چکیده انگلیسی
In this paper, a new method based on the properties of the Gram matrix is proposed to verify the redundancy of measurements in three-phase state estimation. The Gram matrix is constructed using rows of the measurement Jacobian matrix as vectors. The method can be used for measurement systems planning or updating of three-phase networks so that the overall system remain observable even under possible branch contingencies and loss of measurements. It is a fast and robust numerical method based on the Gram matrix factorization that is easy to implement. A small numerical example that shows the application of the method is presented.
