摘要
设计了一套功能完整的船舶电力谐波数据采集以及模拟检测系统平台,利用NI公司出产的LabVIEW软件对下位机采集卡PXIe-6358进行控制,实现实时采集数据;将数字信号转化成模拟信号,通过快速傅里叶加窗方法进行谐波检测,确保精准地检测出电力谐波量。仿真实验结果表明,该系统检测方便,精度较高,运行稳定、可靠。
A set of fully functional simulation platform on shipboard power harmonic data collection and detection was designed. Namely, lower acquisition card hardware PXIe -6358 was controlled in using LabVIEW made by NI company and data was collected in real time. Then, the digital signals were transformed into analog signals and har-monic was detected through Fast Fourier windowing method, ensuring accurately detection of the electric power har-monic content. The experimental results show that the system detection is of convenience, of high precision and of stable and reliable running.
