Use of FEA Methods in Verifying High-Voltage Insulation Systems

The discovery of new materials and manufacturing capabilities has seen a shift in how we use insulation materials and the design of insulation systems. An example is the increased use of composite materials for high-voltage applications in the last decade. The development of new tower designs (e.g., T-Pylon and insulating crossarms) is seeing insulators being used in different orientations, also giving rise to the use of insulators for nonconventional profiles (and increased diameters). Designing such new systems requires an increased amount of laboratory testing and research. This can be time consuming and resource intensive (both from a personnel and a financial perspective). Finite element analysis (FEA) methods minimize laboratory testing by allowing several designs and iterations of insulation systems before fabrication and prototyping. Whilst FEA methods are not a replacement for laboratory testing, they provide the necessary confidence before large-scale testing. The present research work will show the development of a composite insulator from a research idea to a full-scale prototype, designed and verified using both the laboratory and FEA methods.

Helping to Keep the Lights on: Stochastic Nonlinear Coupled Analysis of the UK Advanced Gas-Cooled Reactors

The UK advanced gas-cooled reactor (AGR) fleet has been commercially generating low-carbon electricity since the 1980s, presently owned and operated by EDF Energy. The reactor design is somewhat unusual in that it uses a core of graphite bricks for the neutron moderator and carbon dioxide as the coolant. One aspect of the safety case that has come under particular scrutiny is the expected evolution of the graphite bricks and the expectation that they will crack late in the life of the reactor. Safe operation of the reactor has to be maintained at all times by ensuring that the reactor cores do not evolve to a state that is unacceptable under the current safety case. Knowledge of when bricks crack and how they subsequently evolve is therefore important.

The focus of the work in the COMSOL Multiphysics® software for EDF Energy has been to construct a diverse assessment of the reactor brick evolution, largely independent of their own internal modeling approaches, that could be used to predict the evolution of the shape of the bricks and the rate at which keyway root cracking will occur. The approach combines statistical models of the main model inputs, a nonlinear coupled mechanical model of the graphite, and the Monte Carlo approach to determine the cracking rates. The COMSOL Multiphysics® numerical model couples standard components of the add-on Structural Mechanics and Geomechanics modules for linear elasticity and thermal effects with customized partial differential equation (PDE) and ordinary differential equation (ODE) physics models to represent the highly specific "creep" and other, related processes that occur in graphite when in such an extreme environment. The results of the models have been compared against recent reactor data and have been found to give an excellent representation of keyway root crack progression and brick shapes, with only minimal tuning against the observations required.

Coffee Break
12:15

Learn how to convert a model into a custom app using the Application Builder, which is included in the COMSOL Multiphysics® software. You can upload your apps to a COMSOL Server™ installation to access and run the apps from anywhere within your organization.

13:00
Break for Lunch
14:00

This minicourse will provide an introduction to modeling with the Electrochemistry Module and Chemical Reaction Engineering Module, add-ons to the COMSOL Multiphysics® software. We will start by giving an overview of the functionality and presenting some application examples. The course will then describe in detail the coupling between electric potential in the electrode, electrolyte, and electrode kinetics, as well as the ability to model electrode reactions and chemical species transport. During a model demonstration, you will learn how to model a simple chlor alkali fuel cell.

14:45
Coffee Break
15:00

When the wavelength of the electromagnetic radiation is considerably greater than the length scale of your object, the wave propagation through your object can be neglected and a quasi-steady-state problem can be solved. This minicourse will explore the capabilities of COMSOL Multiphysics® for modeling electromagnetics applications in the static and low-frequency regimes using the AC/DC Module. This course will include a review of how current-carrying coils can be modeled to compute the magnetic field and induced currents.

15:45
Coffee Break
16:00

When presenting your results, the quality of your postprocessing will determine the impact of your presentation. This minicourse will explore the many tools in the Results node designed to make your data look its best. These include mirroring, revolving symmetric data, cut planes, cut lines, exporting data, joining or comparing multiple data sets, as well as animations.
