Understanding power system stability
58th Annual Conference for Protective Relay Engineers, 2005., 2005This paper discusses power system instability and the importance of fast fault clearing performance to aid in reliable production of power. Explanation is provided regarding small signal stability, high impedance transmission lines, line loading, and high gain, fast acting excitation systems.

IEEE Power Engineering Society General Meeting, 2005, 2005
Power system subharmonics are considered with reference to some of their most significant effects. In particular, four kinds of sensitive electrical components are considered: lightning systems, transformers, induction motors and turbogenerators.

Electrically Powered Orthotic Systems
The Journal of Bone & Joint Surgery, 1969Electrically powered orthotic systems have been devised at Rancho Los Amigos to provide quadriplegic and other severely paralyzed patients with mobility and voluntary hand movements. The equipment necessary to fit a totally paralyzed patient for maximum restoration of upper extremity function includes an electric wheelchair, a Rancho electric arm with ...

AUTONOMOUS POWER NETWORKS BASED POWER SYSTEM
IFAC Proceedings Volumes, 2006The operation of future power systems will be more challenging and demanding than present systems owning to increased uncertainties (renewables, dispersed generation), less inertia in the system, replacement of centralized coordinating activities by decentralized parties and the reliance on dynamic markets for both power balancing and system ...

Power Systems - How Power Works in Different Systems
SSRN Electronic Journal, 2017Three major power systems are described: The ‘inclusive' totalitarian system, the ‘non-inclusive' bureaucratic system, and the ‘exclusive' plan targeting system. The totalitarian system is aiming at controlling the whole population of a social system and based on resource exploitation.

This paper describes in detail the ALMASat-1 microsatellite electrical power system, with particular emphasis to the system main components: solar panels, on-board batteries and power management board. After a brief overview of ALMASat-1 main characteristics, the power budget, is introduced showing the spacecraft “modes” defined for evaluation of the ...
