摘要
基于集成门极换向晶闸管(integrated gate commutated thyristor,IGCT)和链式逆变器的±50Mvar静止同步补偿器(static synchronous compensator,STATCOM)已研制完成并投入工业运行。文中给出了±50Mvar STATCOM的主电路构成及主要参数、150Hz优化脉宽调制(pulse width modulation,PWM)控制策略、直流电压平衡控制策略及自平衡反馈线性化无功控制策略,并给出了现场的试验结果。试验结果表明±50Mvar STATCOM装置的各项性能指标都达到了预期目标。
The ±50 Mvar STATCOM based on chain circuit converter employing IGCTs has been developed successfully and has been put into operation. The main circuit configuration and parameters, the 150Hz optimal PWM （pulse width modulation） control scheme, the DC voltage balance control scheme, the var control scheme based on linearization via feedback and the field test results are given in this paper. Field test results confirmed that all performance requirements were met.
