摘要
为了解决谐波和无功功率等电能质量问题对冶金系统的影响,本文采用基于DSP+CPLD全数字控制的并联型有源电力滤波器(APF)来实现补偿。本文分析了APF的等值电路、系统结构及工作原理,并进行控制系统的硬件设计。仿真和实验结果表明,该补偿装置可以对谐波和无功功率进行有效地补偿。
In order to solve power quality issue( such as harmonic,reactive power)in metallurgy system , a fullydigital - controlled shunt active power filter based on DSP and CPLD for three - phase four - wire power system is studied and designed in this paper. The equivalence circuit,operation principle and structure of a active power filter is analyzed, and the hardware of control system is optimization designed . The simulation and experiment results show that the harmonic and reactive power currents can be compensated efficiently by this equipment.
