Power Cable Analysis

Power Cable Analysis


Power cables, such as those found in subsea oil field operations, carry megawatts of power
to a variety of mission-critical pumps and motors. Several cables can be bundled together into
umbilicals that supply power to separate loads from a single source. Since these cables can
be very costly to design, manufacture and maintain, the analysis underlying their specification
must be thorough and accurate.

Products Used
ANSYS® Maxwell®, ANSYS Q3D Extractor®, ANSYS Simplorer®,
ANSYS Workbench™, ANSYS Mechanical ™, cable design kit

Introduction

Cable umbilical showing power conductors in the center with shields, hydraulic tubes, and armor strands

Power cable bundles include several sets of three-phase power groupings carrying several hundred amps at several thousand volts. The main power conductors consist of three separate phases of stranded copper, semiconducting wraps around the conductors to mitigate unintended accumulations
of charge, and high-strength dielectric insulation with individual shields to equalize and normalize the electric fields around high-voltage conductors. The entire cable bundle can be enclosed in steel strands that act as armor against unintended piercing. Each of the conductors can be slowly twisted
about themselves and the cable bundle’s center to create a more-structurally stable package.

Types of analysis typically performed for cables include:

• Cable losses due to frequency and proximity of conducting objects
• Cable electrical circuit (RLCG) and transmission line parameters
(characteristic impedance, propagation velocity)
• Field visualization (flux density, electric field intensity, current density)
• Effects of twisting on cable behavior
• Heating and temperature due to rated loads or unintended transients, such as short circuit
• Effects of loads run at different frequencies on bundle
• Effects of external seawater and flooding on cable

Parametric Analysis
Most cable analysis is done in 2-D, so the 3-D effect of twisting is accounted for by using parametric analysis of the axial position of the cable to capture the averaging effect of all possible twisting positions (Figure 2). Additional parametric analysis can include losses as a function of the fields; input currents are also of interest, as are cable material and geometry. High performance computing (HPC) can accelerate evaluating the large number of parameters involved in cable analysis.



System Integration

The cable can be represented in a circuit simulation using ANSYS Simplorer to account for various voltage excitations, such as square or sinusoidal. This helps to measure crosstalk or the eff ect of load transients, as seen in Figure 3. Circuit models are frequency dependent over a broadband range
of frequencies to capture the harmonic content of any reasonable signals, and the models are transmission line-capable to describe spatial wave effects along the cable’s length.

Cable Design Kit
Using the cable design kit as an add-on to ANSYS Maxwell or ANSYS Q3D Extractor, you can greatly compress the process — from problem defi nition and analysis to results extraction, shown in Figure 4. The design kit automates the input of common parameters for a set of typical cable confi gurations, generates all models needed for analysis, then analyzes and extracts the desired data. This process can greatly facilitate and automate the generation of parametric twist for 2-D models. A user can easily customize the design kit for any cable type of interest — it is written in Python, a widely used scientifi c computing language, which makes it easy to modify as needed.

Multiphysics
Electromagnetic losses can be used to determine the temperature within the cable by coupling with ANSYS Mechanical. The loss distribution is coupled spatially to capture any non-uniform heating eff ects. The effects are bidirectional: If the temperature change is large enough, the eff ect on electrogmagnetic resistance will automatically be determined. Figure 5 shows steady-state losses and temperature from a 200 A load.

Summary
ANSYS provides a robust solution for designing power cables used in subsea oil fi elds and other high-power applications. A comprehensive and automated multiphysics workfl ow provides ease of use along with accurate electromagnetic, circuit and thermal analysis of the cable prior to manufacture

ANSYS AIM 17.2: Expanding Upfront Simulation for the Design Engineer

The latest innovations for thermal management and bolted assemblies

With today’s latest release of ANSYS AIM, organizations can accelerate product design through upfront simulation, mitigate late-stage design changes, and reduce the number of costly physical prototypes. Now available, ANSYS AIM 17.2 enhances engineering simulation for thermal management, extends collaboration between designers and analysts, and brings upfront simulation to Japanese engineers in their own language.

“We are pleased that our customers continue to benefit from the rapid development of ANSYS AIM, allowing new applications to be solved with every release,” said Walid Abu-Hadba, chief product officer, ANSYS. “The new functionality in AIM will better enable engineers to push the boundaries of product design with its enhanced upfront simulation capabilities to speed up productivity and accurately predict product performance with ease.”  

AIM enables design exploration for every engineer by providing intuitive, guided workflows, accurate simulation results, and customization in a complete simulation tool covering a broad range of physics.  AIM’s ease-of-use simulation environment minimizes training and allows engineers to quickly become productive with simulation.

“ANSYS AIM's ease-of-use has allowed us to introduce key simulation skills and concepts to students using real industrial tools early in the engineering curriculum,” said Sanjeev Bedi, professor of engineering at the University of Waterloo.

Upfront simulation improves productivity of design engineers, by enabling them to make informed decisions early in the product’s life cycle, minimizing the need for re-work and re-design later in the process.

Highlights available in ANSYS AIM 17.2 include:

Thermal Management Advances
Optimizing heat transfer and thermal stress is a critical design issue for many industry applications, including heat exchangers, thermal mixing valves, engine components and electronic devices. Accurate predictions of the temperature and heat transfer in both the fluid and solid regions is essential to accurately predict the thermal and thermal-stress performance of the design. The new version of AIM builds upon its existing, combined fluid thermal and solid thermal-stress capabilities, supporting upfront simulation to optimize the thermal and fluid performance of product designs.
Momentum and heat sources are now available for fluid and conjugate heat transfer analysis, enabling simulations to include such features as electronic package power sources, fans and filters. Heat loads from a magneto-static solution can also be applied. Additionally, the new thermal transient simulation of solids allows time-dependent effects to be considered for solid thermal models with convection and radiation boundary conditions. Thermal effects can now also be included in polymer extrusion simulations. Combined, these new features and more improve the speed and fidelity of upfront simulation for thermal management.

Better Bolted Connections
Bolted connections between components are common elements in construction and machines. Accurately simulating bolt tightening sequences and the resulting contact pressures as well as frictional stresses between the parts is required to accurately predict the structural performance of bolted connections. ANSYS AIM 17.2 provides new options for optimizing bolted connections that allow engineers to correctly model loading and bolt tightening sequences for structural assemblies.

Enhanced Collaboration
Many of today’s industry leaders are working to improve their product creation processes by having design engineers perform upfront simulation. As part of these initiatives, design engineers may need to pass their simulation models to analysts to perform more advanced simulations or to validate their results. By leveraging the power of the ANSYS Workbench platform, AIM now enables collaboration among design engineers and simulation analysts through the drag-and-drop transfer of AIM simulation models to the flagship ANSYS Mechanical environment.

Support for Native Languages
Most product design engineers are more comfortable and productive when working with software in their native language. ANSYS AIM 17.2 introduces a Japanese language user interface, making upfront simulation more accessible than ever to Japanese-speaking engineers.
