Effect of Remote Back-Up Protection System Failure on the Optimum Routine Test Time Interval of Power System Protection
Appropriate operation of protection system is one of the effective factors to have a desirable reliability in power systems, which vitally needs routine test of protection system. Precise determination of optimum routine test time interval (ORTTI) plays a vital role in predicting the maintenance costs of protection system. In the most previous studies, ORTTI has been determined while remote bac...
متن کاملA Novel Flux-Based Protection Scheme for Power Transformers
Internal Turn-Turn faults (TTF) are the most common failures in power transformers, which could seriously reduce their life expectancy. Although common protection schemes such as current-baseddifferential protection are able to detect some of the internal faults, some other minor ones (such as TTFs andshort circuit near the neutral point) cannot be detected by such schemes. Likewise, these rela...
متن کاملProtection Scheme of Power Transformer Based on Time–Frequency Analysis and KSIR-SSVM
The aim of this paper is to extend a hybrid protection plan for Power Transformer (PT) based on MRA-KSIR-SSVM. This paper offers a new scheme for protection of power transformers to distinguish internal faults from inrush currents. Some significant characteristics of differential currents in the real PT operating circumstances are extracted. In this paper, Multi Resolution Analysis (MRA) is use...

متن کاملDiagnosis of Power System Protection
Power systems are naturally exposed to several fault conditions, namely short-circuits. Automatic protection and control systems are responsible for selective tripping of faulted devices and their subsequent reconnection. An application to automatically diagnosing abnormal conditions in power distribution network substations is described in this work. It is based on a model of the power network...
