republic of Khakassia and Krasnoyarsk Krai. Its installed capacity is 6.4 thousand MW, which makes it the largest power plant in Russia. Electricity transit to Kuzbass is performed via two power transmission lines with a length of 450 km each. The first circuit was put into operation in 1983, the second one - in 1985.
