7. On the Identification of Embedded Generators Loss of Main Using Network Sequence Impedances Index

A. Darabi; M. Saeedi; A. Hassan Nia Khobeiri; T. Ghanbari

Volume 2, Issue 3 , Summer 2008, Pages 193-199

http://dx.doi.org/10.22061/tej.2008.1302

Abstract
  Embedded generation is a developed generation form in modern power systems. Many of embedded generators are working in parallel with the modern power networks. On the other hand, the power systems are designed based on centralized generation, not to work with embedded generators. Therefore, the embedded ...  Read More
