Abstract

Power quality (PQ) disturbances can have significant economic consequences for different type of customer faculties. Voltage sags are the most common power quality disturbances causing disruption of consumer equipment. The paper therefore, focuses on voltage sags and discusses economic assessment of power quality. By combining the probabilistic assessment of voltage sags with the voltage tolerance curves of electrical equipment an estimate can be made of the sag events responsible for tripping of the equipment over a specified period of time. If the tripping costs per event of the equipment are available, the assessment of customer financial losses due to the inadequate quality of supply can be made. The effect of sensitive load composition, i.e., type of the industrial process on the customer financial losses (damage costs) due to expected voltage sags at a bus has been investigated in the paper. This approach can be used as a tool to select the most favorable location in the network to connect an industrial plant having particular composition of sensitive equipment.

工艺设备组成对电压跌落造成的经济损失的影响

电能质量(PQ)扰动会对不同类型的用户系统造成严重的经济后果。电压跌落是引起消费者设备中断的最常见的电能质量干扰。因此，本文将重点研究电压跌落问题，并讨论电能质量的经济评价。通过将电压跌落的概率评估与电气设备的电压容限曲线相结合，可以估计出在规定时间内导致设备跳闸的电压跌落事件。如果可以获得设备每次事故的起下钻成本，就可以评估由于供应质量不足而造成的客户经济损失。本文研究了敏感负载组成的影响，即工业过程的类型对客户经济损失(损坏成本)的影响，这些损失是由于总线上预期的电压骤降造成的。这种方法可以作为一种工具，在网络中选择最有利的位置来连接具有特定敏感设备组成的工业厂房。
