Novel Algorithms for Detection of Line Outage using PMU

The primary aim of this research work is to address the different objectives such as (i) exploitation of the AC model and development of the new objective functions (ii) utilization of current phasors exclusively instead of voltage phasors which are used by most of the existing researchers (iii) tackling of PMU outage issues (iv) incorporation of faulty PMU and measurement uncertainty into the mathematical models (v) detection of parallel line outage and (vi) ensuring the cost-effectiveness of the developed models. This entire research work is accomplished phase-wise to achieve the objectives mentioned above. Firstly the voltage phasors are used to develop the TLOD model. Secondly the current phasors are utilized to solve the transmission line outage detection (TLOD) problem. The detection of parallel line outage is also validated for the first time using current phasor based algorithms. The effectiveness and viability of the proposed TLOD algorithms have been checked on different IEEE benchmark test systems in the MATLAB environment. The performance of the proposed TLOD models has been evaluated by computing the detection accuracy (DA).
