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.

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

Stability analysis of the CCS power plant769

Abstract
This work shows the simulations performed using EMTP before and after tuning the PSS of the Coca Codo Sinclair hydro power plant (1500 MW) of the National Interconnected System of Ecuador. Each machin... see moree in the plant is modeled and its control systems (AVR and PSS) are represented by models created by the user and by library models. The results obtained are compared with real signals taken by the Wide Area Monitoring Systems.

In addition, the analyzes performed are shown, from a point of view of the transient stability of the plant, to determine the adjustment of the single-phase reclosing dead time of the San Rafael – El Inga transmission line, at 500 kV, taking into account the secondary arc model of the EMTP library.

Generic EMT type Model for Wind Parks763

Some presentation of the User Conference are available: https://www.emtp-software.com/support... Abstract : Utilities are under considerable pressure to increase the share of wind energy resources in their generation fleet. With the increasing share of wind energy resources, the dynamic behavior of power systems will change considerably due to fundamental differences in technologies used for wind and conventional generators. There is very little standardization in the ways to model wind turbines (WTs) and wind parks (WPs) in sharp contrast to conventional power plants. Hence, there is an international interest to deliver generic models (i.e. standardized and publicly available) for WTs and WPs that are able to capture all performance aspects as good as manufacturer-specific models. This research developed an electromagnetic transient (EMT) simulation model for full size converter (FSC) WT based WPs that can be used for stability analysis and interconnection studies. The considered topology uses permanent magnet synchronous generator. Although the collector grid and the FSC WTs are represented with their aggregated models, the overall control structure of the WP is preserved. FSC WT and WP control systems include the non-linearities, and necessary transient and protection functions to simulate the accurate transient behavior of WPs.</p>
