摘要
分析了电力谐波对电力系统的影响以及进行谐波控制的重要意义 ,根据电子电力功率器件和控制技术的新发展 ,以数字信号处理器 (DSP)为控制核心 ,脉冲宽度调制 (PWM)回路为电流补偿执行部 ,组建了一个高速的数据采集和电流波形合成的闭环系统 。
This paper analyzes the influence of the harmonic wave in the power system and the importance of the harmonics wave control.It describes an active harmonics wave control system which is a end loop system employed DSP as the control unit and PWM loop as the current compensation implement unit,composed with high speed signal sampling and current waves synthesis.
