Annotation of standard text IEC 60255-181-ed.1.0 :
IEC 60255-181:2019 specifies the minimum requirements for functional and performance evaluation of frequency protection. This document also defines how to document and publish performance test results. This document covers the functions based on frequency measurement or rate of change of frequency measurements. This document also covers frequency protection where additional blocking elements are used. This document defines the influencing factors that affect the accuracy under steady state conditions and performance characteristics during dynamic conditions. The test methodologies for verifying performance characteristics and accuracy are also included in this document. IEC 60255-181:2019 specifie les exigences minimales relatives a levaluation fonctionnelle et a levaluation de la performance des protections de frequence. Le present document definit egalement comment documenter et publier les resultats des essais de performance. Le present document couvre les fonctions basees sur la mesure de frequence ou la mesure de la derivee de frequence. Il couvre egalement la protection de frequence lorsque des elements de blocage complementaires sont utilises. Le present document definit les facteurs dinfluence qui affectent la precision dans des conditions de regime etabli et les caracteristiques de performance dans des conditions dynamiques. Les methodologies dessai pour la verification des caracteristiques de performance et de precision figurent egalement dans le present document.
