heal.abstract	This paper presents a robust method for the solution of the power system state estimation with equality constraints. The existing methods formulate coefficient matrices which are symmetric and indefinite and require factorization routines with additional logic to process the zero pivots. In this paper the formulated coefficient matrix has unique triangular factorization which can be accomplished symbolically using only the sparsity criterion. The method is illustrated with the IEEE 14-bus system. Test results are given with the FRCC 3949-bus system. © 2010 IEEE.	en
