摘要
针对传统的电力系统谐波测试仪器操作复杂,性能低等问题,本文将虚拟仪器技术应用于电力系统谐波测试。通过使用美国NI公司功能强大的LabVIEW虚拟仪器开发平台研制了基于虚拟仪器技术的电力谐波测试仪,该仪器具有结构简单,扩展性能好,测试精度高等优点。文章详细的描述了谐波测试仪设计中的技术要点及工作原理,并给出了仪器的操作界面。通过样机测试,各项指标均达到设计要求,具有很大的市场价值。
To solve the problems of the complicated operation and low performance,a scheme that the virtual instrument(Ⅵ) technology is applied to the harmonics testing instrument design.On the development platform of LabVIEW of Nation Instrument,A harmonics meter based onⅥis developed.The instrument has a simple structure, scalability,and high precision test.This paper introduces the main technologies and the working principle of this system and the operating Interface is given.Testing data of experimental prototype can meet the design targets.It has great practical value.
