Parameter identification of unsymmetrical transmission lines using fault records obtained from protective relays
No full textDuring a fault, protection relays of the faulty line as well as adjacent lines react and record measurement data. The records of an adjacent healthy line can be used for line parameter identification. The special feature of the proposed method is the consideration of unsymmetrical transmission lines and the application of a high-accuracy signal modeling technique. Derived from a π line model, an estimation equation for determining the different impedances is developed. This equation contains the signal models of measurements as well as their time derivatives, which can be estimated very precisely compared to the classical approach based on filtering. By means of a simple simulation model, the accuracy of the proposed algorithm is compared to an approach previously proposed which is based on deconvolution and filtering methods as well as on the representation of a transmission line using time-varying phasors.Roberto Schulze, Peter Schegner Rastko Živanovi
Moral Good, the Beatific Vision, and God’s Kingdom Writings by Germain Grisez and Peter Ryan, S.J.. Edited by Peter J. Weigel
No full textFor close to half a century, the work of Germain Grisez has been highly influential, and his writings continue to receive considerable attention from philosophers and theologians of diverse viewpoints. His co-author for this work is the professor and noted moral theologian Fr. Peter Ryan, S.J., currently the executive director of the Secretariat of Doctrine and Canonical Affairs of the United States Conference of Catholic Bishops (USCCB). These two eminent scholars explore fundamental questions about Christian eschatology, moral theory, the purpose of human life, and the promise of human fulfilment. The authors examine Christian teaching on the final destiny of persons, investigating the meaning of God's kingdom, the hope of the beatific vision, and the centrality of moral goodness and divine grace in one's final end. This work is an ideal source for students, scholars, ministers and lay persons interested in basic questions of Christian theology, the philosophy of religion, ethical theory, and Catholic doctrin

Enhanced segmentation of disturbance records by adaptive thresholding
No full textTo analyse power system fault events captured by disturbance recorders the sampled analogue waveforms (voltages and currents) have to be segmented into system states (pre-fault, fault,...). In this paper a combination of wavelet transform (WT) and linear prediction coding (LPC) is applied to the symmetrical space phasor signals of the voltage and current waveforms. The signals obtained contain impulses when the system state changes abruptly. A threshold for segmentation is calculated using median filtering with adaptive window length. The segment borders are finally merged and validated.Stachel Philipp, Schegner Peter and Zivanovic, Rastko;http://www.pscc2008.org

Survey of harmonic current unbalance in public low voltage networks
No full textThe paper presents a survey of harmonic current unbalance in public low voltage networks based on measurements of 130 German grids. To ensure a representative set of sites, the selection is based on a classification schema that considers different consumer, generation and network configurations. New individual and aggregated harmonic unbalance indices, which have been recently introduced starting from a harmonic and interharmonic unbalance theory, are applied for the analysis. The results show that fundamental as well as harmonic currents have unbalances higher than 10% and the unbalance levels increase further with the harmonic order. Exceptional high current unbalance levels have been found in some networks with shopping centers and office buildings as unbalance issues have not been taken properly into account at the design stage. The analysis suggests that harmonic studies in public LV networks have to take into account harmonic current unbalances in order to obtain realistic results
