Aster,

I suppose I need to watch how I phrase it, when I say we, I meant we (PGDTF), not we (CPS Energy). J

I was making an assumption that there are no effects from GMD because PGDTF has left it out of the guide, however, it could have just been an oversight. As a voting member of the ROS, I will have a hard time endorsing this document if it doesn’t give some direction on high-bus diff.

 

 

 

 

Kenneth,

Yes you can add a section about high bus protection.

Thanks,

Aster

Aster,

Just a quick question of whether we can add a subsection in Section 5 to speak to high-bus protection, even if it’s just to say that high-bus diff relays won’t be effected by GMD.

 

 

 

 

PGDTF members,

Attached is the final draft of “Methodology for Assessing GMD Impacts on ERCOT Power Systems” that I will be emailing to ROS for approval in ROS August meeting . From our last meeting section 5.1 is updated and also some formatting. I have not received any comment from SPWG System Protection Working Group. Please email me if you have any comment by July 31, 2019.   

 

Thanks

Aster Amahatsion

PGDTF Chair 2019
