摘　　要：根据电能质量检测技术的现状及传统电能质量分析仪存在的问题,设计一种基于虚拟仪器LabVIEW的新型电能质量检测系统,实现对电网的谐波分析、不平衡度、畸变率、频率偏差等参数计算、报警和仿真,应用虚拟仪器和网络技术的结合对电能质量指标进行在线监测并将监测得到的数据通过网络传输至客户端,设计一种基于LabVIEW的电能质量远程监测系统,该方法与传统方法相比,其开发效率、性价比、可操作性及可维护性等方面都具有明显优势。Because of present situation of power quality monitoring and the problems in traditional power quality analysis instruments, a novel power quality automatic monitoring system based on virtual instrument technology in Lab VIEW environment was designed. The designed system can evaluate the grid harmonic and realize the calculation, alert and simulation of the unbalance factor, total harmonic distortion, frequency deviation and other parameters. The index data can be obtained on line and transferred to the clients via internet by virtual instrument and internet technology. Compared with the traditional monitoring ways, the proposed system has better efficient,cost performance,operability and maintainability.
