This article focuses on problems and issues related to PQ and power system diagnostics, in particular those where signal processing techniques are extremely important. PQ is a general term that describes the quality of voltage and current waveforms. PQ problems include all electric power problems or disturbances in the supply system that prevent end-user(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)
The objective of this paper is to analyze and quantify the inertia and frequency responses of wind power plants with different wind turbine technologies (particularly those of fixed speed, variable slip with rotor-resistance controls, and variable speed with vector controls). The fundamental theory, the operating range, and the modifications needed for the(More)
The objective of the paper is to present an innovative method for event detection. The data is collected using a PMU network installed to provide wide-area monitoring and analysis of Texas' bulk power system. Grid events are detected using a combination of simple statstical algorithms, singular point detection with residual modeling, short time Fourier(More)
The quantity and quality of the data being captured in current power quality monitors has been increasing significantly in recent years. The availability of increasing complex and affordable VLSI components coupled with improved software methods have contributed towards these increased data rates. The user is often inundated with a tremendous amount of data(More)
ISSN 0895-0156/02/$17.00©2002 IEEE T he computer simulation of power systems has presented many challenges and opportunities over the years. Fortunately, the general nature of power systems remained relatively the same for a long period of time. This allowed power system engineers to improve modeling techniques progressively and to apply computer hardware(More)
This paper describes an efficient yet accurate methodology for estimating system damping. The proposed technique is based on linear dynamic system theory and the Hilbert damping analysis. The proposed technique requires capacitor switching waveforms only. The detected envelope of the intrinsic transient portion of the voltage waveform after capacitor bank(More)
