Optimal placement of PMUs & analytics on PMU data using ANN technique

Power system play a vital role in human life. The reliability of these power systems depends on the operating constraints & conditions. PMU (Phasor measurement units) utilizes synchronization signals provided by the GPS (global positioning system) satellites and deliver the voltage and currents phasors measured at a given node. To avoid the redundant use of PMUs, the optimal locations for the PMUs must be determined. The main objective of this research paper is to place a minimal number of PMUs, so that the system can be effectively observable & the implementation for on-line estimation of the power system and for security monitoring. The ANN technique utilizes synchrophasor is to carry out the contingency analysis by calculating the sensitivity factors. The same thing is verified with the help of Fast Decoupled Load Flow (FDLF), in MATLAB environment and contingency ranking is made. This method is very much effective in ranking the contingencies of a electrical power system. This was tried on IEEE-14 Bus system & the results were found to be effective.
