Comparison of Standard Wind Turbine Models with Vendor Models for Power System Stability Analysis: Preprint

The IEC 61400-27-1 was published in February 2015. This International Standard deals with the development of generic terms and parameters to specify the electrical characteristics of wind turbines. Generic models of very complex technological systems, such as wind turbines, are thus defined based on the four common configurations available in the market. Due to its recent publication, the comparison of the response of the generic models with specific vendor models plays a key role to ensure the widespread use of this Standard. This paper compares the behaviour of a specific Gamesa dynamic wind turbine model with the corresponding generic IEC Type III wind turbine model response when the wind turbine is subjected to a three-phase voltage dip. This Type III model represents the Doubly-Fed Induction Generator (DFIG) wind turbine, which is not only one of the most commonly sold and installed technologies in the current market, but also a complex variable speed operation implementation. In fact, active and reactive power transients are observed during both fault and post-fault periods due to the voltage reduction. Hence, the boundaries of the generic models associated with transient events that cannot be represented exactly are discussed in this work.
