Measurements for Condition Monitoring of Hydropower plants: A Review

Abstract

Condition monitoring is an extension of the predictive maintenance or proactive maintenance process for detecting faults in a machine component with the help of pre identified measuring parameters to identify a significant change which is indicative of a developing fault. The fault developed due to various factors in the hydropower plants can damage or halt the operation of power plants. The literatures on the measurement process for condition monitoring of power plants has been reviewed and discussed. Since condition monitoring is a newer and a broader topic, few literatures were available and they were review on the basis of measurement and faults detection processes.

Models for a hydropower plant: a review

“…Accordingly, the methods used for modelling also vary to a wide category based on the application of the model. Some of them are developed for planning studies while others are developed for control, transient response, study of dynamics, condition monitoring, etc (de Mello et al, 1992;Kishor, Saini and Singh, 2007;Valavi and Nysveen, 2018a;Liu et al, 2019;Sapkota et al, 2022). A single hydropower has many components starting from water reservoir and flow regions, mechanical rotating parts to the static electric parts in general (Quiroga OD, 2000;Rheinheimer et al, 2023).…”

“…Models made for condition monitoring are concerned with the sensor data and its analysis (Z. Wenjing, 2017;Liu et al, 2019;Tor Inge Reigstad and Uhlen, 2020a;Kerdphol et al, 2021;Reigstad and Uhlen, 2021;Kincic et al, 2022;Sapkota et al, 2022) This paper attempts to present a brief review of the hydropower models found widely in the literature by classifying them into three major categories which are (i) Models for Control and Optimization, (ii) High Resolution models (CFD models) and (iii) Models for planning and Operational studies. Although we may derive specific sub-categories even under these three major categories and critically review each of them, this paper is aimed at studying the 'Models for control and Optimization' in detail and will present only a brief overview and major modelling gap for the other two.…”
