SUMMARY

The discussion centers on the impact of transposing Pst and Plt values from low voltage (LV) to high voltage (HV) on the Psti and Plti values. It is established that the quality of AC power, particularly regarding flicker emission limits, is crucial for energy users on a power distribution network. Pst represents short-term flicker, while Plt denotes long-term flicker. The consensus is that flicker will not be significantly reduced during the LV to HV transformation due to the absence of energy storage in the step-up transformer, necessitating alternative solutions like synchronous motors with flywheels to mitigate flicker from static inverters.

PREREQUISITES
  • Understanding of AC power quality metrics, specifically Pst and Plt

Do Psti and Plti values decrease when the measured Pst and Plt (@LV) is transposed to HV?

Could you provide a context to this question?

Welcome to PF.
I guess the subject is; The quality of AC power. Flicker emission limits for energy users on a power distribution network.
Pst; short term parameter.
Plt; long term parameter.
Power-line flicker is a visible change in brightness of a lamp due to rapid fluctuations in the voltage of the power supply. The voltage drop is generated over the source impedance of the grid by the changing load current of an equipment or facility. These fluctuations in time generate flicker.

Flicker is a multi-cycle effect. I see nowhere to store several cycles of energy in the step-up transformer. I therefore assume that flicker will not be significantly attenuated by the LV to HV transformation at the generation site.

To reduce flicker from static inverters would require something equivalent to a synchronous motor/generator, with a heavy flywheel.
