Technical Guidelines
The development of the Technical Guidelines for Wind Turbines (since 1998: FGW Guidelines) began in 1992 with the aim of specifying measurement procedures with which reliable and comparable data on wind turbines can be determined using state-of-the-art technology. The measurements from the three areas – power curve, noise emission and electrical properties – should serve as a basis for the assessment of wind turbines, e.g. in approval issues, in the assessment of grid connection options or for reliable yield calculations.
The guidelines of the International Energy Agency (IEA), which have been drawn up since the 1980s, allow a broad scope for measurements and analyses. On the other hand, the technical guidelines should create the conditions for making the measurement results comparable, regardless of who carries out the measurements.
Measurements in accordance with the Technical Guidelines can be carried out by all qualified bodies. A report must be prepared on the measurement, the main results of which can be summarised in an extract from the test report in accordance with the specifications given in these guidelines. However, in addition to the requirements described in these Technical Guidelines, it should be noted that the bodies that are to recognise these measurements may impose further requirements on the measuring institutes.
