IEC61400-25-4 on RTU32 in Wind Power application Date : 24-09-2008 Project description
Previous master thesis has created some of the basic software platform for an implementation of IEC61400-25 in real running environment. The main objective for this thesis is to evaluate the basic software platform prepared, make necessary improvements and deploy the solution on an industrial PLC platform, ready to run in a real wind turbine. The project includes as well a validation and test of the solution created.
The industrial PLC is made available by Brodersen Controls A/S, and the implementation of the IEC61400-25 domain is realized using the .NET compact framework C# programming language.
The deployed solution will be tested against a real wind turbine situated at the Risø research facility.
Abstract
In recent times wind power plant vendors have showed increasing interest in the international standard IEC 61400-25 for communication, monitoring and controlling of wind power plants. Before this, vendors had their own specification on how to communicate, monitor and control. Due to rapid market
growth and demands, standardizing in this field is crucial for further expansion.
Previous thesis’s by Andreas Kargård Olsen, Baris Özdil and Umutz Korkmaz has done various concept proofing of the IEC 61400-25 standard. This thesis builds on top of these and moves the domain from standard PC’s to industrial PC’s.
The industrial PC is a Brodersen RTU 32 running Windows CE v5.0 as an operating system. The implementation language is C# running in .NET compact framework 2.0.
The program is a simple server, compiled of various modules ranging from information model, communication profile, client handling and user association verification. The communication part is mapped to web services as of part 4 annex A in IEC 61400-25.
On the client side a dynamic link library (DLL) act as a configurable proxy stub to all IEC 61400-25 servers implementing web services as communication profile. This DLL is tested by the conformance tests as of part 5 of the IEC 61400-25.
The testing method used is based on test driven development, and incorporates unit tests.
