| Abstract: | The synchronous condenser has unique advantages in such fields as improving short-circuit ratio of AC grid at receiving end,enhancing the limit power of DC transmission and stabilizing transient overvoltage and its application in UHVDC transmission project has gained again the attention of power grid enterprises.In this paper,the key parameters on improving dynamic reactive power output capability of synchronous condenser is analyzed;the configuration and control strategy of synchronous condenser at Shaoshan converter station is described.The actual operation behavior of the synchronous condenser is analyzed in detail combined with the recorded waveforms of synchronous condenser at Shaoshan converter station and the comparative simulation study.It is shown by analysis result that the synchronous condenser,in case of fault of power grid,can efficiently improve the ability of DC system to resist commutation failure.This study has a definite guiding significance in field operation and engineering application of synchronous condenser. |
