OPTIMAL REPAIR AND PLACEMENT OF PHASOR MEASUREMENT UNITS ON POWER SYSTEMS

Abstract

This paper determines optimal repair rates of components of phasor measurement unit (PMU) installed in a power system, under the budgetary constraint. Based on optimal repair rates of components of PMU; we determine the reliability of PMU, the reliability of observability of buses falling within the scope of PMU, the reliability of observability of complete power system and optimal number of PMUs and their candidate buses on a power system to achieve the targeted reliability of observability of complete power system.
