Fault Diagnostics for Electrically Operated Pitch Systems in Offshore Wind Turbines

2016

This paper investigates the electrically operated pitch systems of offshore wind turbines for online condition monitoring and health assessment. The current signature based fault diagnostics is developed for electrically operated pitch systems using model-based approach. The electrical motor faults are firstly modelled based on modified winding function theory and then, current signature analysis is performed to detect the faults. Further, in order to verify the fault diagnostics capabilities in realistic conditions, the operating profiles are obtained from FAST simulation of offshore wind turbines in various wind conditions. In this way, the applicability of current signature analysis for …

Enhanced flexible algorithm for the optimization of slot filling factors in electrical machines †

2020

The continuous development in the field of industrial automation and electric mobility has led to the need for more efficient electrical machines with a high power density. The improvement of electrical machines’ slot filling factors is one of the measures to satisfy these requirements. In recent years, this topic has aroused greater interest in the industrial sector, since the evolution of the winding technological manufacturing processes allows an economically sustainable realization of ordered winding arrangements, rather than random ones. Moreover, the manufacture of electrical machines’ windings must be preceded by an accurate design phase in which it is possible to evaluate the maximu…

Low-Temperature Solution Processable Electrodes for Piezoelectric Sensors Applications

2013

Piezoelectric thin-film sensors are suitable for a wide range of applications from physiological measurements to industrial monitoring systems. The use of flexible materials in combination with high-throughput printing technologies enables cost-effective manufacturing of custom-designed, highly integratable piezoelectric sensors. This type of sensor can, for instance, improve industrial process control or enable the embedding of ubiquitous sensors in our living environment to improve quality of life. Here, we discuss the benefits, challenges and potential applications of piezoelectric thin-film sensors. The piezoelectric sensor elements are fabricated by printing electrodes on both sides of…

Abstract As the use of digitalization and automated decision-making becomes more common in the public sector, civil servants and clients find themselves in an environment where automation and robot technology can be expected to make dramatic changes. Social service delivery in Trelleborg, Sweden, is the setting for a case study of the goals, policies, procedures, and responses to a change in how social assistance is delivered using automated decision-making. Interviews with politicians and professionals complemented with government documents and reports provide the empirical data for the analysis. Four value positions: Professionalism, Efficiency, Service, and Engagement, are used as the an…

Are robots in rich countries a threat for employment in emerging economies?

2022

The effects of robotization on labor market outcomes have been widely investigated within developed countries. Conversely, few studies have tried to assess how automation in advanced economies affects less industrialized countries. In this work, we analyze the impact of robotization in a group of developed European countries (EU15) on employment dynamics in a country-industry panel data of emerging markets. Our findings indicate that EU15 robotization is associated with a decline of sectoral employment in emerging economies, especially in Asia, tradable and more robotized industries. Ultimately, a small set of major European countries - namely, Germany, Italy, Denmark and United Kingdom - s…

The interaction effects of automation and population aging on labor market

2022

Automation and population aging are two major forces that will shape the nature of works in the future. However, it is not clear how these forces will interact with each other and affect the labor market. This paper examines the interaction effects of computerization and population aging on the labor market. We found that computerization and population aging have large and statistically significant effects on employment growth but not earnings growth. Also, their interaction terms are statistically significant only for employment growth but not for earnings growth.

Experimental validation of the BAC factor method for lighting systems

2017

In the last few years, many buildings have been equipped with Building Automation and Control (BAC) systems. BAC systems can be used to achieve a significant reduction of the electrical consumption and to have all the well acknowledged benefits from the daylight (e.g. occupant comfort, health, well-being and productivity). For this reason, Standard EN 15232 "Energy performance of buildings — Impact of Building Automation, Controls and Building Management" puts into evidence the importance of the presence of BAC and Technical Building Management (TBM) systems, suggests a classification of these systems, explains their main functionalities and presents a simplified method to estimate their im…

Intelligent robotic cell for Trencad/spl inodot//spl acute/s mosaics manufacturing

2005

The purpose of this paper is the description of an application for the complete automation of a mosaics manufacturing process with irregular random pieces, so called trencad/spl inodot//spl acute/s. An intelligent robotic cell has been implemented by using intelligent methods and pattern recognition techniques to assemble unpredictable objects in an autonomous manner.

A set of indices to assess the real performance of daylight-linked control systems

2017

Abstract The installation of Building Automation Control Systems (BACs) in general is an effective action to achieve relevant energy savings. Commercial BACs, installed in residential or small offices, often include functions of lighting control, acting as Daylight-Linked Control Systems (DLCSs). Nevertheless, because system performance is strictly dependent on different parameters, BAC’s hardware and software configuration and as well as an inaccurate commissioning do not always allow a perfect execution of the desired tasks; therefore, the system could not work as expected. Moreover, it is well known that energy saving potential is specifically related to the variability of the light envi…
