OPTIMAL PLACEMENT OF PHASOR MEASUREMENT UNITS ON IEEE - 24 BUS SYSTEM USING PSAT

N the present era, with the expansion of power system the complexity and challenges in terms of grid stability, security and safet y is increased. So more accurate, reliable monitoring and control systems are required. The present SCADA system is capable only to provide steady state view of the power system with high data latency whereas PMU can provide the dynamic view of power syste m. As PMU is a costly equipment so we can`t place PMUs on all buses of power system. Optimal placement of PMUs is necessary for complete observability of power system. In this paper Power System Analysis Toolbox (PSAT) is used for power system analysis and control. PSAT is used to solve the PMU placement problem using different methods such as Depth First, Annealing, Spanning Tree and Graph Theoretic procedure on IEEE - 24 bus system. The Static report provides power flow through different methods and state v ariables, total P,Q and plots of theta, frequency, voltage magnitude are calculated for IEEE - 24 bus system
