Abstract

Transmission lines are a vital component of power system. It is used in systems with LV, HV, EHV and even more amount of voltage levels. However, sometimes lines require outage because of various reasons like maintenance or fault. Mal-operation or a small mistake during outage process can be very dangerous. Currently a process carries out outage where communication between operational engineers at two different substations plays a vital role in line outage. Miscommunication and human errors can be a threat to life of personnel involved and damage to equipments, So to ensure a proper outage process using PLC, a ladder logic is used which will check status of various equipments like circuit breakers, isolators and ground and perform sequential process of opening, isolating and grounding involved in line outage automatically. Operator now can see and check the status of whole process on SCADA screen.
