Technical efficiency and recommendations for overcurrent relay protection setting

Tác giả: Minh T.H.Q.

Abstract: Among the relay protections, overcurrent relay protections have a large proportion. To study, analyze and develop technical effect criterion for selection of overcurrent relay protection settings (high-voltage lines) and technical efficiency criterion for estimating this setting is main purpose of this paper. The probability statistical algorithms are used to calculate the above criteria. Finally base on these criteria, setting options and recommendations of overcurrent protection are given.
