The conventional iteration processes of power flow measurement of a system are bulky in nature. The new technique for measurement of bus voltage and power flow is Phasor Measurement Unit. Usually, the concept of full weighted least square state estimator is a nonlinear technique, but with conventional process and PMUs it may improves the accuracy of the measurement without doing a bulky iteration procedure. In this paper the way of formation of measurement by using Full weighted least square state estimation and PMU device with conventional method will be investigated. A number of cases are tested by use of PMUs and their effect on variables accuracy on system bus current and power flows are demonstrated. The assessment of parameter obtained on IEEE 6 bus and IEEE 9 bus system will be discussed.
