摘要
针对目前电力系统对电网电能质量和电网测控自动化的要求,开发了基于虚拟仪器的三相多功能电能参数测试系统。重点阐述了系统的软硬件组成、设计思想及其工作流程,比较了国内外电压、电流、频率、功率、谐波等电能参数的各种测量方法并说明了本系统所采用的方法及其优点。最后给出了谐波测量的仿真结果并简要说明本系统的应用前景。
To meet the demand of power-supply monitoring and electric network automation,the authors have developed the measurement system for three-phase electric energy parameters based on virtual instrument.The software & hardware construction,design concept and working flow are mostly detailed. The authors compare the method at home and aboard measuring power parameters which include voltage,current,frequency,power,harmonic and so on,explain why this system adopts the method and the reason.Finally,the paper gives emulation results of harmonic measurement and briefly introduces the occasion when this system can be used.
