6. Line protection and Power System Collapse
Sammanfattning : .... LÄS MER
7. Studies on the Viability of Cellular Multihop Networks with Fixed Relays
Sammanfattning : The use of low cost fixed wireless relays has been proposed as a way to deploy high data-rate networks at an affordable cost. During the last decade, significant academic and industrial research has been dedicated to relays. Protocol architectures for cellular-relaying networks are currently considered for standardization as part of both IEEE 802. LÄS MER
8. On power quality and protection
Sammanfattning : .... LÄS MER
9. Channel Estimation for Amplify and Forward Relay Networks
Sammanfattning : The use of intermediate-relaying nodes has been identified as a promising technique for enhancing coverage and combating the impairments of Multiple-Input-Multiple-Output (MIMO) wireless channels. The main ideais to introduce relays that forward the data to the destination which isotherwise out of the reach of the source. LÄS MER
10. Differential Protection for Arbitrary Three-Phase Power Transformers
Sammanfattning : This thesis describes how to provide standardized, current based, differential protection for any three-phase power transformer, including phase-shifting transformers with variable phase angle shift and transformers of all construction types and internal on-load tap-changer configurations. The use of standard transformer differential protection for such applications is considered impossible in the protective relaying standards and practices currently applied. LÄS MER
