This paper describes advances in power quality monitoring equipment and software tools for analyzing power quality measurement results. Power quality monitoring has advanced from strictly problem solving to ongoing monitoring of system performance. The increased amount of data being collected requires more advanced analysis tools. Types of power quality(More)
This paper discuses the application of the revised IEEE-519 Harmonics standards to typical industrial facilities employing adjustable speed drives (ASDs). The harmonic generation characteristics of ASDs are described. Requirements for control of the harmonic currents are developed as a function of the ASD characteristics, overall plant loading level, power(More)
An EMTP-based arc furnace model was developed for evaluation of flicker concerns associated with supplying a large integrated steel mill as they go from one to two furnace operation and as system changes are implemented that will affect the short circuit capacity at the 230 kV power supply substation. The model includes a dynamic arc representation which is(More)
Power quality monitoring has expanded from a means to investigate customer complaints to an integral part of power system performance assessments. Besides special purpose power quality monitors, power quality data are collected from many other monitoring devices on the system (intelligent relays, revenuemeters, digital fault recorders, etc.). The result is(More)
This paper presents the most significant results of a comprehensive Transient Network Analyzer study evaluating approximately 2500 MVAr of 345 kV switched capacitor banks throughout central eastern and southeastern New York. The study evaluated various concerns associated with switched shunt capacitor applications. These concerns include transient(More)
This paper studies a Fuzzy Logic Control Based (FLCB) Shunt Active Filter (SAF) capable of reducing the total harmonics distortion (THD) in Power System (PS). SAF is one of the key controllers in Flexible Alternating Current Transmission System (FACTS) to control the transmission line voltage and can be used in PS to enhance the power transmission capacity(More)
The objective of this paper is to present the modeling and analysis of a 1.7 Mva SMES-based voltage sag corrector devices. The topology of the SMES-based system and its response to an upstream fault are described. This paper details various modeling aspects of the device including methods to generate a triangular signal and an internal reference voltage.(More)
