Existing standards use information of the residual voltage magnitude and duration to characterize voltage dips severity. In reality, these two-dimensions of voltage dips may not always indicate the actual impact on customers and the published indices can lead to misleading information. This paper describes a new approach of estimating the impact of voltage dips on aggregated customers and the correlation...
The economic loss of an industrial customer due to a voltage dip depends on the impact of the dip on the customer that is expressed relative to the process interruption as the base. The relative impact may vary depending on the severity of voltage dips and sensitivity of the process to the dips. In this paper, a method for determining weighting factors of various types of dips having different magnitudes...
The objective of this preliminary study was to investigate if voltage dips induced by different root causes have specific time-frequency patterns in their respective voltage dip waveforms by which the underlying root cause can be uniquely identified. Finding specific frequency patterns in the voltage dip waveform provides an innovative basis for the automatic classification of voltage dips based on...
A voltage dip is an important power quality (PQ) disturbance mainly caused by short-circuit faults. It can cause malfunctioning of sensitive equipment that can lead to the disruption of industrial processes, which usually results in substantial financial losses. One way to solve the problems caused by voltage dips is to identify the weak parts of a process and make the manufacturing process more robust...
Voltage dips constitute to a noticeable part of power quality (PQ) problems but causing major financial losses to industrial and commercial customers. This work involves comparative studies to choose the most appropriate location of monitoring dips for regulation. In this paper, a Dutch MV network is used and dip monitoring locations are considered at different points of connections (POC) where customers...
