Modelling of Smart Auto-Recloser with Over Current Protection
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 7
Abstract
In a Smart Grid, one of the important aspects of a smart distribution system is the integration of smart control and protection devices. An Auto-recloser is one of the important devices in the protection system protecting the OHL (Over Head Lines) which transmit power for long distances to the loads area from the distribution panels. It was necessary to find a new smart model for the Auto-recloser device to perform developments and test new techniques for improving the protection of the distribution systems in order to face and overcome the challenges of smart grids and distributed generation integration. This paper presents an improved model of a control circuit of auto recloser which is one of the most important equipment in smart grid. The modeled control circuit is synchronized with circuit breaker in such a way that after occurrence of fault, breaker recloses automatically without any human interference. Whenever transient fault occurs in the system at distribution level, auto recloser avoids outage for longer duration. However, if the fault is persistent then auto recloser isolates only affected part in the system and avoids outage in other parts of the system. A new feature of directional over current protection is added to the control circuit of the auto recloser to overcome the new challenge of reversed current that integration of DG imposes to the traditional radial distribution systems. A simulation of a real Over Head Line (OHL) in North Delta Electricity Distribution Company having an Auto-recloser device installed on it has been done and results were discussed.
