Computer control of power systems requires evaluation of uncertainties in analog measurements and their reduction to a level that allows satisfactory control. In this paper a range of measurements is obtained from a substation to span peak- and light-load conditions and to include bus voltages, phase angles and line flows. Then the redundancies in measurements are used to formulate several functions relating these measurements with their attending errors. Minimization of these functions have yielded the required corrective coefficients. 6 refs., 1 fig., 6 tabs.
