heal.abstract	Measurement system failures may cause unobservability of the power system, so that the system-state estimate cannot be obtained. The most efficient method to restore the observability of the system is to add proper pseudomeasurements to the existing measurement set. A numerical algorithm for observability restoration is proposed that is based on linear algebra and orthogonal transformations and provides a direct identification of the required pseudomeasurements. Results from several test cases on a 35-bus system are presented.	en
