摘要
针对传统电能质量分析系统存在存储容量小、显示功能单调等缺点,设计了以高性能数据采集卡PCL-818H与工业控制计算机为核心的硬件系统。该系统对实时信号进行采集与分析,并利用虚拟仪器LabW indows/CVI的强大测试分析功能,完成了基波和谐波的幅值与相位、电压偏差、有功和无功畸变率等参数计算,且具有数据存盘的软件功能。通过反复验证,该分析仪具有精度较高、直观易读、工作可靠和性价比高等特点。
To against the shortcomings of traditional power quality analyzing systems,i.e.,limited storage capacity and monotonous display functions,etc.,the hardware system combines high performance data acquisition module PCL-818H and industrial PC as the core is designed.The system can collect and analyze the real-time signals,in addition,by adopting the powerful test and analysis functions of virtual instrument LabWindows/CVI,the calculations of phases and amplitudes of fundamental wave and harmonic waves;voltage deviation,distortion rate of active power and reactive power;and software of data storage function are completed.By repeating tests,it is shown that the analyzer features high accuracy,ease to read,reliable operation and high cost effective.
