Description

To accommodate the TapChanger/TapChangerControl model for distribution circuit regulator.

It is therefore needed that ‘secondary units’ to add to description for RegulatingControl.targetValue and some other UML updates consist of:
• One new attribute: TapChangerControl.minLimitVoltage
• One renamed attribute: TapChangerControl.limitVoltage to TapChangeControl.maxLimitVoltage

Besides, lots of description tweaks needed in the attached document.

Proposed Solution

One new attribute: TapChangerControl.minLimitVoltage
One renamed attribute: TapChangerControl.limitVoltage to TapChangeControl.maxLimitVoltage

And a few classes/attributes descriptions clean-up and tweaks. Details can be found in the attached document.

Decision

[03/30/2022] WG13 agrees with the changes proposed.

Oslo, 13 June 2023

The following changes are on hold and need to be considered in the control clean up:
TapChanger.initialDelay to RegulatingControl.initialDelay
TapChanger.subsequentDelay to TapChangerControl.subsequentDelay
Remove ShuntCompensator.aVRDelay in favor of RegulatingControl.initialDelay

Note that for ctRatio and ptRatio were added to TapChanger, but these attributes are also in TapChangerInfo. Should we delete them from TapChangerInfo?
=> The decision is that we keep it like it is so the attributes will exist on 2 places. The usege is different.

Question: Should ptRatio and ctRatio be added to 452 EQ?
=>The decision is Yes. To be decided in which profile - probably in the unbalance profile as it was needed for the distribution

Another question: TapChangerControl.maxLimitVoltage and minLimitVoltage are not in 452, Should we add them?
=> We need to add them to 456 - SSH unbalanced

Also look at issue 3808 related to master-follower.

Release Notes

The following changes are applied to 301
- added TapChanger.ctRatio
- added TapChanger.ptRatio

- update of TapChangerControl description
- TapChangerControl.limitVoltage renamed to maxLimitVoltage and description updated
- TapChangerControl.minLimitViltage added
