Frequency dependence of partial discharge initiation voltages with embedded electrodes
Partial discharge initiation voltages of a dielectric insulation material exposed to ac voltages show little dependence on frequency in the power frequency range. This results after significant voltage conditioning at the ...
Robust compensation of actively controlled bearings for a centrifugal gas compressor
Rotordynamic analysis can be substantially affected by aerodynamic loading effects which have been historically difficult to model or predict analytically. For actively controlled magnetic bearings, such model uncertainty ...
Performance Studies for a Diakoptics-based Partitioning Approach for Power System Simulation
Performance studies of partitioned power system simulations on multicore computer are presented. A partitioning approach developed by the authors was used to speed up the simulation of a shipboard power system. The system ...
Kinetic Energy Technology
The Strategic Defense Initiative Kinetic Energy Weapons (KEW) program incorporates two distinct technologies: missiles (near term) and electromagnetic launchers (long term). Since missiles already have an established ...
Voltage Standardization of DC Distribution System for Residential Buildings
The renewable energy sources (RES) such as photovoltaic (PV) are basically DC power sources. In the present scenario, the integration of RES to power distribution infrastructure necessitates the DC-AC converter. Moreover ...
Superconducting Bearing Design for Outer Rotor Flywheel Using Lumped Parameter Techniques
This paper describes the application of lumped parameter modeling techniques to designing high temperature superconducting bearings for outer-rotor flywheel energy storage systems. The lumped parameter models decrease ...
An Efficient Switch Model for Simulating Large Power Systems with Many Power Converters
Frequent matrix factorizations due to power electronic switch commutations are computationally expensive. This paper addresses this burden by treating power electronic switches as dependant sources instead of time-varying ...
