Hello and welcome everyone.
We are going to learn everything about the
“sub-synchronous resonance (SSR) phenomenon in doubly-fed induction generator (DFIG)-based wind farm”
Now, let me briefly introduce the contents of this course.
Given that the sub-synchronous resonance (SSR) phenomenon occurs due to the interaction between wind
turbine generators and series-compensated transmission, the series compensation is explained firstly. Where the main objective of the series compensation will be introduced. In addition, the power world simulator is utilized to validate the theoretical aspects.
Then, the problem statement of the SSR phenomenon will be introduced, where SSR definition, SSR events, SSR types, and the key factors which lead to the SSR will be investigated theoretically.
Then, the SSR modelling will be presented. Both the time-domain simulation and small signal stability are explained in detail. By the end of this section, you will be able to calculate the initial value of the state variables and extract the eigenvalue of the system at any operating point.
After that, the impact of different compensation levels, and variable wind speeds on the system stability are investigated based on the time domain simulation and eigenvalue analysis. Moreover, the effect of DFIG controllers on the system stability will be studied.
Finally, the most common methods used for damping the SSR will be introduced briefly. In addition, one of the published methods for damping the SSR will be implemented in time domain simulation and small signal stability.
