Wind Tech: Monitoring system for Gamesa and more

SPAIN: Gamesa and Iberdrola have created a remote management system allowing them to potentially control any turbine around the world.

The WindCore and WindOne system allows project operators to remotely analyse data from projects in real time.

Data gathered by the control system includes wind speed at each turbine, temperature and power output of the machines, using one system. This data helps owners predict operations-and-maintenance work.

Gamesa and Iberdrola are making the system available to all their customers. It can be used on any make of turbine via a single interface, removing the need for different software programmes.

Gamesa said it already operates more than 400 wind projects globally from its control centre in Spain.

"The versatility of WindCore and WindOne will pave the way for its implementation in any environment while respecting each customer's proprietary communications network infrastructure and management tools," said Javier Ontanon Ruiz, head of remote control developments.

Life extension system

The remote management system coincides with DNV GL's certification of Gamesa's upgrade programme, which is intended to extend the life of its G47-660kW turbines to 30 years.

The certification body has confirmed that Gamesa's structural upgrades and monitoring features can extend the life of the turbines from the standard 20 years to 30 years.

Gamesa will now work on applying the life-extension programme to its 850kW and 2MW turbines, and to machines from other manufacturers maintained by Gamesa.

DNV GL said its certification was based on analysis of the design, specifications and applied calculations over the entire life of a G47-660kW turbine, based on its Guideline for Continued Operation of Wind Turbines 2009.

"The ability to extend the useful life of a turbine is a key step in maximising efficiency and reducing costs in the global wind-energy market," said Andreas Schroeter, executive vice-president of the renewables certification division of DNV GL.

Gamesa said the extra ten years of operation would make the turbines more profitable over their lifetime.

Enercon recently launched a new 4MW turbine platform that it said will last for 30 years rather than the standard 20 years of most turbines. It is thought to be the first turbine platform specifically developed with this longer life.
