摘要
为解决铝厂的谐波和无功等电能质量问题,本文提出一种大容量有源滤波和无功补偿装置,通过APF与TSC的并联,达到抑制谐波分量和在大容量负载下动态连续补偿无功分量的目的。本文分析了该装置的结构和工作原理,具体阐述了并联型有源电力滤波器的工作原理和TSC无功补偿原理,提出了由电压外环、电流内环控制的双闭环策略,保证系统有源滤波器的直流侧电压稳定,实现谐波抑制,达到连续无功补偿的目标,最终结果符合要求。
For solving such power quality problem as harmonic and reactive power of the aluminum factory,in this paper,a large capacity active power filter harmonic and reactive power compensation device is raised to suppress the harmonic component in large capacity under load dynamic compensation of reactive component objective through parallel connection of APF and TSC.Both the structure and working principle of the device is analyzed,the working principle of parallel type reactive power filter and reactive compensation principle of TSC are specifically introduced,and such double looped ring strategy controlled by external ring of voltage and internal ring of current is proposed,thus assuring stable voltage at DC side of active filter,achieving harmonic suppression and sustaining reactive compensation.And the final result complies with requirement.
