Laboratory or in-field measurements are sometimes thought-about the gold normal for sure facets of energy system design; nevertheless, 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 are typically not possible to measure straight. 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 entails corona efficiency testing of high-voltage transmission line {hardware}. Corona-free insulator {hardware} efficiency is crucial 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 area constraints often prohibit testing to a partial single-phase setup. This requires establishing equivalence between the laboratory setup and real-world three-phase situations. In follow, this may be troublesome to do, however fashionable simulation capabilities can assist. The second case entails submarine HVDC cables, that are generally used for offshore wind interconnects. HVDC cables are sometimes thought-about 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 regulation. Thus, externally induced electrical fields can exist across the cable and are inside a variety detectable by varied aquatic species.
Key Takeaway:
- Discover ways to use fashionable simulation to translate single-phase laboratory corona mockups into correct three-phase real-world efficiency for 500 kV and 765 kV methods.
- Discover the physics behind how ocean currents interacting with HVDC submarine cables create induced electrical fields—a phenomenon typically neglected however detectable by aquatic species.
- Achieve actionable insights into leverage simulation to cut back design prices and bypass the bodily area constraints that usually stall conventional testing.
- See a sensible utility of electromagnetic concept as we exhibit how relative movement in static magnetic fields necessitates simulation the place direct measurement is unfeasible.
