STUDY OF INTERACTION BETWEEN POWER SYSTEM AND VSI BASED SERIES POWER QUALITY COMPENSATOR

建立了基于电压型逆变器的串联型电能质量补偿器与系统相互作用的模型 ;在此模型的基础上 ,研究了系统和补偿器之间的相互影响 ,得出了结论 ;并用Matlab和Pspice进行了仿真验证。所得结论可为串联型补偿器参数确定提供理论依据。结论也适用于包含串联部分的统一电能质量调节器。

The interactional model has been established between power system and voltage source inverter based series power quality compensator. On the foundation of this model, the mutual influences of them have been studied and some conclusions have been drawn. The correctness of the conclusions is validated by simulation. The conclusions can provide some theoretical basis for designing of compensators and also can be applied to Unified Power Quality Conditioner, Universal Active Power Line Conditioner, and Unified Power Flow Controller.
