Enhancing Reliability In Passive Anti-Islanding Protection Schemes For Distribution Systems With Distributed Generation, Mohsen Sheikholeslamzadeh
Enhancing Reliability In Passive Anti-Islanding Protection Schemes For Distribution Systems With Distributed Generation, Mohsen Sheikholeslamzadeh
Electronic Thesis and Dissertation Repository
This thesis introduces a new approach to enhance the reliability of conventional passive anti-islanding protection scheme in distribution systems embedding distributed generation. This approach uses an Islanding-Dedicated System (IDS) per phase which will be logically combined with the conventional scheme, either in blocking or permissive modes. Each phase IDS is designed based on data mining techniques. The use of Artificial Neural Networks (ANNs) enables to reach higher accuracy and speed among other data mining techniques. The proposed scheme is trained and tested on a practical radial distribution system with six-1.67 MW Doubly-Fed Induction Generators (DFIG-DGs) wind turbines. Various scenarios of …

Security On Medical Wireless Sensor Networks, Eric D. Southern
Electronic Thesis and Dissertation Repository
Wireless technology is fast becoming a very important tool for all aspects of communication. An area that lacks a strong implementation for wireless communication is the medical field. Wireless systems could be used by clinicians to be better able to diagnose and monitor patients. The reason behind the lack of adoption in healthcare is due to the need to meet the legislated and perceived requirements of security and privacy when dealing with clinical information. The current methods of wireless authentication are investigated and an existing issue in mobile networks is described and solved with two novel solutions; one solution within …
