详细
On the basis of synchronized measurements of current and voltage phasors, a technique for identification of parameters of 0.4- and 6- to 10-kV lines is suggested. The technique is based on the methods of statistical processing of sets of network modes and composed of several steps. The first step is acquisition of statistical data on network modes. It involves periodic measurements of synchronized current and voltage phasors at injection nodes. The second step is direct statistical processing of the obtained information using the method of least squares. The technique was tested using a three–phase physical model of a network. The mean error of identification of resistance and reactance was approximately 0.5 and 1%, respectively.
