Power and automation technology group ABB announced that it will build the Spanish island of El Hierro project leading

solutions to support the island became the world s first full use of renewable energy island.

It is reported, El Hierro Island, renewable energy projects a total investment of $ 87 million, including wind power

and pumped storage power station construction. The entire project will eventually provide the island s 11,000

residents adequate power supply. ABB, the leading power and automation technology major role in the project. El Hierro

Island project includes a 11.5 MW wind power plant and a 11.3-megawatt pumped-storage power plant construction. They

meet the island s 11,000 residents in 80% of electricity demand, the remaining 20% ​​will be through the solar collector

and grid-connected photovoltaic power generation system to meet.

Island of El Hierro in the Atlantic Ocean, 1500 km from the coast of Spain, is a famous tourist destination in Europe

Canary Islands in the sun the smallest, the farthest island. And other islands far from land as, El Hierro Island, has

been using diesel tanker transport from the mainland to the island dock to generate electricity. In this way a large

amount of carbon emissions, El Hierro Island, only a year on electricity generation up to 18,200 tons of carbon

dioxide, and new renewable energy projects can significantly reduce carbon emissions.

According to reports, ABB in project construction to provide the leading power and automation solutions for the

realization of electric and pumped storage power plant control, and wind power plants and hydroelectric power

generated by smoothly into the island s power grid. Provides solutions including the construction of an equipment

UniGear and UniMix medium voltage switchgear substation, is responsible for five groups of fans and hydro power

generated by the distribution transformer and Relion ® REF 670 intelligent protection system to carry to the island

the main substation.

Throughout the project, the successful installation of automatic generation control system (AGC) is ABB successfully

overcome a major challenge. The system mainly through the distribution line connecting the generator and the active

and reactive power, frequency and voltage to ensure stable power stations, so that plants can respond to a greater

load fluctuations and maintain stable operation. Within the two pumping stations, ABB motor, inverter and dry type

transformers to ensure stable pump operation and the smooth and efficient workflow, while minimizing energy

consumption level and reduce equipment wear and tear.

El Hierro Island, parts of construction projects through ABB distributed control system (DCS) for control. The control

system can be based on ABB 800xA extended automation system platform, responsible for controlling the four groups

hydro, pumped storage, new and existing substations operation of the facility, as well as new wind farms to achieve

communication.

To achieve communication with the wind farm, ABB control system in wind farms can not meet the local demand for

electricity, you can automatically control the upstream reservoir to drain power station. When excess wind power, wind

power can be used to wind the upstream reservoir pumping to prepare for production of hydroelectric power is low.

In addition, according to Greek Lcaria Island is the island of El Hierro renewable energy model building its own

hydroelectric and wind power projects. The power industry are closely watching the progress of this project to

consider the construction of similar facilities in a larger scale.
