船舶电网谐波实时检测与补偿波形发生电路

摘要

A real-time harmonic detection and compensation waveform generation circuit is designed for the harmonic parameter measurement system in ship power network. The design applies the distributed data processing method instead of the traditional centralized data processing method,and is equipped with a Digital Signal Processor (DSP)for online measurement of harmonic parameter,which can promote the real-time data processing ability. Then,a shunt active power filter is designed in a simulation experiment platform of isolated power network with power electronic load. The experimental result shows that the de-signed real-time harmonic detection and compensation waveform generation circuit works effectively for the ship power network.%针对船舶电网谐波参数测量系统，设计电网谐波实时检测与补偿波形发生电路。该设计用分布式数据处理方法代替常规的集中式数据处理方法，采用数字信号处理器（Digital Signal Processor， DSP）进行谐波参数在线检测，提高其实时数据处理能力。在带电力电子负载的孤立电网仿真实验平台上设计一并联有源电力滤波器。实验结果表明，所设计的电网谐波实时测量与补偿波形发生电路在应用于船舶电网时能有效进行谐波检测和滤除。
