A novel approach for placement of Phasor Measurement Unit & counting their optimal number

Abstract

In India Power system monitoring is based mainly on measurements provided by Remote Terminal Unit (RTU). For power system measurement synchronized phasor or Phasor Measurement Unit (PMU) is popular choice in abroad and its popularity is increasing day by day because of its several feature. Synchrophasor technology was first introduced in india in 2011-12[7],[8],[9]. Direct measurement of voltage or current phasor is possible because of PMU which was not possible earlier. Global positioning system (GPS) provides time synchronized data. In this paper a new approach is used for optimal placement of PMU, counting their number & time elapsed. The approach is applied on IEEE-14 bus system bus system .Here all the bus which are taken into consideration is either completely observable or at some depth of un-observability is also taken into account.
