本文提出了一种具有谐波治理和无功补偿连续可调优点的并联型高电能质量调节装置，该装置主电路由晶闸管控制电抗器TCR和谐振阻抗型混合有源滤波器RITHAF组成，其中，RITHAF无源部分PF提供的固定容性无功与TCR提供的可调感性无功综合，实现快速可调连续无功补偿，同时RITHAF又能对谐波进行治理，可提高电能质量和功率因数。在分析该装置结构的基础上，就谐波域和基波域进行了模型推导，并对该装置运行时的控制方法进行了研究，模型推导和仿真实验证明了该装置的可行性。

Development of a Shunt Type of High Power Quality Regulating Device

A shunt type of high power quality regulating device of harmonics eliminating and reactive power compensation regulating continuously is proposed , which composed by thyristor controlled reactors(TCR) and resonant impedance type hybrid active filter(RITHAF).Regulating reactive power can be compensated quickly because of the regulating inductive reactive power supplied by TCR and the fixed capacitor reactive power supplied by the passive filter (PF) of RITHAF while eliminate the harmonics, raise power quality and power factor. Based on the analysis of the structure of device, the model of the system from harmonics field and fundamental field, and the control method of the device is presented in detail .The feasibility of the shunt type of high power quality regulating device is verified by the model and simulation results.
