Leasecraft Power System Leasecraft Power System
IEEE Transactions on Aerospace and Electronic Systems, 1985Various building blocks of the Fairchild Leasecraft Power System are described in detail after a brief description of the evolution of the Leasecraft spacecraft. The principle of maximum power transfer from a solar cell array has been employed in the power system advantageously.

A fuzzy inference system for power systems
2017 IEEE 3rd International Forum on Research and Technologies for Society and Industry (RTSI), 2017The amount of data available on the industrial plants has seen an exponential growth in the last few years. One of the greatest player in this trend has been the technological progress that has made also cheap devices smart. Thus, also the low voltage (LV) circuit breaker (CB) becomes an acquisition system able to communicate data to the cloud. Because

Multiprocessor System for Power System Analysis
IFAC Proceedings Volumes, 1981Abstract As the technology of computer hardware advances, the speedup of power system analysis becomes more and more necessary. In order to study about future power system analysis by parallel processing, we made a prototype of a multiprocessor system.

On the number of system separations in power system
2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015Power systems subjected to large disturbances may become transiently unstable, which can lead to uncontrolled system separation and cascading outages. An important goal of developing the smart grids is to maintain high-level system stability. Controlled islanding is a corrective measure that can efficiently attenuate the detrimental impact of large ...

Power Spectrum of the Respiratory System
Biometrics, 1976Spectrum analysis is proposed as a method for analyzing biologic time series data that arise in the study of respiration. A mechanical model of the respiratory system is used to provide a theoretical basis for the interpretation of the air flow spectrum in terms of a physically defined energy concept.

HYPERCHAOS IN A SPACECRAFT POWER SYSTEM
International Journal of Bifurcation and Chaos, 2011This paper presents some rigorous arguments on a chaotic strange attractor in a spacecraft power system, which is a 3D system with hysteresis switching. By carefully picking a suitable cross-section with respect to the attractor, we find a topological horseshoe of the corresponding third-returned Poincaré map, thus giving a rigorous verification of ...

Power System Stabilizers Design for Interconnected Power Systems
IEEE Transactions on Power Systems, 2010This paper proposes a method of designing fixed parameter decentralized power system stabilizers (PSS) for interconnected multi-machine power systems. Conventional design technique using a single machine infinite bus approximation involves the frequency response estimation called the GEP(s) between the AVR input and the resultant electrical torque ...
