Visit to Energy Park, Kulcs, Hungary Print

On December, 10th 2010, we (Economic High school Arad, CEA) organized a visit to a Wind Park in Kulcs, Hungary. This park is situated  59 km south from Budapest, close to Kulcs on the bank of the Danube, on the top of a hill .The first grid connected 600 k-W nominal capacity wind mill started its operation in the summer of 2001. 56 students and 2 teachers from Economic High school Arad performed the visit.

Excursion to Renewable Energy ParkBefore leaving, the students were informed about how electricity is produced using wind power. Kinetic energy of a propeller blade collects the wind that turns into electricity through a generator.  A wind farm is a group of wind turbines in the same location used for production of electric power. Individual turbines are interconnected with a medium voltage (usually 34.5 kV) power collection system and communication network. At a substation, this medium-voltage electrical current is increased in voltage with a transformer for connection to the high voltage transmission system. A large wind farm may consist of several hundred individual wind turbines, and cover an extended area of hundreds of square miles, but the land between the turbines may be used for agricultural or other purposes.

Students have admired these turbines and have been impressed by their size. This output has reached its goal, students have seen that electricity can be directly produced without emitting pollutants and greenhouse gases, because it does not burn fuel, producing no waste and energy costs per unit produced are reduced.

After this visit, the students have performed essays on the topic "Alternative Energy Sources».

Location: 59 km south from Budapest, close to Kulcs on the bank of the Danube, on the top of a hill

Technical Description: The generator is 600- kW made by ENERCON. Foundation with 12 m diameter and 1.5 m deep. The diameter of the 3 blades is 44 meter. The tower is 65 m high with a diameter of 2,4 m (down)- 1.2 m (top) weighing 94 tones. The sickness of the wall is in average of 20 mIt starts to work at the wind speed of 2,5 m/s and stops when the wind speEd is more than 25 m/s.
