Book excerpt: Vigilant fault diagnosis and preventive maintenance has the potential to significantly decrease costs associated with wind generators. As wind energy continues the upward growth in technology and continued worldwide adoption and implementation, the application of fault diagnosis techniques will become more imperative. Fault diagnosis and preventive maintenance techniques for wind turbine generators are still at an early stage compared to matured strategies used for generators in conventional power plants. The cost of wind energy can be further reduced if failures are predicted in advance of a major structural failure, which leads to less unplanned maintenance. High maintenance cost of wind turbines means that predictive strategies like fault diagnosis and preventive maintenance techniques are necessary to manage life cycle costs of critical components. Squirrel-Cage Induction Generators (SCIG) are the prevailing generator type and are more robust and cheaper to manufacturer compared to other generator types used in wind turbines. A statistical model was developed using SCADA data to estimate the relationships between winding temperatures and other variables. Predicting faults in stator windings are challenging because the unhealthy condition rapidly evolves into a functional failure.

This book was released on 2020-04-01 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fault detection, control, and forecasting have a vital role in renewable energy systems (Photovoltaics (PV) and wind turbines (WTs)) to improve their productivity, ef?ciency, and safety, and to avoid expensive maintenance. For instance, the main crucial and challenging issue in solar and wind energy production is the volatility of intermittent power generation due mainly to weather conditions. This fact usually limits the integration of PV systems and WTs into the power grid. Hence, accurately forecasting power generation in PV and WTs is of great importance for daily/hourly efficient management of power grid production, delivery, and storage, as well as for decision-making on the energy market. Also, accurate and prompt fault detection and diagnosis strategies are required to improve efficiencies of renewable energy systems, avoid the high cost of maintenance, and reduce risks of fire hazards, which could affect both personnel and installed equipment. This book intends to provide the reader with advanced statistical modeling, forecasting, and fault detection techniques in renewable energy systems.

Available in PDF, EPUB and Kindle. Book excerpt: “Maintenance Management of Wind Turbines” considers the main concepts and the state-of-the-art, as well as advances and case studies on this topic. Maintenance is a critical variable in industry in order to reach competitiveness. It is the most important variable, together with operations, in the wind energy industry. Therefore, the correct management of corrective, predictive and preventive politics in any wind turbine is required. The content also considers original research works that focus on content that is complementary to other sub-disciplines, such as economics, finance, marketing, decision and risk analysis, engineering, etc., in the maintenance management of wind turbines. This book focuses on real case studies. These case studies concern topics such as failure detection and diagnosis, fault trees and subdisciplines (e.g., FMECA, FMEA, etc.) Most of them link these topics with financial, schedule, resources, downtimes, etc., in order to increase productivity, profitability, maintainability, reliability, safety, availability, and reduce costs and downtime, etc., in a wind turbine. Advances in mathematics, models, computational techniques, dynamic analysis, etc., are employed in analytics in maintenance management in this book. Finally, the book considers computational techniques, dynamic analysis, probabilistic methods, and mathematical optimization techniques that are expertly blended to support the analysis of multi-criteria decision-making problems with defined constraints and requirements.

Available in PDF, EPUB and Kindle. Book excerpt: As global warming is slowly becoming a dangerous reality, governments and private institutions are introducing policies to minimize it. Those policies have led to the development and deployment of Renewable Energy Sources (RESs), which introduces new challenges, among which the minimization of downtime and Levelised Cost of Energy (LCOE) by optimizing maintenance strategy where early detection of incipient faults is of significant intent. Hence, this is the focus of this thesis. While there are several maintenance approaches, predictive maintenance can utilize SCADA readings from large scale power plants to detect early signs of failures, which can be characterized by abnormal patterns in the measurements. There exists several approaches to detect these patterns such as model-based or hybrid techniques, but these require the detailed knowledge of the analyzed system. As SCADA system collects large amounts of data, machine learning techniques can be used to detect the underlying failure patterns and notify customers of the abnormal behaviour. In this work, a novel framework based on machine learning techniques for fault prediction of wind farm generators is developed for an actual customer. The proposed fault prognosis methodology addresses data limitation such as class imbalance and missing data, performs statistical tests on time series to test for its stationarity, selects the features with the most predictive power, and applies machine learning models to predict a fault with 1 hour horizon. The proposed techniques are tested and validated using historical data for a wind farm in Summerside, Prince Edward Island (PEI), Canada, and models are evaluated based on appropriate evaluation metrics. The results demonstrate the ability of the proposed methodology to predict wind generator failures, and the viability of the proposed methodology for optimizing preventive maintenance strategies.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This master thesis aims to demonstrate the effectiveness of a fault detection strategy in the structure of the wind turbine through a new strategy involving singular spectrum analysis (SSA), statistical methods and methods based on frequency. Based on a dynamic model of wind turbine, the time series behavior was obtained in the first instance without presenting any system failure and a second instance of system failure. From these series we can intervene with SSA and with statistical methods (variance, means, covariance, Fisher criteria) to design the fault detection system. The baseline will be designed with 850 healthy samples and a total sampling time of 6.25 seconds. This baseline which will provide us with the components to be compared so that the system can detect various faults that occur (fault types: fixed value, gain factor, offset and dynamics changed) in an efficient way. The results show that a sensor fault system with a high percentage of effectiveness was designed. The greater or lesser effectiveness thereof will depend on the established base line and the components used.

Available in PDF, EPUB and Kindle. Book excerpt: Maintenance costs have an important impact in wind energy profits. The main goal of this project is to implement a predictive maintenance framework as an added routine for controlling wind turbines status. Based on an statistical approach, this framework has a relevant impact in increase production and saving operational costs. Predictive maintenance methodology is based on an early warning system to detect failures (work orders emitted from the control system) before they occur. Two approaches are developed. Latent environmental and internal factors might be detected with power curve study, where individual power curve in a normal performance status is compared against individual empirical power curves in different states. On the other hand, specific part failures are more suitable to be found using normal models from sensors and then comparing with individual signals. Both ways end up with an on go failure detection system. Condition monitored data is extracted from turbines through SCADA, a system that provides sensor signals from different parts of the system. Failure data is processed from a the register of work order per machine.

Book excerpt: L'augment de la mida dels aerogeneradors per la generació d'electricitat i la seva construcció en llocs remots per maximitzar la producció suposa un augment en costos de manteniment i operació. Per tal de reduir aquests costos, eliminar manteniments programats i millorar la seguretat, apareix la necessitat de sistemes de control a distància. Structural health monitoring és el procés d'implantació d'una estratègia de detecció de fallades a l'estructura. Aplicat als aerogeneradors, fins i tot en condicions de vent canviants és necessària la detecció de dany. La primera part del projecte millora una metodologia prèviament aplicada als aerogeneradors (inferència estadística simple) reduint el temps de detecció; el segon mètode aplicat utilitza la inferència múltiple per detectar dany. Ambdós mètodes són provats per 24 mostres d'aerogeneradors en diferents condicions (sanes i danyades), i els resultats són encoratjadors: utilitzant la inferència simple el temps de detecció és reduït fins obtenir una detecció gairebé instantània; alhora, aquest projecte serveix com a prova pilot amb la inferència múltiple utilitzada per la detecció de dany en aerogeneradors, amb una correcta diagnosis d'estructures sanes i danyades.

Book excerpt: Aquest projecte té l'objectiu de demostrar l'efectivitat de dues estratègies de detecció de dany en l'estructura d'un aerogenerador, basades en l'obtenció d'un patró de referencia a través de l'anàlisi de components principals (PCA) en l'estructura sana de l'aparell. Quan recollim les dades de l'estructura de la qual en volem comprovar la seva integritat, les projectem sobre el patró i mitjançant dos tipus de test d'hipòtesis diferents –inferència estadística univariable i multivariable-, en podem definir el seu diagnòstic. També té l'objectiu d'utilitzar les dues estratègies per intentar, no només saber si l'estructura està danyada o no, sinó que també detectar quin tipus de dany l'afecta. Per tal de verificar el correcte funcionament dels plans de detecció de dany, analitzarem dades provinents d'estructures afectades per diferents tipus de dany que han estat generades a partir d'un simulador (FAST software). D'aquesta manera, podrem distingir si som capaços de diferenciar les dades d'un aerogenerador sa, de les d'un danyat.
