基于虚拟仪器的电能质量分析仪

Power quality analyser based on virtual instrument

针对现有检测装置功能单一、数据处理能力不足等难题,本文综合各种分析方法,开发了基于虚拟仪器平台的电能质量分析仪,实现了三相谐波分析、不平衡度、电压偏差、畸变率等参数计算及在线监控、离线分析、仿真、报警一体式设计,各种分析结果以直观的图形或列表的形式给出,具有性价比高、使用方便、性能稳定、分析精度高等优点。

To overcome some disadvantages, such as inadequate capacity in data processing, single function of the current power quality monitoring devices, a power quality analyzer based on virtual instrument is designed. This system in use of many methods of power quality analysis, accomplishes the calculation of some parameters, such as harmonic analysis, degree of imbalance, voltage excursion and aberration rate. And the on-line monitoring and off-line analysis integrated with emulation and alarm system comes true. All the results show this analyzer has much excellence, such as easy to use, good performance and high-precision.
