dc.description.abstractNowadays, an environment of MEA’s distribution area has changed very much such as severe traffic jams, a high number of high constructions, and a high number of high advertising boards resulting in higher chance of overhead-transmission-line faults than the past. Some faults happen with an indistinct location, MEA has to take time to find and clear them before switching causing long outage duration especially during severe traffic jams. Consequently, MEA has created a project to build a switching-unit substation for any large customer who has a substation with one incoming line from MEA for increasing customer’s reliability and also MEA’s reliability. The switching-unit substation actually is a small-unmanned switching substation which has two incoming lines and one/two/three outgoing lines for customer substations. For fastest switching operation, the switching-unit substation have to has proper protective relays and a high-speed multistation line transfer function. The multistation line transfer function is comprised of several IEDs, communication switches and outdoor communication media, so MEA has seen a higher chance of an offline node and operational failure comparing to stand-alone substation line transfer function. The paper presents several useful techniques to implement multistation line transfer function (MLTF) with tolerance of function’s component faults resulting in the highest availability. Additional points that we have to handle are extension and maintenance issues due to changeable number of in-line substations and difficulty of wide shutdown for maintaining.
