Characterization of a Large Electrical Machine Test Bench for Advanced Investigations on Wind and Hydro Generators

The acceptability and also the acceleration of renewable energy technologies is tightly linked with a better understanding of dynamic behavior of drive train components and their interactions. This ultimate understanding of system characteristics can only be achieved with comprehensive experimental investigations on different phenomena of large electrical generators. This leads consequently to a better verification of numerical and analytical models of large generators. The large generator-converter lab which is discussed in this paper is a unique opportunity for deep experimental investigations on large hydro and wind generators. It is designed to deal with the current as well as future research topics in the field of wind and hydro generators and their interactions with power electronic devices and electrical grid.
