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.

Key words： Adjust speed driver voltage sag test method tolerance curve fuzzy region probability model
