Analysis and Countermeasures Proposal of a Case of Subsynchronous Oscillation in an Actual Wind Farm
The present work originated from the repeatedly events of subsynchronous oscillation encountered by an actual wind farm.It first carried out information collection and power quality test on the wind farm and found out the causes of subsynchronous oscillation.Consequently it further studied universally the underlying mechanism of wind farm subsyn-chronous oscillation through time-domain simulation and actual-data-based verification,and also tentatively formulated the specific countermeasures.This work may provide useful information for suppressing subsynchronous oscillation and impro-ving power supply quality in grids integrated with large-scale wind generations.
