EMTDC Engine and Model Updates in PSCAD v5.1
In this video, we are going to look at the major algorithmic developments behind the EMTDC simulation engine in PSCAD v5.1.0. We will explore parallel subsystem solving, improved branch and transformer processing, GPU sparse algorithm integration, and resource management using EMTDC and PSCAD thread controls.
Key Topics Covered:
00:12 Subsystems Solved in Parallel – An overview of multi-threaded subsystem solving, which allows multiple subsystems to be computed simultaneously across different threads to boost simulation speeds for multi-subsystem projects.
00:26 Improved Ideal Branch and Transformer Processing – How cached memory is utilized to accelerate execution, especially in projects containing many ideal branches or transformers.
00:40 GPU Sparse Algorithm Enabled for EMTDC – Utilizing GPU processing power via an alternative sparse algorithm alongside the legacy sparse algorithm by toggling project settings.
01:05 EMTDC Thread Control – Managing system resources by adjusting thread limits in the Compiler Advanced Options, with a default setting of 8 parallel threads.
01:16 PSCAD Processor Control – Understanding how PSCAD and EMTDC coordinate, managing thread limits when running on the same computer, and using the Live Button to synchronize them for online controls at the cost of speed.
