Session Contents
• Aim: at the end of this session participants will have a quick overview of the fundaments of a modern wind park SCADA system
• Duration: 20-25min

Basics
DefinitionSCADA=Supervisory Control & Data Acquisition
SCADA (Supervisory Control And Data Acquisition) system refers to the combination of telemetry and data acquisition. It consists of collecting information, transferring it back to a central site, carrying out necessary analysis and control, and then displaying this data on a number of operator screens.
The SCADA system is used to monitor and control a plant or equipment. Control may be automatic or can be initiated by operator commands.
6
Basics
What is based on• The central SCADA master system.• A communications network.• The RTU's. Remote Telemetry (or Terminal) Units.• Field instrumentation
7
Basics
DCSSimilar to the SCADA systems are the Distributed Control Systems (DCS).The DCS is usually used in factories and located within a more confined area.It uses a high-speed communications medium, such as local area network (LAN). A significant amount of closed loop control is present on the system.
The SCADA system covers larger geographical areas. It may rely on a variety of communication links such as radio and telephone. Closed loop control is not a high priority in this system.
8
Basics
In the wind industry• Communication interface on the device that has to be
controlled• Communication network• Communication concentrator• “Server” unit• “Client” unit• Man to machine interface
10
Why a SCADA system?
Wind turbines are made to operate unattended!
Manufacturer point of view• Fulfill contractual obbligations on service & reduce
service costs• Get feed-back for product development
Operator/Owner point of view• Verify contractor obbligations• Reporting (various levels)• Integration of different windparks over the country
11
Why a SCADA system?
External requirements• Wind power plant operation• Fulfillment of grid operator requirements
• Active power control• Cooperation to reactive power control• Balck-star connection• Etc.
• Forecasting tools
13
Evolution
Yesterday• Few status signals• Historical data processed at centralized level (raw
signals collection)• Dedicated HW• Dial-up remote connection
Today• WTG=IFD (Intelligent Field Device)• Historical data processed in the WTG• Commercial HW• Broadband connection (Point to many)
15
Requirements
Low demand systems• No external database• Rely on wind turbines internal memory (limited
ammount of data)• No data back-up functionalities• Limited number of wind turbines to be connected• Impossible to connect devices other than
windturbines• No customized features• Standard reporting
16
Requirements
Professional systems• External database• Impossible data loss • Back-up functionalities• Unlimited number of turbines connected• Possible to connect devices other than
windturbines (revenue meters, metereological stations, PLCs, etc)
• Custom features available• Advanced and custom reporting available• High security• Possibility of interfacing other devices on several
different protocols• Etc…

Communication port
Ethernet port
Optic RS232 port
• Hardwired I/O• Serial communication ports (RS232, RS485,
Optical, etc.)• Ethernet
19
Communication Protocols
• Proprietary
• Industrial protocols (ModBus, DNP3,…)
• Standardised protocols: IEC61400-25

Server
Device that manages the continuous collection of data from the units in the wind power plant.Eventually collected data are stored in a central database and used for operating and managing the wind power plant. •Dedicated HW•Host PC•Industrial servers
23
Client
Device hosting the HMI (Human to Machine Interface), the operator's user interface for viewing instant data as well as accessing and processing the collected data from all units in the wind power plant as well as for viewing instantaneous data from the units.
•Remote panels•Client SW hosted in PC
