【摘要】 电压暂降能量指标对从能量角度量化设备敏感性具有重要研究意义。本文基于IEEE-1564标准对电压暂降能量指标的定义,提出了计算暂降能量的6种方法;应用实测数据进行分析比较,推荐采用半周波法计算暂降能量;针对敏感度等级不同的设备,采用考虑和不考虑过渡段的暂降能量方式衡量其敏感耐受力。更多还原

【Abstract】 The voltage sag energy index plays an important role in quantifying device sensitivity from the perspective of energy. In this paper, based on the definition of voltage sag energy index by IEEE-1564 standard, six methods for calculating sag energy are proposed. Using actual measured data for analysis and comparison, it is recommended to use semi-periodic method to calculate energy sags. For devices with different levels of sensitivity, their sensitivity tolerance is measured by taking into account the temporary energy of the transition section and not considering it.更多还原
