摘要
串联型电能质量补偿器SPQC(SeriesPowerQualityCompensator)的开环结构使其补偿效果受到死区效应的影响。根据SPQC的基本工作原理和死区效应的概念,首先从理论上分析了死区效应对SPQC的影响,建立了能反映这种影响的等效电路;然后利用等效电路,计算了死区效应对SPQC补偿效果的影响。仿真结果验证了分析和结论的正确性和有效性。
The compensation performance of SPQC(Series Power Quality Compensator)is deteriorated by the dead-time effect because of its open-loop structure.Theoretical analysis of dead-time effect on SPQC is carried out based on the principle of SPQC and the concept of dead-time effect.An equivalent circuit describing the influence is constructed to calculate quantitatively the dead-time effect on SPQC.Simulative results show the validity and correctness of presented analysis and con-clusions.
