【摘要】 随着各种敏感电力电子设备在工业中的广泛应用 ,提供高质量的电能尤为重要。威胁电能质量的主要干扰之一便是电压跌落。对电压跌落进行监测是获得电压跌落信息的直接途径。电压跌落的发生、恢复时间的精确确定是获得跌落特性参数而首先要解决的问题。实现设备运行的自动化诊断和开发电压跌落的补偿装置是解决电压跌落的最终途径更多还原

【Abstract】 With the wide application of sensitive power electronic devices in industry it is very important of provide with high quality power energy. One of the major interference to threaten the power quality is the voltage sag. Monitor of the voltage sag is a direct way to obtain the information of voltage sag. The precise decision of the time that the voltage sag occurs and recovers will be the first problem to be solve for the sag characteristic parameters. Realization of the automatic diagnosis for operation of equipment and development of the compensation device for voltage sag will be the final approach.更多还原
