Course Outline
This course will cover the following aspects of HV power cable current rating calculations. ELEK Cable HV Software will be used extensively for the hands-on modelling.
Fundamentals of Cable Rating Calculations
- The fundamental current rating equations explained.
- Ladder network of a cable system explained.
- The main standards and technical references.
- What are dielectric and joule losses, thermal resistances (and capacitances), and how are they calculated?
- What is load factor and how is it calculated?
- How do you calculate cable temperatures?
- Understanding the current rating for various installation methods:
- Cables in air and trays.
- Groups of cables.
- Buried cables and in backfill.
- Soil drying out.
- Cables in ducts.
- Unfilled troughs.
- Ventilated tunnels.
- Riser poles.
- Offshore J/I-tubes.
- Submarine (underwater).
- Hands-on calculations and modelling by the attendees for the various installation methods.
Transient and Dynamic Cable Rating Calculations
- Emergency and cyclic cable ratings explained.
- What is the complete transient response of a cable?
- How do you calculate emergency rating?
- How do you calculate cyclic rating to IEC 60853-2 and Neher-McGrath methods?
- Hands-on case studies calculating the emergency ratings for a HV cable transmission line and the cyclic rating.
Power Cable Modelling
- What are the main components of a power cable?
- General and layer-specific modelling guidance points.
- How do we model the cores, conductors, insulation, screens, sheaths, armour, external coverings, and pipes?
- How should lay length be considered?
- How do you properly model cables from manufacturer datasheets?
- How do you accurately model a three-core cable with magnetic armour?
- What are the maximum operating temperature limits and how do we apply them?
- HVDC electrical stress-limited rating explained.
- Hands-on practical modelling of different cable types including, MV 1/3C, DC solar, 3C armoured submarine, sector-shaped, oil-filled, HVDC, and pipe-type.
Finite Element Modelling of Cable Systems
- How do finite element method (FEM) calculations work for cable ratings?
- What are the drawbacks and limitations of IEC 60287?
- What are the benefits of using FEM for cable ratings?
- Non-isothermal and isothermal assumptions explained.
- Touching versus non-touching cables.
- How do the ratings from FEM compare with IEC 60287?
- Hands-on design using FEM to model an installation comprising multiple buried circuits within multi-zoned soil.
Bonding Arrangements
- Why and when do we use special sheath bonding arrangements?
- How do you calculate circulating and eddy current sheath losses?
- How do the losses affect the cable rating?
- How do you calculate sheath standing voltage and what is the safe limit?
- The following bonding methods are explained:
- Solid bonding.
- Single-point bonding.
- Cross-bonding.
- What are the design considerations, advantages and disadvantages for the different methods?
- How do phase spacings, transpositions, and section lengths affect the cable rating?
- How do you specify an earth continuity conductor (ECC) and a sheath voltage limiter (SVL)?
- Hands-on practical exercises teaching the different bonding arrangements.
Special Calculations
- How are sequence impedance calculations performed?
- What are the safe limits for magnetic field density and how is it calculated?
- What are the affects on ratings of multiple cable crossings?
- How do you calculate the rating of cables in filled (and covered) cable trays?
- How do you calculate cable short-circuit ratings?
- What is the rating for deeply buried cables?
- Hands-on modelling of various case studies including crossing of MV cable with multiple LVDC cables in a solar farm.
Prerequisites
An understanding of basic cable system concepts such power cable types and construction, what is current rating and why is it needed, what are bonding arrangements, will help.
You will need to have access to a licenced copy of ELEK Cable High Voltage Software. A general awareness of what the software is for, and its applications would be beneficial.
Please contact us if you would need to organise a licenced copy of ELEK Cable HV for the course.
