Principle and Design of Integrated All Frequency Protection for Half-wavelength AC Transmission Lines
Abstract
This paper presents a protection technique, named integrated all frequency protection, and put forward a design of this protection technique for half-wavelength AC transmission line. In this design, the integrated all frequency protection detects the frequency signals from measured wideband signals when faults occurred, and perform calculations based on the algorithms which integrate conventional power frequency protection algorithms and transient based protection algorithms. In this paper, the adaptabilities on half-wavelength AC transmission line of each mentioned protection algorithms have been analyzed, a coordination scheme has been designed based on the results, in which the algorithms are grouped into three operating groups: single-ended, multi-ended and backup protections, all of the protections complement each other, and implement the function of instant trip, accelerate trip and backup protection. The scheme provides an effective solution for the protection of half-wavelength AC transmission line.
