Synchronous condenser transformer energization with PAMSUITE781

Abstract
In engineering studies, getting the necessary input data for performing EMTP simulations may be one of the most challenging tasks.
Indeed, the characteristics of the system under study are usual... see morely badly known for a number of reasons: sometimes they are known with some inaccuracy.
For example when parameters are associated with tolerances; sometimes, the characteristics are completely unknown, for example when the equipment is very old and the datasheets are not available, or when the study is about a future project for which many equipment characteristics are not known yet.

EMTP® studies for IBR integration at Hydro-Quebec777

Abstract
Abstract:

Hydro-Quebec has been involved in EMTP® development since the 80s and has collaborated with several organizations worldwide through the Development Coordination Group of EMTP (DC... see moreG-EMTP). Hydro-Quebec was the key player in the EMTP recoding project that allowed the delivery of the latest generation of the software in 2003. The new EMTP was developed at IREQ (Hydro-Quebec’s research center) from 1998 to 2003.

Hydro-Quebec was the first organization to simulate its complete transmission grid in EMTP. Hydro-Quebec was also the first system operator to require that manufacturers of wind turbines provide detailed EMT-type (EMTP®) models for wind park integration studies. This webinar will present:
• How EMTP simulations are integrated into Hydro-Quebec’s work process?
• How EMTP simulations can complete RMS simulations?
• Future simulation challenges

Speakers:
• Karine Gauthier, ing.
• Pascal Prud’homme, ing.
• Saad Omar, ing.

Transient immunity assessment of wind and solar parks773

Abstract
Abstract
Inverter-base Resources (IBRs), such as solar photovoltaic (PV) and wind parks are subject to transients which may cause more issues as compare to traditional generation due to the colle... see morector grid and the geographical spread between converters. In this webinar, we present several challenges which may be faced by planners and park developers:
- Transient immunity against utility-owned capacitor bank switching. Assessment of IEEE Std 1547-2018.
- Ferroresonance after open-phase faults.
- Temporary overvoltage (TOV) in a PV parks after a phase-to-ground fault
Events and EMTP simulations will be described and analysed during the webinar.
This work was performed with the collaboration of Bob Arritt, EPRI and Chest Li, Hydro One
