Operation and Intelligent Fault Diagnosis of Hydropower Units Under New Power Systems

Dear Colleagues,

Hydropower units are critical components in new power systems, and their stable, efficient, and safe operation is essential for supporting the integration of renewable energy and enhancing grid resilience. With the rapid development of sensing technologies, signal processing methods, and artificial intelligence, significant progress has been made in monitoring operational states, diagnosing faults, and predicting performance degradation. This Special Issue focuses on the operational challenges and intelligent fault diagnosis technologies used for hydropower units in the context of new power systems driven by carbon neutrality goals.

We welcome the submission of original research articles and reviews covering topics such as operational monitoring methods, noise reduction and signal denoising strategies, fault diagnosis and classification techniques, and predictive maintenance approaches for hydropower units. Studies involving vibration analysis, cavitation detection, sediment wear assessment, and characteristics of hydraulic transition processes are also encouraged. Special attention will be given to contributions that integrate experimental results, numerical simulations, and artificial intelligence algorithms (e.g., machine learning, deep learning) to enhance operational decision-making and fault prediction. By gathering interdisciplinary insights, this Special Issue aims to promote technological progress and best practices for the long-term reliability of hydropower facilities.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
