WindCORE definition
• A control centre for wind farms that allows remote
supervision, control, and data acquisition 24 / 7 for
Operation and Maintenance
• Able to communicate with other energy management
centres
• Implemented energy control functions to satisfy the
grid operation requirements as of the TSO
(Transmission Operator System)
• Easily scalable by means of aggregation. Although
presently the WindCORE developed for Iberdrola is
managing almost 140 wind farms (4000 wind turbines)
worldwide, these figures could be no limits exceeded.

Customer case: PI Subsystem
1.
Reference: Iberdrola Renewable Energy Operation
Centre
- Currently it operates almost 140 Wind Farms
(including those outside Spain), i.e. 4,000 turbines, i.e.
over 1,200,000 acquired data
- The 250,000 most significant data points are
processed by the PI Subsystem (included an
extension to be executed in the short term)

Customer case: PI Subsystem
1.
Reference: Iberdrola Renewable Energy Operation Centre
- Major parameters of:
•
•
•
Wind Farms (state, pitch angle, main shaft speed, oil temperatures…)
Electrical Substations (active and reactive power, voltage…)
And Meteorological data from each wind turbine (temperatures, barometric
pressures, wind speed…)
are being acquired by the PI Enterprise
server, stored in the Historian subsystem,
and Rt info is being used in trend displays,
Production curves of Wind Farms…
- PI data information being used for the
availabilities calculations in a maintenance
system based on SAP
- Mini-hydraulic stations

Iberdrola is applying its own professional production
management model to wind energy using the CORE data
“Dominate
technology and
key management
factors”
Starting point
 Iberdrola’s 100
years utility culture
 Wide O&M
expertise:
Strategy
 Hydroelectric
 Gas combine
cycles
 Nuclear
 Renewables
 Fuel oil
 Coal
 Cogeneration
Organization &
functions
Systems and
procedures
Main goal
Maximize
economic
performance of
every wind farm
during the
extension of its
lifetime
• Iberdrola doesn’t develop a
wind farm to sell it
• Iberdrola develops to create
value

DOMINA: Production management
•
Iberdrola’s own methodology to obtain production reference for every WTG every day
•
Automatically DOMINA obtains working parameters: unproduced energy, time intervals,
frequencies
•
Parameters turn into indicators that are used to control and manage production
Real production
O&M people at wind farms characterize every single stop occurred, naming causes of
unavailability
Production reference
•
Unproduced Energy
• Gap identification for
particular time
intervals
• Due to

Customer case: PI Subsystem
2.
Reference: Eólica CESA Renewable Energy Operation Centre
- Currently it operates 18 Wind Farms in Spain, i.e. 476 turbines,
i.e. over 155,000 acquired data.
- 20,000 data are processed by the PI Subsystem
- An extension is planned according to the new situation (growth
up to 30 WF)
3.
In addition, Iberdrola has other successfully References with
the PI System:
- The Monitoring, Diagnosis and Simulation Centre (CMDS) for
Iberdrola's world-wide combined cycle facilities
- On-site supervision of the Iberdrola´s Combined Cycle power
plants

WindCORE PI Subsystem
•
Currently WindCORE is the solution for:
– This new process. It´s not known in detail what information it will be necessary
for either Operation and Explotaition, and what will be the real needs of the users
– The huge amount of information (between 200 and 500 data points per
Turbine). Now there are around 1 million data points from the Iberdrola Wind
Farms.
•
The PI subsystem integrated in the WindCORE is able to solve:
– An Historian to store for years all the requested variables in real time, without
previous averages or aggregations
– The averages, ranges , calculations, acumulated data, etc. with whatever time
rate. This means; Whatever I want, Whenever I want, and immediately.
– Web based information of whatever variable on time without cost expensive
specific applications and customizables by the own user.
– A complete environment to optimise the maintenance and exploitation:
calculations from whatver interface (DataLink, ACE, etc.), real time reports,
statistical analyses, etc.
