Voltage Sag in Distribution Systems- A review and comparative study (Reasons, Characteristics, Compensations and Detection)
By quick technological advancements in industrial control processes, major industries demand higher power quality. According to IEEE 1159-1995 standard, any problems in voltage, current or frequency that lead to the error or malfunctions in electrical equipment are considered as a power quality problem. Among the power quality phenomena, voltage sag has been an important problem for power sys...
متن کاملA Fast Voltage Collapse Detection and Prevention Based on Wide Area Monitoring and Control
Voltage stability is one of the most important factors in maintaining reliable operation of power systems. When a disturbance occurs in the power system, it usually causes instabilities and sometimes leads to voltage collapse (VC). To avoid such problems, a novel approach called Vector Analysis (VA) is proposed that exploits a new instability detection index to provide wide area voltage stabili...
متن کاملA robust and fast skew detection algorithm for generic documents
Abstraet--A robust and fast skew detection algorithm based on hierarchical Hough transform is proposed. It is capable of detecting the skew angle for various document images, including technical articles, postal labels, handwritten text, forms, drawings and bar codes. The algorithm is robust even when black margins introduced by photocopying are present in the image and when the document is sca...
متن کاملNew Detection of Voltage Sag Based on Phase Angle Analysis
Voltage sag compensator is very important in power quality. Its performance also depends on the types of sag detection techniques used. Sag detection technique determines the dynamic performance of a voltage-sag compensator. Many techniques have been introduced to measure and to detect voltage sag, such as RMS-Value Evaluation and Peak-Value Evaluation. Unfortunately, most of the techniques req...
متن کاملVoltage Sag Detection Method Based on Wavelet Information
Voltage sag is the major power quality problem and receives wide attention. Although wavelet analysis works well for detecting voltage sag features, the existence of noise can reduce the advantages of wavelet method or even make it ineffective. To solve the problem, the paper uses multi-scale wavelet information by multiplying the results of several scales, and then searches the local maxima fr...
