Title

Study of PMU Technology for Power System Observability and Power System State Estimation

Abstract

Indian Grid is expanding exponentially with increased number of interconnections between Regions, leading to complexities this is the reason of necessitating dynamic monitoring of parameters. The Synchronized Grid requires moving from element oriented to Wide Area Measuring Systems. Phasor Measurement Units (PMUs) provide time synchronized phasor measurements in a power system. Synchronicity in PMU measurements is achieved by time stamping of voltage and current waveforms using a common synchronizing signal available from the global positioning system (GPS). Phasor Measurement Unit (PMU) placement at all substations allows direct measurement of the state of the network. However, PMU placement on each bus of a system is difficult to achieve either due to cost factor or due to non-existence of communication facilities in some substations, and hence there is need to optimize the placement of PMUs. There are many methods to this problem. It is possible to get multiple solutions for the same system using the same method for optimal placement. The difference lies in the percentage of sub-stations covered under double or more observability with the same number of PMUs. This paper gives a Modified Graph Theoretical Approach for optimal PMU placement problem for IEEE 14 bus system
