摘要
提出了谐振阻抗型混合有源滤波器RITHAF与SVC结合的谐波与无功补偿的综合电能质量补偿器的电路结构,并就该综合电能质量系统的模型进行了推导.通过模型分析得出,该综合电能质量控制系统既能进行谐波治理,又能进行无功补偿.在分析模型的基础上,对晶闸管控制电抗器TCR采用电压闭环控制,而对谐振阻抗型混合有源滤波器RITHAF,结合传统滞环控制算法响应速度快和双谐振积分控制算法无稳态误差的优点,采用电流复合型滞环控制方法,利用PSCAD进行了系统仿真和实验室的实验验证.模型推导和仿真实验证明了该综合型电能质量补偿器的可行性,有较高的应用价值.
A combined harmonics and reactive power compensation circuit structure of a resonant imped- ance type hybrid active power filter （RITHAF） with injection circuit and a static Vat compensator ISVC） is proposed in this paper, which named comprehensive power quality controlling device. The model of the comprehensive power quality controlling device is educed in detail, it can be found from the model that the comprehensive power quality controlling device has the advantages of harmonic currents elimination and reactive power compensation. Based on the analysis of the model, a voltage close loop control approach was used correspond to thyristor controlled reactor （TCR） and a new complex hysteretic control method which combines the speedy performance of traditional hysteretic control with the zero steady state error of double harmonics integrators was adopted according to RITHAF. At the same time, a simulation using PSCAD and a experiment in the lab was carried out, and the feasibility of the comprehensive power quality control- ling device is verified by the model and simulation and experimental results, which has a wide use in engi- neering.
