PS1 – Practical Experiences and new Developments of Process Bus
Assessment of Time-Critical IEC 61850 Process Bus Communications in a Virtualized Protection and Control System
The paper is centered on the impact analysis of time-critical IEC 61850 process bus communication on the performance and scalability of a Centralized P&C solution designed to operate in a virtualized environment able to instantiate multiple P&C intelligent electronic devices A comprehensive analysis of the response times of a high-performance line protection function is discussed, including a comparative study of critical functions running on centralized and distributed DSAS architectures.

PS1 – Practical Experiences and new Developments of Process Bus
DSAS Rollout Experience – Picking the Ripe Fruits
The paper focuses on the most significant challenges for wider adoption of Digital Substation technology: full dependency on high-precision time synchronization, critical data availability and redundancy, process bus network infrastructure complexity and overall configuration of the system. For each of these challenges, novel approaches are presented, that maximize the availability and reliability of the system without increasing too much its overall cost.

PS2 – Advances in Transformer Analytics
Analysis of Simplifications and Accuracy of a Thermal-hydraulic Model of Core-type Power Transformer Winding
Utilizing CFD as a regular engineering tool would provide powerful insights on the thermal-hydraulic phenomena inside the power transformer. This study addresses the simplifications that can be done to accomplish it, obtaining results faster with 2D simulations without compromising precision.

PS2 – Advances in Transformer Analytics
Evaluation of the Hot-Spots’ Location during Dynamic Loading of a Natural Ester Cooled Power Transformer
Current energy demands subject transformers to rapid changes in their operating conditions. Since the hot-spot’s temperature and location in the transformer are linked to its life expectancy, this study investigates location shifts, providing results from experimental tests and CFD transient simulations.
