Laboratory or in-field measurements are sometimes thought of the gold commonplace for sure elements of energy system design; nonetheless, measurement approaches at all times have limitations. Simulation can assist overcome a few of these limitations, together with dashing up the design course of, lowering design prices, and assessing conditions which can be usually not possible to measure instantly. On this presentation, we are going to focus on two examples from the ability system trade.
The primary case we are going to focus on includes corona efficiency testing of high-voltage transmission line {hardware}. Corona-free insulator {hardware} efficiency is important for operation of transmission traces, significantly at 500 kV, 765 kV, or increased voltages. Laboratory mockups are generally used to show corona efficiency, however bodily house constraints often limit testing to a partial single-phase setup. This requires establishing equivalence between the laboratory setup and real-world three-phase circumstances. In observe, this may be troublesome to do, however trendy simulation capabilities can assist. The second case includes submarine HVDC cables, that are generally used for offshore wind interconnects. HVDC cables are sometimes thought of to be environmentally inert from an exterior electrical area perspective (i.e., electrical fields are contained within the cable, and the cable’s static magnetic fields induce no voltages externally). Nevertheless, simulation demonstrates that ocean currents shifting via the static magnetic area fulfill the relative movement requirement of Faraday’s legislation. Thus, externally induced electrical fields can exist across the cable and are inside a variety detectable by numerous aquatic species.
Key Takeaway:
- Learn to use trendy simulation to translate single-phase laboratory corona mockups into correct three-phase real-world efficiency for 500 kV and 765 kV programs.
- Discover the physics behind how ocean currents interacting with HVDC submarine cables create induced electrical fields—a phenomenon usually neglected however detectable by aquatic species.
- Acquire actionable insights into tips on how to leverage simulation to cut back design prices and bypass the bodily house constraints that always stall conventional testing.
- See a sensible utility of electromagnetic idea as we display how relative movement in static magnetic fields necessitates simulation the place direct measurement is unfeasible.
