IEEE recommended practice for excitation system models for power system stability studies

January 2006 (has links)
Excitation system models suitable for use in large-scale system stability studies are presented. Important limiters and supplementary controls are also included. The model structures presented are intended to facilitate the use of field test data as a means of obtaining model parameters. The models are valid for frequency deviations of ±5% from rated frequency and oscillation frequencies up to 3 Hz. / "IEEE Std 421.5 -2005 (Revision of IEEE Std 421.5-1992)."

A Framework for Assessing Cost Management System Changes: The Case of Activity-Based Costing Implementation at General Motors, 1986-1993

Anderson, Shannon W. 10 September 2002 (has links)
An opportunity to study the technical and organizational impact of management accounting system changes has emerged with companies' adoption of activity-based costing (ABC). This paper provides a structured account of experimentation with, and adoption and adaptation of ABC in General Motors Corporation, from 1986 to 1993. From this case, the paper develops a framework for evaluating ABC implementation and hypotheses about factors that influence implementation. The search for factors that ABC implementation success is guided by information technology and organizational change literature, as well as anecdotal evidence of factors that influence ABC implementation success. Data is gathered from interviews, archival records, and direct observation and the primary method of analysis is with-in case comparison of data sources. The theory of ABC implementation that emerges is one of an evolutionary sequence of implentation stages that are influenced by socio-technical factors. / The International Motor Vehicle Program at MIT

A study of rocket exhaust particles

Dennis, C. W. January 1996 (has links)
The exhaust plumes generated by rocket motors are of significant military importance for missile detection, recognition and communication due to their electromagnetic emission and propagation properties. The plume is a high temperature, high velocity stream of gas and particles, into which the surrounding air is entrained. With improvements in the modelling of plume gas chemistry and turbulence, particles present in the plume have become more important in the computational prediction of the plume's flow field, and the subsequent prediction of plume emission and propagation characteristics. This thesis describes research on plume particles, including the measurement of their physical characteristics and the addition of two phase coding (ie. particles) into current plume prediction software. Particle collections were carried out in plumes produced by rocket motors with double base and composite propellants (including aluminised). The collected particles were analysed to establish their chemical composition and size distribution. A laser Doppler anemometer system was successfully used to measure particle velocities in the plumes of 1.5kN double base motors. Particle tracking software was used to trace the paths of particles using a simplified prediction of the plume and it was found that the predicted particle behaviour was analogous to that measured experimentally. Project management software was used during the research and its relevance was assessed in respect to the project's size and nature. The management of experimental trials was studied and a methodology formulated to help improve their future operation. The costs and benefits of the research were assessed and compared to other research projects. Many of the benefits gained, such as measurement techniques, require marketing to ensure that they are exploited in the future. Recommendations for future research are given that should enhance the present work.
