摘要 量化电压暂降对变频调速器的影响,有针对性地提出应对和改进措施,已成为电网公司、电力用户和制造商共同关心的重要问题。基于Part I的试验方法,该文选取中国市场上4种主流品牌变频调速器作为受试设备,通过对10 716组试验数据进行综合分析与处理,得出典型变频器耐受特性曲线。特别是,考虑到实际存在的电压暂降特征和负荷波动的随机性及不同变频调速器(ASD)产品参数分布的差异性,基于对试验数据的统计分析,量化了ASD电压暂降耐受度的不确定性,得到了模糊区域的故障概率,为用户电压暂降影响程度的量化评估、经济损失评估以及治理方案经济性分析提供参考依据。

Abstract:Quantifying the influence of voltage sags on adjustable speed drivers (ASDs) while putting forward suggestions and improvement measures has become a common concern for power grid corporations, consumers and manufacturers. In this paper, on the basis of the test method proposed in part I, four kinds of mainstream brands ASDs in our country were selected as equipment under test (EUTs). Then the typical ASD tolerance curve by comprehensively analyzing 10 716 groups of data was obtained. In particular, considering the randomness of voltage sag characteristics, load fluctuations and ASD manufacture parameters, the uncertainty of ASD tolerance curves was quantified and the fault probability of the fuzzy areas was proposed. It can provide references for quantifying the influence and economic losses of voltage sags assessment, and economic analysis of the mitigation schemes.
