A Protection Scheme for a CORBA Environment

نویسنده

  • D. Hagimont
چکیده

Protection is a crucial aspect of computing systems, in particular when users co-operate using shared objects. Since CORBA has become a standard in the object community, designing a protection service that is well integrated within the CORBA framework is an issue of first interest. Several well defined protection models have been proposed, among which access control list based models and capability-based models, but integrating one of these protection models in a CORBA environment is still an open issue.

Protection Scheme of Power Transformer Based on Time–Frequency Analysis and KSIR-SSVM

The aim of this paper is to extend a hybrid protection plan for Power Transformer (PT) based on MRA-KSIR-SSVM. This paper offers a new scheme for protection of power transformers to distinguish internal faults from inrush currents. Some significant characteristics of differential currents in the real PT operating circumstances are extracted. In this paper, Multi Resolution Analysis (MRA) is use...

A local measurement-based protection scheme for DER integrated DC microgrid using Bagging Tree

In recent years, DC microgrid has attracted considerable attention of the research community because of the wide usage of DC power-based appliances. However, the acceptance of DC microgrid by power utilities is still limited due to the issues associated with the development of a reliable protection scheme. The high magnitude of DC fault current, its rapid rate of rising and absence of zero cros...

An Enhanced MSS-based checkpointing Scheme for Mobile Computing Environment

Mobile computing systems are made up of different components among which Mobile Support Stations (MSSs) play a key role. This paper proposes an efficient MSS-based non-blocking coordinated checkpointing scheme for mobile computing environment. In the scheme suggested nearly all aspects of checkpointing and their related overheads are forwarded to the MSSs and as a result the workload of Mobile ...

A Novel Flux-Based Protection Scheme for Power Transformers

Internal Turn-Turn faults (TTF) are the most common failures in power transformers, which could seriously reduce their life expectancy. Although common protection schemes such as current-baseddifferential protection are able to detect some of the internal faults, some other minor ones (such as TTFs andshort circuit near the neutral point) cannot be detected by such schemes. Likewise, these rela...
