Special Issue Information

Dear Colleagues,

In order to ensure the safety and reliability of power and energy systems, including wind turbines, gas/steam turbines, power plants, etc., failure mechanism, reliability assessment, prognostics, and health management (PHM) have becoming recent developments in integrity analysis of these systems. For many countries, such as the European countries, England and the USA, currently facing a potential future mismatch from energy production and transformation, currently increasing interests are being paid on new techniques to discover and understand the remaining life and integrity assessment of power and energy systems.

To prevent any unexpected machine breakdowns and accidents, early faults of critical components in these systems should be detected as soon as possible. Once early faults of critical components are diagnosed, their performance degradation assessment and remaining useful life estimation should be conducted to maximize lifetime of power and energy systems. Moreover, due to unexpected ageing related degradations/damaging, mechanical properties, microstructures and structural resistance of systems/components often require stochastic considerations related to failure mechanism modeling and analysis. In addition, various sources of uncertainty/variability arising from a simplified representation of the actual physical process (often through semi-empirical or empirical models) and/or sparse information on manufacturing, material properties, and loading profiles contribute to stochastic behavior under operation.

Accordingly, continued improvements on PHM have been possible through advanced signature analysis, performance degradation assessment, as well as accurate modeling of failure mechanisms by introducing advanced mathematical approaches/tools. Through combining the deterministic and probabilistic modeling techniques, researches on PHM and structural health monitoring (SHM) can provide assurance for new structures at the design stage and ensure the integrity in the construction at the fabrication phase. Specifically, power and energy system failure occurs under multi-sources of uncertainty/variability, resulting from load variation in usages, material properties, geometry variations within tolerances, and other uncontrolled variations. Thus, advanced methods and applications for theoretical, numerical, and experimental contributions that address these issues on PHM are desired and expected, which attempts to prevent over-design and unnecessary inspection and provide the tools to enable a balance between safety and economy to be achieved.

The aim of this Special Issue would be to provide the data, models and tools necessary to performing PHM from structural to the system, resulting in the use of advanced mathematical, numerical and experimental techniques. Therefore, researchers are invited to provide original research and review articles that seek for accurate and efficient machine fault diagnosis and prognosis, remaining life assessment, condition-based maintenance, and so forth. Potential topics include, but are not limited to:

  • wind/gas/steam turbine technologies
  • power plant technologies
  • failure mechanisms
  • damage/degradation
  • digital/adaptive signal processing
  • statistical signal processing
  • prognostics and health management
  • probabilistic damage tolerance
  • probabilistic physics of failure
  • structural integrity assessment
  • structural reliability
  • reliability testing and statistics
  • life prediction
  • degradation modeling and analysis
  • structural health monitoring
  • system diagnostics

Techno-economic assessments (TEA) of biodiesel production may comply with various economic and technical uncertainties during the lifespan of the project, resulting in the variation of many parameters associated with biodiesel production, including price of biodiesel, feedstock price, and rate of interest. Engineers may only collect very limited information on these uncertain parameters such as their variation intervals with lower and upper bound. This paper proposes a novel non-probabilistic strategy for uncertainty analysis (UA) in the TEA of biodiesel production with interval parameters, and non-probabilistic reliability index (NPRI) is employed to measure the economically feasible extent of biodiesel production. A sensitivity analysis (SA) indicator is proposed to assess the sensitivity of NPRI with regard to an individual uncertain interval parameter. The optimization method is utilized to solve NPRI and SA. Results show that NPRI in the focused biodiesel production of interest is 0.1211, and price of biodiesel, price of feedstock, and cost of operating can considerably affect TEA of biodiesel production.

As the main power source for aircrafts, the reliability of an aero engine is critical for ensuring the safety of aircrafts. Prognostics and health management (PHM) on an aero engine can not only improve its safety, maintenance strategy and availability, but also reduce its operation and maintenance costs. Residual useful life (RUL) estimation is a key technology in the research of PHM. According to monitored performance data from the engine’s different positions, how to estimate RUL of an aircraft engine by utilizing these data is a challenge for ensuring the engine integrity and safety. In this paper, a framework for RUL estimation of an aircraft engine is proposed by using the whole lifecycle data and performance-deteriorated parameter data without failures based on the theory of similarity and supporting vector machine (SVM). Moreover, a new state of health indicator is introduced for the aircraft engine based on the preprocessing of raw data. Finally, the proposed method is validated by using 2008 PHM data challenge competition data, which shows its effectiveness and practicality. Full article

Abstract: When a rotary machine is running, from which the acquired vibro-acoustic signals enable to reveal its operation status and health condition. The study proposed a DSP-based adaptive angular-velocity Vold-Kalman filtering order tracking (AV2KF_OT) algorithm with an online real-time nature for signal interpretation and machine condition monitoring. Theoretical derivation and numerical implementation of computation schemes are briefly introduced. An online real-time monitoring system based on the AV2KF_OT algorithm, which was implemented through both a digital signal processor (DSP) and a user interface coded by using
LabVIEWâ , was developed. Two experimental tasks were applied to justify the proposed technique, including (i) the detection of startup on the fluid-induced whirl performed through a journal-bearing rotor rig, and (ii) the decoupling of crossing orders from the measured signals of a multi-axle ball-bearing bench.
