Wind turbines - Part 25-5: Communications for monitoring and control of wind power plants - Conformance testing (IEC 61400-25-5:2006); German version EN 61400-25-5:2007, text in English
There are many steps involved from the development and production of a device to the proper
runnin9 of a complete system designed accordin9 the specific needs of a customer. Suitable
test steps are incorporated in this process.
Many anternal tests during the development of a device (or a system kit) result in a type test
(unit level test) performed at least by the provider and - if required by applicable standards -
by an independent test authority. In the context of this part of the IEC 61400-25 series, the
term type test is restricted to the functional behaviour of the device excludin9 communication.
Continuing routine tests in the production chain are necessary to ensure a constant quality of
delivered devices in accordance with the quality procedures of the producer.
A conformance test is the type test for communication and - since communication establishes
a system - the basic integrated systems test of the incorporated system components. As a
global communications standard, the IEC 61400-25 series includes standardised conformance
tests to insure that all suppliers comply with applicable requirements.
Type tests and conformance tests do not completely guarantee that all functional and
performance requirements are met. However, when properly performed, such tests
significantly reduce the risk of costly problems occurring during system integration in the
factory and on-site.
Conformance testing does not replace project specific system tests such as the FAT and SAT.
The FAT and SAT are based on customer requirements for a dedicated WPP system and are
done by the system integrator and normally witnessed by the customer. These tests increase
the confidence level that all potential problems in the system have been identified and solved.
These tests establish that the delivered WPP system is performin9 as specified.
