Discussion Overview
The discussion centers on whether the Psti and Plti values decrease when the measured Pst and Plt values at low voltage (LV) are transposed to high voltage (HV). It involves concepts related to the quality of AC power and power-line flicker, exploring the implications of voltage transformation on these parameters.
Discussion Character
- Technical explanation
- Conceptual clarification
- Debate/contested
Main Points Raised
- Some participants suggest that the Psti and Plti values may decrease when transposing Pst and Plt from LV to HV, but this is not explicitly confirmed.
- One participant provides context by explaining that Pst and Plt are related to flicker emission limits in power distribution networks, indicating that flicker is a result of rapid voltage fluctuations.
- Another participant argues that flicker is a multi-cycle effect and posits that it will not be significantly attenuated by the LV to HV transformation at the generation site, implying that the transformation does not address the underlying flicker issue.
- A further suggestion is made that reducing flicker from static inverters would require a mechanism similar to a synchronous motor/generator with a heavy flywheel, indicating a potential approach to mitigate flicker.
Areas of Agreement / Disagreement
Participants express differing views on the impact of LV to HV transformation on flicker and Psti/Plti values, indicating that the discussion remains unresolved with multiple competing perspectives.
Contextual Notes
The discussion may be limited by assumptions regarding the behavior of flicker during voltage transformation and the specific characteristics of the equipment involved. The dependency on definitions of Pst and Plt and the nature of flicker effects are also relevant but not fully explored.
