Description
The purpose of this project is to develop an advanced and comprehensive test facility that will enable the wind power industry to develop and validate a much wider range of grid connection characteristics of wind power plants than what is possible at present. The test facility will be based on modern power electronics solutions, aiming at maximum flexibility to enable the more advanced testing of characteristics that are expected to be required in the future.
The test facility will not only fulfill the present needs for validation according to relevant grid codes, but also be able to facilitate the tests of more advanced characteristics in the future. The following issues will be included:
-
Voltage dips and swells
-
Voltage unbalance
-
Voltage and current fluctuations / resonances
-
Harmonic emission (including at frequencies other than integer multiples of the fundamental)
-
Flicker emission
-
Switching transients
-
Frequency control
-
Protection strategies
-
Start and stop scenarios
-
Emergency scenarios
-
Generator control (active power and reactive power / voltage control)
-
Interaction between wind turbines and possible auxiliary equipment
-
Computer simulation model validation
This project is to specify functional requirements, to investigate possible technical and organisational solutions (including cost-benefit analyses), and finally to make the tender documents for the test equipment.
