摘要
针对电力系统谐波的诸多危害,谐波检测为谐波的有效治理提供了依据。传统的谐波参数检测方法通常以硬件为核心,无法与谐波检测领域的发展趋势同步。计算机技术、通信技术以及测试测量技术的不断发展,推动了虚拟仪器技术的进步,将虚拟仪器技术的测试方法引入到谐波检测中可以为相关领域的研究提供一定的参考。文中重点介绍在虚拟仪器平台LabVIEW环境下所开发的一种新的谐波检测分析系统,该系统通过调用动态链接库的驱动程序,实现LabVIEW与普通数据采集卡的连接和控制。测试功能部分主要设计了电能参数和谐波的相关测量分析。仿真结果表明,该系统可有效完成电压稳态谐波的测量分析以及对信号突变点的检测识别,测量精度相对较高,为虚拟仪器在谐波检测领域的广泛应用提供了可靠依据。
In view of many hazards of harmonics in power system,harmonic detection provides a basis for effective harmonic control.Some traditional harmonic parameter detection methods usually take hardware as the core,and gradually can not keep pace with the development trend in the field of harmonic detection.The continuous development of computer technology,communication technology and test and measurement technology promotes the progress of virtual instrument technology.Introducing the test method using virtual instrument technology into harmonic detection can provide some reference for related fields.This paper focuses on a new virtual harmonic detection and analysis system developed under the environment of virtual instrument platform LabVIEW.The system realizes the connection and control between LabVIEW and ordinary data acquisition card by calling the driver of dynamic link library.The test function part is mainly designed to complete the measurement and analysis of power parameters and harmonics.The simulation results show that the system can effectively complete the measurement and analysis of voltage steady⁃state harmonics and the detection and identification of signal mutation points.The measurement accuracy is relatively high,which provides a reliable basis for the wide application of virtual instrument in the field of harmonic detection.
