Anomaly indicators for Kaplan turbine components based on patterns of normal behavior
(Chapter; Peer reviewed, 2018)This paper describes and proposes some indicators for continuous monitoring of anomalous conditions in the hydraulic system of a Kaplan turbine using SCADA data. The indicators are based on significant deviations between ... -
Anskaffelse av måleutstyr for måling på fire hurtig-ladestasjoner for elbil
(SINTEF Energi. Rapport;TR A7440, Research report, 2014)Prosjektet ble gjennomført svært nær de planlagte rammer. Prosjektet har vist merverdi av avanserte målinger på hurtig-ladestasjoner inkludert mulighetene til å se hurtige/transiente forløp i strøm og spenning ved tilkobling ... -

Apparatus for loss measurements under multidirectional and dc-bias flux in electrical steel laminations
(Peer reviewed; Journal article, 2020)Conventional standardized power loss measurements for electric steels are performed at flux densities with a single sinusoidal and unidirectional excitation. However, the flux inside electrical steel laminations can deviate ... -
Apparent impedance analysis: A new method for power system stability analysis
(IEEE Workshop on Control and Modeling for Power Electronics, COMPEL;2016, Chapter, 2016)In this paper a new method for power system stability analysis is introduced. The method is based on injection of a small voltage or current in an arbitrary point of the system. The apparent impedance is defined as the ... -
Application of a Central Composite Design for the Study of NOx Emission Performance of a Low NOx Burner
(Journal article; Peer reviewed, 2015) -
Application of a Testing Chain Methodology for Improving Power Converter Controllers
(Chapter; Peer reviewed, 2020)The practice of testing power system equipment like converters usually involves simulation, laboratory and field testing in that sequence. Such an approach lacks smooth transition and wide coverage of new services which ... -
Application of Advanced Technologies for CO2 Capture From Industrial Sources
(Peer reviewed; Journal article, 2013)The great majority of the research on CO2 capture worldwide is today devoted to the integration of new technologies in power plants, which are responsible for about 80% of the worldwide CO2 emission from large stationary ... -
Application of Bayesian Networks in Distribution System Risk Management

Application of radar data to estimate distributed return periods of extreme rainfall events over Trondheim
(SINTEF Energi. Rapport;, Research report, 2013)The return period of a given rainfall intensity is an important parameter for the Trondheim municipality since the drainage systems in Trondheim have been and are still being designed on the basis of a selected return ... -
Application of Three-Dimensional CFD Model to Determination of the Capacity of Existing Tyrolean Intake
(Peer reviewed; Journal article, 2024)CFD models of intakes in high-head hydropower systems are rare due to the lack of geometric data and cost of modeling. This study tests two different types of software to see how modeling can be performed in a cost-effective ... -
Application range of the HEM approach for CO2 expansion inside two-phase ejectors for supermarket refrigeration systems
(Peer reviewed; Journal article, 2015)In this study, the accuracy of the homogeneous equilibrium (HEM) applied to 3-D CFD-based simulations of CO2 expansion inside two-phase ejectors is presented. The HEM approach previously reported in the literature were ... -
Applications of Big Data and Data Science in the Electricity Distribution Grid - State-of-the-art
(SINTEF Rapport;, Research report, 2020)Almost every household in Norway has a smart electricity meter installed. The advanced functionality of the meters and the large amounts of data transmitted from them have the potential to contribute to more than just a ... -
Applying Endogenous Learning Models in Energy System Optimization
(Peer reviewed; Journal article, 2021)Conventional energy production based on fossil fuels causes emissions that contribute to global warming. Accurate energy system models are required for a cost-optimal transition to a zero-emission energy system, which is ... -
Applying successive linear programming for stochastic short-term hydropower optimization
(Journal article; Peer reviewed, 2016)We present a model for operational stochastic short-term hydropower scheduling, taking into account the uncertainty in future prices and inflow, and illustrate how the benefits of using a stochastic rather than a deterministic ... -
Applying Vector Fitting for Measurement-based Multiple-Input Multiple-Output Model Identification of a Grid-Forming Converter
(Chapter; Peer reviewed, 2023)This paper presents an approach for applying Vector Fitting (VF) to identify a small-signal state-space model of a power electronic converter represented as a multiple-input multiple-output (MIMO) system. A workflow for ... -
Approximating Ramping Constraints in Hydropower Scheduling
(International Conference on the European Energy Market;19, Chapter; Peer reviewed, 2023)This work concerns the modeling of ramping constraints on discharge in medium-term hydropower scheduling models applied in a liberalized market context. Such models often apply a coarse time discretization to ensure ... -
Approximating the flow-based domain for long-term market analysis in hydropower-dominated power systems
