The concept of power quality includes the quality of the supplying voltage with respect to, for instance, voltage sag, imbalance, harmonic distortion, voltage fluctuation and flicker, etc.
质量包括电源电压的质量的能力的概念与有关,例如,电压下跌,不平衡,谐波失真,电压波动并且摇曳,等等。
So this paper mostly studies the algorithm of detecting voltage sag, voltage fluctuation and flicker in power quality problems.
因此,本论文确定将电能质量问题中的电压跌落和电压波动及闪变现象作为主要研究对象。
This method can provide the reference for electric utilities and users for evaluation of power quality, offering the economic parameters to evaluate voltage sag under electric markets environment.
该方法可作为电力公司和用户评价电能质量的参考,并为电力市场环境下合理评价电压凹陷提供了经济指标。
