Download or read book Characterization and Survey of Automated Fault Detection and Diagnostics Tools written by and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that 5%-30% of the energy used in commercial buildings is wasted due to faults and errors in the operation of the control system. Tools that are able to automatically identify and isolate these faults offer the potential to greatly improve performance, and to do so cost effectively. This document characterizes the diverse landscape of these automated fault detection and diagnostic (AFDD) technologies, according to a common framework that captures key distinguishing features and core elements. To understand the diversity of technologies that provide AFDD, a framework was developed to capture key elements to distinguish the functionality and potential application of one offering from another. The AFDD characterization framework was applied to 14 currently available technologies, comprising a sample of market offerings. These 14 technologies largely represent solutions that integrate with building automation systems, that use temporary in field measurements, or that are implemented as retrofit add-ons to existing equipment. To characterize them, publicly available information was gathered from product brochures and websites, and from technical papers. Additional information was acquired through interviews and surveys with the developers of each AFDD tool. The study concludes with a discussion of technology gaps, needs for the commercial sector, and promising areas for future development.
Download or read book Optimal Automated Process Fault Analysis written by Richard J. Fickelscherer and published by John Wiley & Sons. This book was released on 2012-11-27 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tested and proven strategy to develop optimal automated process fault analyzers Process fault analyzers monitor process operations in order to identify the underlying causes of operational problems. Several diagnostic strategies exist for automating process fault analysis; however, automated fault analysis is still not widely used within the processing industries due to problems of cost and performance as well as the difficulty of modeling process behavior at needed levels of detail. In response, this book presents the method of minimal evidence (MOME), a model-based diagnostic strategy that facilitates the development and implementation of optimal automated process fault analyzers. MOME was created at the University of Delaware by the researchers who developed the FALCON system, a real-time, online process fault analyzer. The authors demonstrate how MOME is used to diagnose single and multiple fault situations, determine the strategic placement of process sensors, and distribute fault analyzers within large processing systems. Optimal Automated Process Fault Analysis begins by exploring the need to automate process fault analysis. Next, the book examines: Logic of model-based reasoning as used in MOME MOME logic for performing single and multiple fault diagnoses Fuzzy logic algorithms for automating MOME Distributing process fault analyzers throughout large processing systems Virtual SPC analysis and its use in FALCONEERTM IV Process state transition logic and its use in FALCONEERTM IV The book concludes with a summary of the lessons learned by employing FALCONEERTM IV in actual process applications, including the benefits of "intelligent supervision" of process operations. With this book as their guide, readers have a powerful new tool for ensuring the safety and reliability of any chemical processing system.

Download or read book Automated Fault Diagnostics for Frequency dependent Circuits by Correlation and Variance Techniques written by Henry B. Metcalf and published by . This book was released on 1970 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer program, NASAP (Network Analysis for Systems Applications Program), has been adapted to perform fault diagnosis in frequency-dependent systems. The program simulates a short circuit and an open circuit for each network parameter and prints out a modified transfer function of the network corresponding to each simulated failure. Experimental and simulated data are subjected to correlation and variance analysis in order to rank all parameters according to probability of failure in the network model. The program lists, at present, single failures in order to decreasing probability. Possible extensions of the program to multiple failures are examined.

Download or read book Fault Diagnosis Systems written by Rolf Isermann and published by Springer Science & Business Media. This book was released on 2006-01-16 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: With increasing demands for efficiency and product quality plus progress in the integration of automatic control systems in high-cost mechatronic and safety-critical processes, the field of supervision (or monitoring), fault detection and fault diagnosis plays an important role. The book gives an introduction into advanced methods of fault detection and diagnosis (FDD). After definitions of important terms, it considers the reliability, availability, safety and systems integrity of technical processes. Then fault-detection methods for single signals without models such as limit and trend checking and with harmonic and stochastic models, such as Fourier analysis, correlation and wavelets are treated. This is followed by fault detection with process models using the relationships between signals such as parameter estimation, parity equations, observers and principal component analysis. The treated fault-diagnosis methods include classification methods from Bayes classification to neural networks with decision trees and inference methods from approximate reasoning with fuzzy logic to hybrid fuzzy-neuro systems. Several practical examples for fault detection and diagnosis of DC motor drives, a centrifugal pump, automotive suspension and tire demonstrate applications.

Download or read book Data Driven Fault Detection for Industrial Processes written by Zhiwen Chen and published by Springer. This book was released on 2017-01-02 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zhiwen Chen aims to develop advanced fault detection (FD) methods for the monitoring of industrial processes. With the ever increasing demands on reliability and safety in industrial processes, fault detection has become an important issue. Although the model-based fault detection theory has been well studied in the past decades, its applications are limited to large-scale industrial processes because it is difficult to build accurate models. Furthermore, motivated by the limitations of existing data-driven FD methods, novel canonical correlation analysis (CCA) and projection-based methods are proposed from the perspectives of process input and output data, less engineering effort and wide application scope. For performance evaluation of FD methods, a new index is also developed.
Download or read book Using Metering to Perform Energy Management written by George “Buster” Barksdale and published by CRC Press. This book was released on 2024-04-12 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers many helpful analysis tools and processes to assist energy managers (EMs) administer their energy program through their meter management system (MMS). These tools and the corresponding techniques offer opportunities for the EM to optimize their time. If fully utilized, the MMS will allow an EM to reduce field time significantly, as they can perform most of the energy management pre-analysis, benchmarking, data analysis and, in many cases, complete the task of performing a virtual audit remotely from their office. The book covers many instructional areas that are, for the most part, only offered by consulting groups and software vendors as services. Those two groups offer their services for fees and therefore do not publish their ideas or best practices for commercial use. Software vendors provide software analytics whose functional aspects are addressed by our descriptions of the essential tasks in each chapter. This book allows EMs to expand their knowledge of software capabilities by viewing other best practices. Consulting groups offer services in a few areas: basic benchmarking and monitoring-based commissioning (MBCx). These services are considered essential to energy management but are generally implemented as on-site services, which, due to their nature, are much more expensive than a monitoring commissioning (MCx) solution. Monitoring commissioning, in contrast to MBCx, is purely done at the monitoring level and allows you to manage the critical energy measures that comprise the majority of the savings, but without getting into the field testing. Benchmarking is covered much deeper in the book as we show how to benchmark each system within a building. The benchmarking sections show how to automatically analyze each system’s usage into a separate benchmark for baseload, lighting, AC, and fan/pump systems. These systems produce benchmarks so EMs can compare by site, category type, climate zone, etc. We also introduce benchmarks that enable the EM to utilize tools to determine the performance of each system and which are their most significant energy users. These analytics functions are covered to produce results that identify potential energy savings for each energy system.
Download or read book Automatic Fault Characterization Via Abnormality Enhanced Classification written by and published by . This book was released on 2010 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enterprise and high-performance computing systems are growing extremely large and complex, employing hundreds to hundreds of thousands of processors and software/hardware stacks built by many people across many organizations. As the growing scale of these machines increases the frequency of faults, system complexity makes these faults difficult to detect and to diagnose. Current system management techniques, which focus primarily on efficient data access and query mechanisms, require system administrators to examine the behavior of various system services manually. Growing system complexity is making this manual process unmanageable: administrators require more effective management tools that can detect faults and help to identify their root causes. System administrators need timely notification when a fault is manifested that includes the type of fault, the time period in which it occurred and the processor on which it originated. Statistical modeling approaches can accurately characterize system behavior. However, the complex effects of system faults make these tools difficult to apply effectively. This paper investigates the application of classification and clustering algorithms to fault detection and characterization. We show experimentally that naively applying these methods achieves poor accuracy. Further, we design novel techniques that combine classification algorithms with information on the abnormality of application behavior to improve detection and characterization accuracy. Our experiments demonstrate that these techniques can detect and characterize faults with 65% accuracy, compared to just 5% accuracy for naive approaches.
