Abstract
Power quality (PQ) disturbances can have significant economic consequences for different type of customer facilities. 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 ©2004 IEEE.
