13、8129:2016-01 3 IntroductionChallenged with high energy costs, emission reduction demands, and increasing flexibility demands, ensuring and verifying maximum efficiency of machines and systems has become a constant struggle for owners and operators.Machines, groups of machines or industrial installat
14、ions (equipment) fulfil their tasks by employing energy conversion or energy transportation processes. The efficiency of these energy conversion and energy transportation processes is the performance of the equipment or related processes. Good performance means high efficiency and low losses. If the
15、 energy conversion process includes a thermodynamic process, especially a thermodynamic cycle process, performance monitoring can become very complex.Performance monitoring and diagnostics systems are increasingly implemented for this purpose. These are modern information systems that monitor the pr
16、ocesses of machines, groups of machines, or complete industrial installation in order to detect and localize opportunities to improve their efficiency respective performance.The benefits of performance monitoring and diagnostics lie in the provision of information (e.g. measured descriptors and expe
17、cted descriptors) regarding the current performance status of the equipment. This information is the basis to avoid non-optimal operating states, degradation processes, and to ensure early detection and quantification of deterioration processes (e.g. erosion, corrosion).Performance monitoring is oft
18、en used in addition to condition monitoring.Targets of performance monitoring and diagnostics are enhanced quality of energy conversion by achieving optimized operation, emission reduction, quantifying deterioration, recognizing faulty instrumentation, detecting defective equipment, enhanced availab
19、ility of machines, increasing efficiency, thereby reducing energy costs and costs for emissions, and improvement in internal reporting and communication by increased transparency and calculation of well-defined descriptors.Results of performance monitoring and diagnostics are addressed to operators
20、to change the operating regime in case of identified not optimal operation, and maintenance staff to repair or modify the machine or equipment in order to eliminate identified faults/deterioration.Condition monitoring and diagnostics of machines Approaches for performance diagnosisDIN ISO 18129:2016
21、-01 4 1 ScopeThis International Standard provides an introduction on how to apply performance monitoring and diagnostics for machines, groups of machines, up to complete industrial installation (equipment) typically covering the whole lifetime of the machines.This International Standard is intended
22、to introduce the terminology specifically related to performance monitoring and diagnostics of machines, describe the types of performance monitoring and diagnostics procedures and their merits, provide guidance on installation of performance monitoring and diagnostics systems, outline methods and r
23、equirements for carrying out performance monitoring and diagnostics of machines, and provide information on data interpretation, and assessment criteria and reporting requirements.This International Standard includes testing procedures for determining the accuracy of performance monitoring and diagn
24、ostics systems and procedures (including providing inputs for benchmarking the performance of equipment).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
