heal.abstract	This paper presents a method for analog and topological measurement error identification in generalized state estimation. Errors of analog measurements depend on measurement equipment accuracy. Errors of topological measurements (switching device statuses) result in erroneous network models. In generalized state estimation, analog and topological data are processed as a single interacting information set. The conventional measurement model is extended by incorporating the breaker statuses (open or closed) and the active and reactive power flows as continuous state variables. Depending on breaker statuses, additional pseudomeasurements are introduced. The method treats the analog and status measurements as regular measurements. Hypothesis testing for detection and identification of bad analog and topological measurements is used (J((x) over cap) and (r) over cap (N), test respectively). Test results for the RTS substation system are reported. (c) 2004 Elsevier B.V. All rights reserved.	en
