A novel distributed line outage detection algorithm was developed in this paper through convex relaxation and alternating direction method of multipliers (ADMM) method for smart grid system. The devised approach allows identification of multiple line outages using limited number of PMU measurements. The diagnosis procedure is performed close to the place where PMU measurements are collected and only partial variable estimates are exchanged among the neighbours of processors. It is shown that the proposed method outperforms the existing methods, which are either suffering from computational complexity or security and privacy issues. Numerical tests demonstrated the merits of the proposed schemes in co-ordinately figuring out multiple line outages in the system.
