摘要
谐波是衡量电力系统供电质量的一个重要性能指标。本文提出了一种基于LabVIEW虚拟仪器开发平台的谐波检测技术,论述了谐波检测的工作原理、系统组成,利用快速傅立叶变换的谐波检测方法对谐波进行分析并给出了相应的实现方法,采用数据记录文件的数据格式实现了信号的存储及回放,运用LabVIEW中的TCP/IP开发工具包实现了数据的网络通信功能,通过仿真算例验证了设计的可行性。
Harmonic is an important performance coefficient which characterizes the power system＇s supply quality. A harmonic detection technology based on LabVIEW virtual instrument development platform is presented in this paper, in which the operational principle and the system architecture of harmonic detection are described in detail, a detailed demonstration of the harmonic detection techniques via FFT and the corresponding implementation method are made, and the realization of the signal storage and playback and the network communication function are respectively performed via data format of data log file and by using the TCP/IP SDK in the LabVIEW. The simulation results show that the scheme is feasible.
