On the Definition of Software Accuracy in Redundant Measurement Systems
نویسنده
چکیده
Accuracy of measurements is defined as the sum of precision (standard deviation) and bias. Unfortunately, this definition is of little use unless bias is independently assessed. In this article, we extend this classical definition of accuracy of measurements to one of estimators obtained through data reconciliation techniques. Connection to gross error robustness measures, defined earlier by the author, is studied. © 2005 American Institute of Chemical Engineers AIChE J, 51: 1201–1206, 2005

Comparative analysis of profit between three dissimilar repairable redundant systems using supporting external device for operation
The importance in promoting, sustaining industries, manufacturing systems and economy through reliability measurement has become an area of interest. The profit of a system may be enhanced using highly reliable structural design of the system or subsystem of higher reliability. On improving the reliability and availability of a system, the production and associated profit will also increase. Re...
متن کاملStochastic-based accuracy of data reconciliation estimators for linear systems
Accuracy of an instrument has been traditionally defined as the sum of the precision and the bias. Recently, this notion was generalized to stimators [Bagajewicz, M. (2005a). On the definition of software accuracy in redundant measurement systems.AIChE Journal, 51(4), 1201–1206]. he definition was based on the maximum undetected bias and ignored the frequency of failure, thus providing an upper...
متن کاملMTBF evaluation for 2-out-of-3 redundant repairable systems with common cause and cascade failures considering fuzzy rates for failures and repair: a case study of a centrifugal water pumping system
In many cases, redundant systems are beset by both independent and dependent failures. Ignoring dependent variables in MTBF evaluation of redundant systems hastens the occurrence of failure, causing it to take place before the expected time, hence decreasing safety and creating irreversible damages. Common cause failure (CCF) and cascading failure are two varieties of dependent failures, both l...
متن کاملFault Type Estimation in Power Systems
This paper presents a novel approach for fault type estimation in power systems. The Fault type estimation is the first step to estimate instantaneous voltage, voltage sag magnitude and duration in a three-phase system at fault duration. The approach is based on time-domain state estimation where redundant measurements are available. The current based model allows a linear mapping between the m...

In this paper principles of extended Kalman filtering theory is developed and applied to simulated on-line electric power systems state estimation in order to trace the operating condition changes through the redundant and noisy measurements. Test results on IEEE 14 - bus test system are included. Three case systems are tried; through the comparing of their results, it is concluded that the pro...
