各种电子产品在电力系统中的大量应用使系统中谐波含量增加,谐波的产生使电能质量恶化,谐波的测量和分析是谐波治理的基础和前提。b本谐波测量系统软件在LabVIEW 7. 0上开发完成。整个程序主要由以下几个模块组成：信号发生模块、低通滤波模块、信号加窗处理模块、谐波分析模块、比例模块和记录模块.测量技术人员只要进入这个平台,通过调用控件、图标就可以轻松构建高性能的测量仪器。-Variety of electronic products in the large number of applications in power system harmonic content of the system increases the production of the harmonic power quality deterioration, harmonic measurement and analysis is the basis and prerequisite for harmonic control. b The harmonic measurement system software LabVIEW 7. 0 on developed. The whole process mainly consists of the following modules: signal module, low-pass filter module, the signal windowed processing module, harmonic analysis module, the proportion of modules and recording module. As long as the measurement of technical personnel to enter the platform, by calling the control icon easy to build high-performance measurement instruments.
