摘　　要：液流电池储能电站应用了大量的双向储能变流器、变频器和动力不间断电源装置,这些电力电子装置运行时会产生谐波电流。通过ETAP建立分析模型,对谐波进行分析与研究,计算母线电压畸变率和回路电流畸变率,提出在电压畸变率超标的母线段设置有源电力滤波器用于补偿谐波电流,达到抑制谐波的目的。A large number of power conversion system,frequency variable driver,and uninterrupted power supply are employed in energy storage power station adopted liquid flow redox cell,these electric apparatuses generate harmonic current while working.An analytical model is established through ETAP.The harmonics are analyzed and studied,and the bus voltage distortion rate and loop current distortion rate are calculated.It is proposed to set an active power filter in the bus section where the voltage distortion rate exceeds the standard,so as to achieve the purpose of harmonic suppression.
