定量评价电压凹陷引起的用户损失

Quantificational Evaluating Customer Loss Caused by Voltage Sag

在电网构成存在缺陷、电压凹陷严重影响电力用户的生产生活的环境下,需要准确地衡量用电设备受影响状况以及电网用户的经济损失。该文提出用电压凹陷给用户造成的能量损失来评估用户受影响状况,并给出用户经济损失的计算方法,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。

Under the condition of the electric grid with defect and voltage sag influencing electric users on life and production seriously, it is necessary to evaluate the voltage sag influence on power consumption equipment and the customers loss accurately. This paper puts forward the assessment on the real-time operation state of the specific equipment while voltage sag happens based on the energy impact on users. Further more a method of the calculation of the customers loss is proposed. This method can provide the reference to electric utilities and users for evaluation of power quality, offering the parameter for the fact that equipment manufacturers test equipment performance.
