Journal ArticleDOI
Control design and dynamic performance analysis of a wind turbine-induction generator unit
E.S. Abdin,Wilsun Xu +1 more
TL;DR: In this article, a three-phase induction generator driven by a horizontal axis wind turbine and interfaced to the utility through a double overhead transmission line was presented, where the mechanical power input was controlled using the blade pitch-angle.
Journal ArticleDOI
Comparative analysis between ROCOF and vector surge relays for distributed generation applications
TL;DR: In this paper, a comprehensive comparative analysis between rate-of-change-offrequency (ROCOF) and vector-surge (VS) relays for distributed generation islanding detection is presented.
Journal ArticleDOI
A method for determining customer and utility harmonic contributions at the point of common coupling
Wilsun Xu,Yilu Liu +1 more
TL;DR: In this paper, a new method is proposed to determine the harmonic contributions of a customer at the point of common coupling, which can quantify customer and utility responsibilities for limit violations caused by either harmonic source changes or harmonic impedance changes.
Journal ArticleDOI
Test systems for harmonics modeling and simulation
R. Abu-Hashim,R. Burch,Gary W. Chang,M. Grady,E. Gunther,M. Halpin,C. Harziadonin,Y. Liu,M. Marz,T.H. Ortmeyer,V. Rajagopalan,Satish J. Ranade,Paulo F. Ribeiro,Taebo Sim,Wilsun Xu +14 more
TL;DR: In this paper, the authors present three harmonic simulation test systems for the preparation and analysis of harmonic problems through case studies and simulation examples, which can be used as benchmark for the development of new harmonic simulation methods and for the evaluation of existing harmonic analysis software.
Journal ArticleDOI
A Power Line Signaling Based Technique for Anti-Islanding Protection of Distributed Generators—Part I: Scheme and Analysis
TL;DR: In this paper, an innovative power line signaling based anti-islanding scheme was developed in response to the challenge, which broadcasts a signal from a substation to the DG sites using the distribution feeders as the signal paths.
