摘要
提出一种利用虚拟仪器平台集成暂态电能质量扰动信号发生与检测的设计方案,在LabView环境下,按照IEEE1159—1995标准设计电压骤升、电压骤降、电压波动、瞬态震荡4种扰动信号发生器,并将希尔伯特移相法集成其中,可实现对信号发生器生成的扰动信号进行实时检测。试验用例表明,该测试平台直观、便捷,移相法对暂态扰动信号的检测准确、有效。
A transient power quality detective platform which includes the disturbance signal＇s generator and detector is designed based on virtual instrument technology. The platform is developed under LabVIEW environment. Its generator can give the transient disturbance signals according to the standard EIEE1159—1995,such as voltage swells,voltage sags,voltage fluctuation and transient oscillation. The detector uses Hilbert phase-shifting Transform method to realize the real-time detection to the disturbance signals from the generator. The test example shows that the platform for transient disturbance detection is visual and convenient,and the phase-shifting method is effective for transient power quality disturbance signal＇s detection.
