ABSTRACT

The global electrical energy consumption is arising and there is a steady increase of the
demand on the power capacity, efficient production, distribution and utilization of
energy. The traditional power systems are changing globally, a large number of
dispersed generation units, including both renewable and non-renewable energy sources
such as wind turbines are integrated into systems at the distribution level.
Building up wind turbines supposes a significant investment in the foundation
construction, especially in case of difficult foundation ground conditions. These ground
conditions are found in sites of Dobrogea area from Romania. In this case, there are
necessary special foundations to ensure the proper workability of the foundations. In
this paper are compared two foundation solutions. One of them supposes to apply a soil
improvement technology by realizing compacted granular columns. The second solution
consists in carrying out a limited number of piles under the foundation block.
The conclusion resulted by comparing these two solutions is that the pile foundation
solution is less time consuming and cheaper than the solution consisting in soil
improvement with compacted granular columns.
