| Abstract: | Now,China is building 7 wind power bases with the capacity over ten million kilowatts,and the large scale wind power transmission is essential due to the unbalance distribution of sources and loads.Series compensated AC transmission and high voltage DC transmission（HVDC）,as two main transmission modes,may lead to sub-synchronous oscillation when they are applied to wind power transmission.The structural characteristics of wind turbine generators were analyzed in this paper,including squirrel cage induction generator（SCIG）,doubly-fed induction generator（DFIG） and permanent magnetic synchronous generator（PMSG）.Three kinds of sub-synchronous oscillation,i.e.sub-synchronous resonance（SSR）,sub-synchronous oscillation caused by electronic devices（SSTI）,and sub-synchronous oscillation caused by controllers of wind turbines（SSCI） were clarified.In addition,the possible types of sub-synchronous oscillation for the different kinds of wind turbine generators were also discussed.Finally,the urgent problems need to be studied were analyzed as well. |
