Abstract

The classical method of power measurement of a system are iterative and bulky in nature. The new technique of measurement for bus voltage, bus current and power flow is a Phasor Measurement Unit. The classical technique and PMUs are combined with full weighted least square state estimator method of measurement will improves the accuracy of the measurement. In this paper, the method of combining Full weighted least square state estimation method and classical method incorporation with PMU for measurement of power will be investigated. Some cases are tested in view of accuracy and reliability by introducing of PMUs and their effect on variables like power flows are illustrated. The comparison of power obtained on each bus of IEEE 9 and IEEE 14 bus system will be discussed.
