SSR alleviation by STATCOM in induction generator based wind farm connected to series compensated line
Bibliographic record
Abstract
In this paper, a STATCOM with voltage controller is proposed to mitigate the potential of SSR in a series compensated IG based wind farm. Detailed eigenvalue analysis is performed to demonstrate that Induction Generator effect SSR is successfully alleviated by STATCOM. The results are validated through electromagnetic transient simulation with PSCAD/EMTDC. The impacts of symmetrical fault at different locations and collector cables are investigated and the effectiveness of the proposed STATCOM controller is illustrated. It is shown that a three phase fault close to the wind farm may cause severe oscillations in the PCC voltage, electromagnetic torque and shaft torque of the wind turbine generator. To examine this situation, an equivalent circuit analysis is presented, which predicts the threshold resonant speeds within which the wind turbine becomes unstable. The study is extended to other commercially available induction generators, which also shows the potential for SSR even at realistic levels of series compensation levels, and the capability of the proposed STATCOM controller to obviate its occurrence.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
